Diffwise vs Graphite
Graphite is code review platform built around stacked pull requests, with an AI reviewer (formerly Diamond) folded into the Graphite Agent; acquired by Cursor in late 2025. Diffwise takes a different approach: a team of 40+ specialist AI agents (security, performance, conventions, language-specific) reviews every pull request in parallel, classifies findings as Fixed, Still Open, or New on each push, and tracks anti-patterns across your entire organization.
The short version: pick Diffwise for specialist multi-agent review, cross-repo intelligence, and flat-rate pricing that does not grow with headcount. Pick Graphite if stacked PRs are the workflow change you actually want, with AI review as a bundled extra.
Side-by-side comparison
| Dimension | Diffwise | Graphite |
|---|---|---|
| Review architecture | 40+ specialist agents in parallel (security, performance, conventions, language-specific) | Single AI reviewer bundled with stacked-PR platform |
| Incremental re-review | Every push: findings classified Fixed / Still Open / New, old comments collapsed | Reviews stack updates; no finding-state classification |
| Cross-repo intelligence | Anti-pattern tracking across all repos, hot file analysis, resolution velocity | PR analytics; no cross-repo anti-pattern tracking |
| Custom rules | Custom Agent Builder + .diffwise.yml config-as-code | Custom rules and style enforcement |
| Pricing model | Flat-rate: $19/mo managed or $9/mo BYOK (OpenRouter) — not per-seat | Per-seat: $20-40/user/mo (unlimited AI reviews on Team) |
| Free tier (private repos) | 50 reviews/mo, 3 repos, free forever, no credit card | Free for individuals |
| Code storage | Zero — diff processed in memory, discarded after review | Vendor-managed |
| Platforms | GitHub | GitHub |
Where Graphite shines
- Unique stacked-PR workflow plus AI review combo
- Low false-positive rate reported by users
- Traction with name-brand engineering orgs
- Cursor acquisition brings frontier-model resources
Where Graphite falls short
- Ranked low for bug detection in Martian's benchmark (few false positives but missed most critical bugs)
- Stacked workflow creates lock-in; breaks down when teammates don't use Graphite
- AI review no longer sold standalone; unlimited reviews need the $40/user/mo Team plan
- Product in post-acquisition transition; roadmap unsettled
Why teams choose Diffwise
- Specialists, not a generalist. 40+ agents each scoped to one concern: a security agent hunting injection and auth bypass, a performance agent hunting N+1 queries, language agents that activate per file type.
- Re-reviews that respect your time. On every push, findings are classified Fixed, Still Open, or New. No re-reading walls of repeated comments.
- Cross-repo intelligence. Anti-patterns tracked across your whole org, hot file analysis, and resolution velocity metrics in one dashboard.
- Flat pricing. $19/mo managed or $9/mo BYOK, whether you have 3 engineers or 30. Free tier: 50 reviews/month, 3 repos, no credit card.
- Zero code storage. The diff is processed in memory and discarded.
Frequently asked questions
What is the main difference between Diffwise and Graphite?

Graphite: Code review platform built around stacked pull requests, with an AI reviewer (formerly Diamond) folded into the Graphite Agent; acquired by Cursor in late 2025.
Is Diffwise cheaper than Graphite?
Diffwise is flat-rate ($19/mo managed or $9/mo with your own OpenRouter key) regardless of team size, with a free tier of 50 reviews/month on 3 repos. Graphite pricing: Free for individuals; Starter $20/user/mo; Team $40/user/mo with unlimited AI reviews; 30-day trial.
When is Graphite the better choice?
Stacked PRs are the workflow change you actually want, with AI review as a bundled extra.
Does Diffwise store my code?
No. Diffwise processes the diff in memory and discards it after the review. Zero bytes of code are persisted; only findings are stored for tracking.
