Diffwise vs Greptile
Greptile is aI code review agent that indexes your whole codebase into a dependency graph and reviews PRs with full-repo context, posting few, high-signal comments. 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 Greptile if deep whole-codebase context on a large monorepo matters more to you than price or a free tier.
Side-by-side comparison
| Dimension | Diffwise | Greptile |
|---|---|---|
| Review architecture | 40+ specialist agents in parallel (security, performance, conventions, language-specific) | Single agent with full-codebase index and dependency graph |
| Incremental re-review | Every push: findings classified Fixed / Still Open / New, old comments collapsed | Reviews subsequent pushes; no Fixed/Still Open/New classification |
| Cross-repo intelligence | Anti-pattern tracking across all repos, hot file analysis, resolution velocity | Deep single-repo context; no cross-repo anti-pattern tracking |
| Custom rules | Custom Agent Builder + .diffwise.yml config-as-code | Natural-language rules and style guides |
| Pricing model | Flat-rate: $19/mo managed or $9/mo BYOK (OpenRouter) — not per-seat | Per-seat + usage: $30/seat/mo, then $1 per review past 50/seat |
| Free tier (private repos) | 50 reviews/mo, 3 repos, free forever, no credit card | None (open source only) |
| Code storage | Zero — diff processed in memory, discarded after review | Indexes your codebase to build its context graph |
| Platforms | GitHub | GitHub, GitLab |
Where Greptile shines
- Strong bug catch rate in independent benchmarks
- Codebase-wide context catches cross-file issues diff-only tools miss
- High signal-to-noise review philosophy
- Enterprise-grade security posture
Where Greptile falls short
- 2026 per-review overage pricing ($1/review past 50 per seat) drew heavy criticism on Hacker News
- No free tier for private repositories
- $30/seat/mo base is among the most expensive in the category
- GitHub and GitLab only — no Bitbucket or Azure DevOps
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.
