Plane vs OpenProject: Which should you choose in 2026?

Choosing an open-source project management tool means deciding what kind of system your teams will work in every day and whether it can support the way that work evolves over time.

Plane and OpenProject both offer open-source foundations, self-hosting options, and alternatives to tools like Jira. They differ considerably in how they approach planning, collaboration, customization, and deployment.

For teams looking for layered planning through Initiatives and work items, a workspace-level Wiki, native AI and Agents, and multiple self-hosting options, Plane brings those capabilities into one project management system.

In this guide, we break down the differences across features, customization, deployment, pricing, and self-hosting.

TL;DR

Core differences at a glance

One workspace for planning, docs, and execution

Plane brings planning, execution, documentation, and collaboration into a single workspace. Instead of stitching together separate tools for tracking work, writing docs, managing sprints, and handling intake requests, Plane keeps everything connected under one login.

Here is what ships inside Plane today:

• Project management with five layout views (List, Board, Calendar, Gantt, Spreadsheet) on every tier, including Free
• A workspace-level Wiki with a rich-text editor, slash commands, embeds, nested pages, version history, and PDF and DOCX export
• Cycles, Modules, Milestones, and Initiatives for sprint planning, project delivery, milestones, and strategic coordination
• Native time tracking for estimates, worklogs, and reporting
• Intake forms and email capture for structured requests from internal teams or external clients
• Workflows and automations with trigger-and-action rules and approval processes
• Integrations with GitHub, including GitHub Enterprise Server, GitLab, including self-managed GitLab, Slack, Sentry, and more
• Cloud, self-hosted, and air-gapped deployment, with air-gapped deployments available through Enterprise Grid

OpenProject organizes functionality across separate modules: Work Packages, Backlogs, Meetings, Wiki, Forums, Budgets, and the new Documents feature. Some of the most requested capabilities, like Kanban-style action boards that automatically update work package attributes when cards are dragged between columns, require a paid Enterprise plan. Plane includes full Board view on every tier, including free.

The total cost of ownership

Choosing a project management tool is a long-term commitment. Migrating data, retraining teams, and rebuilding workflows after a year costs more than most teams budget for. So the real question is not just "what does it cost per seat?" but "what will I actually pay when I account for everything?"

Both Plane and OpenProject offer free self-hosted editions. The comparison gets more interesting at the paid tiers.

As of September 2026, here is the side-by-side breakdown:

OpenProject Basic and Professional have a 25-user minimum, so a 10-person team is billed for 25 users. Plane prices are listed in USD and OpenProject prices in EUR, following each vendor's current pricing.

The bigger difference is what each plan includes and when minimum seat requirements begin to apply.

• Plane Pro ($6/seat/month) includes the workspace Wiki, time tracking, custom Work Item Types, and Initiatives.
• Self-hosted Pro also includes SAML and OIDC SSO.
• For Plane Cloud, SSO is available on Business at $13/seat/month.

OpenProject includes SAML and OIDC SSO on its Professional plan at €10.95/user/month, with a 25-user minimum. This minimum matters for smaller teams evaluating paid plans.

OpenProject includes time tracking and budgeting in its Community features. Plane's time tracking starts on Pro at $6/seat/month.

Core work management and feature breadth

Plane covers a wider surface of modern work management, while OpenProject operates for traditional project controls.

This is where the difference between the two tools becomes most visible. OpenProject calls its core unit a "Work Package," a flexible container that can represent tasks, milestones, phases, features, bugs, risks, or user stories. The system is structured around project management with timelines, dependencies, work package hierarchies, time tracking, and costs.

Plane uses "Work Items" as its core unit, with Pro adding custom Work Item Types for bugs, features, support tickets, requests, stories, and other types of work. Work Items connect with Cycles, Modules, Milestones, Initiatives, dependencies, and the wider project context.

Plane workflows: Setting up workflows on Plane

OpenProject includes budgeting and cost reporting in its Community features, including labor costs, unit costs, budgets, and time and cost reports. This is relevant for teams that need project-level cost tracking alongside their work.

Plane keeps time tracking directly on Work Items. Team members can log time from the Work Item detail page, while admins can filter consolidated worklogs and download reports as Excel or CSV files. Business adds approval-backed worklogs for teams that need review before time entries are finalized.

Plane also gives every team five layouts, including List, Board, Calendar, Gantt, and Spreadsheet. OpenProject expanded its Community edition in v17.3 to include all Action board types, including Kanban boards. On these Action boards, moving a Work Package between columns can update the corresponding attribute automatically.

Customization and flexibility

Plane gives teams control over how their workflows, fields, and structures behave. OpenProject offers customization in some areas but gates key capabilities behind higher tiers.

Both tools support custom fields and custom work item types. That said, the customization experience differs significantly.

• Plane lets teams on Pro and above define custom work item types, so your Engineering team can track Bugs and Features while your Support team tracks Tickets and Requests, all inside the same workspace. On Business, you get trigger-condition-action automations, workflows and approvals, and Project Templates that save states, workflows, automations, and other project settings. Enterprise Grid adds multiple workflows, Granular Access Control, and custom roles.
• OpenProject supports custom work package types, custom fields, workflows, project templates, and role-based permissions in its Community features. Custom action buttons and configurable work package forms are available from Basic, while SAML and OIDC SSO start on Professional.

Plane's customization model scales from Work Item Types and custom properties on Pro to automations, approvals, and Project Templates on Business. Enterprise Grid adds custom roles, Granular Access Control, multiple workflows, and deeper governance controls.

OpenProject's Community edition includes custom fields, work package types, project templates, configurable workflows, roles and permissions, and 2FA. Paid Enterprise plans add controls such as custom action buttons and form configuration on Basic, with SAML and OIDC SSO available on Professional.

Knowledge management

Plane includes a workspace-level wiki designed for documentation across teams. OpenProject includes a project-level wiki built on basic markup, with a new real-time Documents feature.

Documentation is where the two tools' different design philosophies become most visible.

Switch between Projects and Pages in one click. Plane keeps everything organized.

Plane's Wiki is a workspace-wide documentation system with a rich-text editor, slash commands, tables, embeds, inline images, checklists, diagrams, and other content blocks. Pages support version history and restoration, while Pro adds the workspace Wiki and Page Templates. Business adds nested pages for deeper documentation hierarchies. Pages can also be exported as PDF or DOCX and published externally.

OpenProject has two documentation features. Its Wiki is organized at the project level and supports a WYSIWYG editor, page hierarchies, page history, images, tables, links, macros, and Markdown export. Its Documents module adds real-time collaborative editing directly within individual projects.

For teams currently using a separate documentation tool alongside project management, Plane's Wiki brings company-wide knowledge closer to the work itself. Project Pages, the workspace Wiki, Page Templates, nested hierarchies, external publishing, and documentation linked directly to Work Items give teams one place to maintain project and cross-team context.

Planning and tracking

Plane separates planning across Cycles, Modules, Milestones, Releases, Epics, and Initiatives, giving teams different ways to organize execution and higher-level work.

For day-to-day planning:

• Cycles handle time-boxed work such as sprints, with progress tracking and burn-down and build-up charts on Pro. Business adds auto-scheduled Cycles with optional rollover of incomplete work.
• Modules group related work around a feature, component, or theme.
• Milestones mark important checkpoints and deadlines across Work Items, Cycles, and Modules.
• Releases group work under a named version, track delivery progress, and maintain a changelog on Business+.
• Epics sit above individual Work Items and can be used as part of Plane's Work Item Type hierarchy.
• Initiatives bring work across projects together for higher-level planning and progress tracking.

OpenProject uses Backlogs for sprint planning. Since v17.3, Sprints are dedicated objects with sprint goals, boards, burndown charts, and backlog management rather than being represented through Versions. Versions remain available for roadmap and release planning.

At the strategic level, Plane uses Initiatives to connect projects, Epics, and Work Items while progress rolls up from execution. OpenProject 17.0 added Programs and Portfolios as an Enterprise Premium add-on, with Premium starting at 100 users.

OpenProject also has dedicated Gantt scheduling controls, including manual and automatic scheduling, predecessor and follower dependencies, configurable lag, baseline comparison, and multi-project timelines. Community users can compare changes since yesterday, while broader baseline periods and custom dates require Enterprise.

Integrations and extensibility

Plane connects project work with developer tools, collaboration apps, migration tools, and AI clients.

Key integrations include:

• Developer tools: GitHub, including GitHub Enterprise Server, and GitLab, including self-managed GitLab
• Collaboration and monitoring: Slack and Sentry
• Migration tools: Jira Cloud, Jira Server, Linear, Asana, ClickUp, Notion, and Confluence
• AI and developer access: MCP Server, REST APIs, OAuth apps, Python and TypeScript SDKs, and signed webhooks

GitHub supports two-way issue sync with pull request and commit linking. GitLab connects merge requests and commits to Plane Work Items. Slack can create and manage Work Items, sync threads with Plane, and use @Plane for AI-assisted actions. Sentry can create Work Items from alerts and keep resolution states in sync.

The Marketplace also includes apps such as Raycast, VS Code MCP, Claude, and Cursor.

OpenProject supports integrations with GitHub and GitLab for connecting Work Packages with development activity. It also integrates with Nextcloud for file management and XWiki for documentation linked to project work.

Its MCP Server, introduced in v17.2, connects external AI assistants to OpenProject. As of v17.8, those assistants can create and update Work Packages, add comments, and manage Work Package relations. MCP is available on Professional and above.

OpenProject also provides API v3, OAuth support, SCIM provisioning as an Enterprise add-on, and a Ruby-based plugin system for self-hosted installations.

Security and compliance

Plane supports enterprise security controls across Cloud, self-hosted, and air-gapped deployments, with additional governance controls available through Enterprise Grid.

Plane publicly states SOC 2 Type II and ISO 27001:2022 compliance, along with GDPR and CCPA compliance. For HIPAA-regulated workloads on Plane Cloud, customers processing protected health information need a signed Business Associate Agreement and must configure and use Plane in line with HIPAA requirements.

Security controls also vary by deployment:

• Cloud: SAML and OIDC SSO are available on Business+
• Self-hosted: SAML and OIDC are available on Pro+, with the customer controlling the surrounding infrastructure
• Enterprise Grid: Adds LDAP, SCIM, Granular Access Control, IdP Group Sync, and Workspace and Project Audit Logs
• Air-gapped: Runs inside the customer's isolated environment without runtime external connectivity

OpenProject focuses heavily on European data protection and GDPR compliance. Its Enterprise Cloud is available through a global AWS-hosted shard in Frankfurt and an EU shard hosted by Scaleway, where all listed subprocessors are based in the EU. OpenProject also supports SAML and OIDC SSO on Professional+, along with native TOTP and WebAuthn two-factor authentication.

Deployment and self-hosting

Both Plane and OpenProject offer self-hosted open-source editions. The self-hosting experience, however, is very different.

Plane's self-hosted installation is a one-liner:

curl -fsSL  https://prime.plane.so/install | bash

For Docker deployments, Prime CLI handles configuration, health monitoring, backups, upgrades, service management, and other administrative tasks. Plane also supports:

• Docker Compose for standard self-hosted deployments
• Kubernetes with Helm charts
• Docker Swarm
• Coolify
• Portainer

The current Docker Compose prerequisites are 2 CPU cores and 4GB RAM, with 8GB RAM recommended for production.

For organizations that require complete network isolation, Plane offers a dedicated Air-gapped Edition through Enterprise Grid, with a 100-seat minimum. Images and required artifacts are transferred into the isolated environment, licensing uses an offline license file, and Plane requires no external network connectivity at runtime.

Standard Commercial deployments use Plane's licensing service for activation and license validation.

OpenProject's self-hosted Community Edition installs via DEB/RPM packages (their recommended method) or Docker. The packaged installation is well-documented and reliable, but involves more manual steps than Plane's one-line approach.

Plane's Community Edition is AGPL-3.0 licensed, completely free, and has no seat limit. Its feature availability is aligned with Plane Cloud's Free tier, but the self-hosted Community Edition does not inherit Cloud Free's 12-user workspace limit.

OpenProject's Community Edition is also free with no user minimum or paid seat requirement.

Pricing compared

Pricing compared

Here is the current breakdown of the most relevant tiers as of September 2026.

Plane pricing from plane.so/pricing. OpenProject pricing from openproject.org/pricing.

• Plane prices shown above are billed annually. Plane's Community Edition is a separate free, AGPL-3.0 self-hosted edition with unlimited users. Plane also offers Enterprise Grid with custom pricing; fully air-gapped deployment is available on Enterprise Grid with a 100-seat minimum.
• OpenProject prices are shown in EUR as published on its pricing page. OpenProject also offers Premium at €15.95/user/month with a 100-user minimum and Corporate with custom pricing starting at 250 users.

The pricing difference becomes more noticeable once deployment and plan minimums are included. Plane Pro and Business use the same published per-seat pricing across Cloud and Commercial self-hosted deployments, although new self-hosted Commercial purchases start at 10 seats.

OpenProject Cloud can start at five users. For self-managed Enterprise deployments, Basic and Professional require at least 25 users, Premium starts at 100, and Corporate starts at 250. OpenProject Community remains free and unlimited for teams that only need the Community feature set.

For a self-hosted team below 25 users that needs capabilities beyond a free Community edition, Plane Commercial can start at 10 seats. OpenProject's paid on-premises plans start at 25.

Final notes

Plane and OpenProject solve different problems for different teams, and being honest about that distinction matters more than pretending one tool is universally better.

OpenProject focuses on structured planning, with Gantt scheduling, time and cost tracking, budgeting, BIM, and MCP access for external AI assistants.

Plane brings project execution, documentation, automation, and AI into one workspace. Every tier includes five work layouts, while Pro adds the workspace Wiki and time tracking, and Business adds automations and approvals.

Choose Plane if you want a workspace that consolidates projects, documentation, and AI across departments and deploys with minimal friction. Choose OpenProject if you need deep financial project controls, EU-native data sovereignty, or BIM integration for construction projects.

Frequently asked questions

Is Plane better than OpenProject for small teams?

For teams under 12 users, Plane's free tier includes Board views, Cycles, Modules, and AI, features that OpenProject either does not offer or locks behind paid plans. OpenProject's free Community Edition supports unlimited users but requires self-hosting and limits boards to basic manual columns without automatic attribute updates. For small teams that want quick setup and a modern editing experience, Plane is the stronger fit.

Can I migrate from OpenProject to Plane?

Plane does not currently offer a direct OpenProject importer. But teams can export data from OpenProject as CSV/XLS and import it into Plane. Plane also offers importers from Jira, Linear, Asana, and ClickUp, so if you are migrating from one of those tools, the process is straightforward.

Does Plane offer self-hosted deployment like OpenProject?

Yes. Both Plane and OpenProject offer self-hosted open-source editions. Plane installs with a single command and includes a CLI for upgrades, backups, and monitoring. Plane also offers a dedicated air-gapped edition for fully offline environments on the Enterprise tier with custom pricing. OpenProject installs via DEB/RPM packages or Docker.

Does OpenProject have AI features?

As of February 2026, OpenProject does not have any production AI features. Plane's AI system (Plane Intelligence) is in production with natural language queries, content generation, AI agents, and Slack integration.
