PR-Agent vs Tabby

Short answer

PR-Agent: Open-source AI pull-request reviewer that comments and answers questions on PRs. Tabby: Self-hosted AI coding assistant (Copilot alternative) for your team. Both are in our Coding assistants category.

Choose PR-Agent if you want: no GPU server needed and fewer license conditions (Permissive vs Open core).

Choose Tabby if you want: larger community (33.9k vs 13.6k GitHub stars).

PR-Agent publishes no official RAM figure, so we cannot compare hosting cost directly.
