Open-source self-hostable trackers

Trackers that can be run on your own servers, with community or official MCP servers that also reach self-hosted instances.

Where they are stronger today:

• open-source licences;
• community extensions;
• wiki-style pages;
• broader integrations.

Where Quasar differs:

• Isolation by the database. Tenant isolation is enforced by row-level security and tested against a real database in every release.
• An MCP server built into the product, designed around workflow-sized tools and explanatory refusals rather than a wrapper over the REST API.
• Agent accountability: verified plans, measured work sessions and automatic agent marks.
• Client delivery, as above.
