2. Qodo

Free tier4.3· Free · paid from $30/user/mo

Qodo (formerly CodiumAI) covers code quality across the workflow: review and test generation in the IDE, automated pull-request review through Qodo Merge, and a CLI for agents. Its open-source PR-Agent can run reviews in your own CI. Teams pricing is around $30 per user per month, but packaging changed in mid-2026 and sources disagree on the current plan (some list a free tier and $30 seats, others a trial plus shared credits), so confirm with Qodo before budgeting.

3. Cursor Bugbot

4.4· Usage-based

Bugbot reviews GitHub pull requests with Cursor's agent and focuses on logic bugs and security issues rather than style, which keeps false positives low. Findings link straight back into the Cursor editor to fix. Since June 2026 it is usage-based, at roughly $1.00 to $1.50 per PR review drawn from your Cursor plan usage, so cost tracks how often you merge rather than how many seats you have (as of September 2026).
