What leantime is

PHP 8.2+ application backed by MySQL 8.0+ or MariaDB 10.6+, deployable via Docker or traditional web hosting (Apache/Nginx). Includes plugin system, LDAP/OIDC authentication, S3 file storage support, and REST API.

Quickstart

Get the leantime source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/Leantime/leantime.gitcd leantime# follow the project's README for install & configuration

Best use cases

Small to mid-size teams seeking simplified project management

Leantime bridges Trello simplicity and Jira feature richness without steep learning curves, making it suitable for teams with mixed technical backgrounds or neurodivergent members.

Self-hosted deployment with regulatory or data sovereignty requirements

AGPL-3.0 license and Docker support enable full on-premise control over data. Suitable for organizations needing HIPAA, GDPR, or data-residency compliance.

Multi-language, geographically distributed teams

Support for 20+ languages, goal/strategy alignment features, and retrospective management make it practical for remote-first organizations using lean methodologies.

Implementation considerations

  • PHP 8.2+ and MySQL 8.0+ mandatory; verify host compatibility before deployment. Full extension list (bcmath, LDAP, OpenSSL, etc.) must be pre-installed.
  • Initial installation requires manual database setup and `/install` endpoint configuration; automate via Docker Compose to reduce friction.
  • LDAP/OIDC integration available but configuration detail unknown; plan for identity provider integration testing.
  • Plugin system exists but plugin ecosystem maturity and availability are not documented; validate availability of required plugins early.
  • Data migration from Jira, Asana, ClickUp, or Trello not explicitly documented; plan manual or custom ETL process.

When to avoid it — and what to weigh

  • Proprietary codebase or strong vendor lock-in preference — AGPL-3.0 requires derivative works to remain open-source; evaluate copyleft obligations before adoption in commercial proprietary products.
  • Low operational overhead desired — Self-hosted instances require MySQL/PHP infrastructure management, patching, and backups. Managed SaaS offering status is unknown from provided data.
  • Deep legacy system integrations required — Plugin/API extensibility is noted but specific integration capability (SAP, Oracle, legacy ERP) is not documented. Requires technical review.
  • Enterprise-grade SLA and 24/7 support contracts needed — Open-source project with community support model; no mention of commercial support tiers or SLAs in provided materials.

License & commercial use

Licensed under AGPL-3.0 (GNU Affero General Public License v3.0). This is a strong copyleft license requiring that any modifications or derivative works distributed remain open-source under the same terms.

AGPL-3.0 permits internal commercial use without disclosure obligations. However, if you modify Leantime and distribute it (including as a service), you must release modifications as open-source under AGPL-3.0. Carefully review copyleft implications before using in proprietary product distribution. No commercial support entity or licensing exemption mentioned in provided data; requires legal review for your use case.

Security considerations

Two-factor authentication and LDAP/OIDC support are documented. File upload handling and web server configuration (PATCH method on IIS) require attention. No security audit, CVE history, or penetration test results are mentioned in provided data. Evaluate with your security team before production deployment, especially for sensitive data.

Alternatives to consider

Jira (Atlassian)

Enterprise-grade with extensive integrations, SLA-backed support, and managed cloud option. Higher licensing cost and steeper learning curve; proprietary codebase.

Asana

SaaS-first, polished UI, strong team collaboration features. No on-premise option; higher cost; less suitable for organizations with strict data residency requirements.

OpenProject (open-source, GPL-3.0)

Open-source alternative with strong Gantt/resource planning. Different license (GPL vs. AGPL), different feature focus; requires similar self-hosting effort.

leantime FAQ

Can I use Leantime in a commercial product without releasing my code?
AGPL-3.0 allows internal commercial use. If you distribute Leantime (including as a hosted service) with modifications, you must open-source those modifications under AGPL-3.0. Consult legal counsel for your specific scenario.
Is there a managed/hosted version?
Not documented in provided data. Official leantime.io website likely has details; contact maintainers or check their website for SaaS offerings.
What databases are supported?
MySQL 8.0+ or MariaDB 10.6+. No PostgreSQL, SQL Server, or other backends mentioned.
Can I migrate data from Jira or Asana?
Not explicitly documented. Custom scripts or manual import may be required; plan migration effort early or request community guidance.
