Best use cases
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.
DEV.co evaluation signals
Editorial assessment — not user reviews. Directional, with an explicit confidence level.
| Signal | Assessment |
|---|---|
| Maintenance | Active |
| Documentation | Adequate |
| License clarity | Clear |
| Deployment complexity | Moderate |
| DEV.co fit | Good |
| Assessment confidence | High |
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.

From evaluation to production software
Bringing leantime into production usually means new services, new interfaces, and new failure modes. DEV.co is a software development agency that builds all three and stays on for the open-source databases maintenance.
