Code Review
Tenki vs Ellipsis AI Code Review: Scope, Fixes, Pricing
Table of Contents
Greptile features, pricing, and how it compares to Tenki Code Reviewer.
Greptile (YC, $45.5M raised) builds a graph of your entire repository to power AI code reviews. Tenki takes a sharper approach: tightly scoped reviews focused on merge decisions, predictable flat-rate pricing, and zero noise from day one. This post breaks down how the two compare and why Tenki is the better choice for most engineering teams.
Feature Comparison
Feature | Greptile | Tenki | Tenki Advantage |
|---|---|---|---|
Review Approach | Builds and queries a full repo dependency graph | PR diff + relevant context + Custom Context markdown file you control | Explicit team control over what matters. No waiting for a learning system to converge |
Review Speed | ~3 min average per PR (graph queries add latency) | Fast PR reviews on every commit | Less time waiting on AI between iterations |
Noise Control | Reactive: suppresses comment types after ~3 ignores; 2 to 3 week ramp | Proactive: only reports issues introduced by the PR that could cause bugs, security risks, or instability AND can be addressed in the PR | Low noise from day one. Your team isn't a training set |
Review Output | Inline PR comments with suggested fixes | Structured summary: APPROVE / APPROVE with minor suggestions / CHANGES REQUESTED, plus LOW / MEDIUM / HIGH security risk rating, grouped by Security, Code Quality, Other Observations | Built around the merge decision, not a list of everything the AI noticed |
Custom Rules | Custom rules + thumbs up/down feedback loop (2 to 3 weeks to calibrate) | Custom Context markdown file committed to the repo | Configure in minutes, version-controlled with your code, no learning period |
Pricing | $30/seat/month, 50 reviews included, $1 per overage review | $20/seat/month annual ($25 monthly), unlimited repos and unlimited reviews | 33% cheaper at the headline rate, plus zero overage risk during busy months |
Cost at Scale (50 devs, 40 PRs/dev/mo) | $1,500/mo base | $1,000/mo annual | $500/mo savings, no overage exposure |
Cost at Scale (200 devs, busy month) | $6,000 to $8,000/mo with overages | $4,000/mo flat | Up to $4,000/mo savings, fully predictable |
CI/CD Integration | Review-only | Code review + GitHub Actions runners on one platform | One vendor for review and build infra. Runners cut CI cost by 50% and build time by 30% vs GitHub-hosted |
Free Tier | Free trial (credit card likely required for Cloud plan) | 7-day free trial, unlimited reviews, no credit card | Frictionless evaluation |
Self-Hosting | Available on Enterprise | Available on Enterprise | Tie |
Enterprise Support | SOC 2 reports, SSO/SAML, dedicated Slack | Multi-org support, SLAs, dedicated Slack support, custom invoicing | Real enterprise commitments including SLAs and multi-org |
Setup | GitHub App install | GitHub App install, reviews start on next PR | Tie |
Conclusion
Greptile bets that more context always produces better reviews. The bet has costs: longer review times, a 2 to 3 week noise calibration period during which your developers wade through false positives, and pricing that punishes high-volume teams with per-review overages.
Tenki wins on the dimensions that matter most for serious engineering teams:
- Better economics. $20/seat vs $30/seat, with unlimited reviews instead of 50 per seat. A 50-person team saves $500/mo. A 200-person team in a busy month saves up to $4,000/mo. And the price is predictable, so finance doesn't get surprised in feature-freeze months.
- Low noise from day one. Tenki's reviewer only flags issues introduced by the PR that could cause real problems and can be fixed in the PR. No 2 to 3 week training period. No exposing your team to false positives so the system can learn what to suppress.
- Merge-decision oriented output. Every review ends with APPROVE, APPROVE with minor suggestions, or CHANGES REQUESTED, plus a security risk rating. Your reviewers know what to do without reading the whole comment.
- One platform for review and CI. Tenki's GitHub Actions runners replace GitHub-hosted runners at 50% lower cost and 30% faster builds. Greptile doesn't touch this layer at all. For teams that care about CI spend (and most engineering orgs do), the combined savings are significant.
- Real enterprise readiness. Self-hosting, multi-org support, SLAs, custom invoicing, and dedicated Slack support are all available out of the box.
Greptile fits teams in large, deeply interconnected monorepos who specifically need cross-file dependency analysis and are willing to pay more per seat plus tolerate overage risk. Tenki fits everyone else: teams that want sharp, low-noise reviews tied to clear merge decisions, predictable pricing, and the option to consolidate code review and CI infrastructure with a single vendor.
If you're on GitLab today, Greptile is your only option between these two. For GitHub-native teams, which is the vast majority, Tenki is the better choice.
