Same evidence score as the ranking — GitHub stars, Hacker News mentions, release activity, free access — recomputed nightly, never sold. See all 7 tools for AI code review.
Top 3
evidence / 100
+ The underlying PR-Agent is open source and self-hostable with your own model.
− Several overlapping products make the offering confusing to adopt.
+ Tab autocomplete predicts multi-line edits across files better than any competitor.
− Usage-based pricing changes and request limits on Pro have repeatedly frustrated heavy users.
+ Deepest GitHub integration: assign an issue to Copilot and it opens a PR.
− Completions and agent lag behind Cursor and Claude Code in quality despite more models being offered.
All 6, side by side
| Tool | Score | Pricing | What you get free | Platforms |
|---|---|---|---|---|
| Qodo | 80 | Free tier | no limits published | web, vscode-extension, jetbrains-plugin, cli |
| Cursor | 62 | Free tier | Pro $20/mo | mac, windows, linux |
| GitHub Copilot | 53 | Free tier | Free tier; Pro $10/mo; Pro+ $39/mo | vscode-extension, jetbrains-plugin, cli, web |
 CodeRabbit | 26 | Free tier | Pro $24/dev/mo; free for open source | web, vscode-extension |
 Graphite | 21 | Free tier | no limits published | web, cli |
 Sourcery | 16 | Free tier | Pro $12/mo; free for open source | web, vscode-extension, jetbrains-plugin |
A free tier counts, and so does an open-source licence you can self-host — both are in the table, so a tool that is only free for a trial is not here.
