kimai
Kimai is an open-source time tracking system for tracking work (e.g., time entries per customer/project), with billing/reports features. It can be self-hosted via web UI and exposes a backend for managing entities like activities, projects/customers, users, and time records.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
As a self-hosted web app, security depends on your deployment configuration (TLS termination, reverse proxy, cookie/session security, database hardening, and patching). Supplied content does not provide specific evidence of secret handling practices, dependency posture, or fine-grained API scopes.
⚡ Reliability
Best When
You want a self-hosted time tracking web app with reporting and configurable billing-friendly workflows.
Avoid When
You need a fully documented public API/SDK for agent-driven programmatic use, or you require no operational overhead (Kimai still needs deployment and maintenance).
Use Cases
- • Time tracking for individuals/teams (manual or structured entries)
- • Managing work by customer/project/activity categories
- • Generating reports for attendance, utilization, and timesheets
- • Invoicing/billing workflows using tracked time (depending on configuration)
- • Self-hosted alternative to SaaS time tracking tools
Not For
- • Use cases requiring a lightweight, single-purpose CLI/API-only service (Kimai is primarily a full web application)
- • Organizations that cannot self-host or manage their own instance
- • Ultra-high automation via a public developer API if you need a documented, stable API contract
Interface
Authentication
Authentication method details are not provided in the supplied content; Kimai commonly uses web app login and role-based access internally, but this evaluation cannot confirm OAuth/scopes/public API auth.
Pricing
No SaaS pricing information is provided in the supplied content; Kimai is primarily self-hosted/open-source.
Agent Metadata
Known Gotchas
- ⚠ No MCP server or agent-friendly programmatic interface is confirmed from the provided content.
- ⚠ If agents interact via the web UI, automation may be brittle (CSRF/session handling, UI changes, and lack of machine-stable contracts).
- ⚠ Time tracking systems often require careful permission scoping and correct entity IDs (projects/customers/activities), which can be error-prone without a stable API.
