## Greptile

* **What it is.** "AI agents that review and test pull requests with full context of the codebase." ([greptile.com](https://www.greptile.com/))
* **Trigger model.** PR comments on GitHub/GitLab; IDE integrations with Claude Code, Cursor, Codex, Devin; MCP connection; a `/greploop` command for iterative workflows. ([greptile.com](https://www.greptile.com/))
* **Where it runs.** Both SaaS and self-hosted (self-hosting in AWS is available on the Enterprise plan). ([greptile.com/pricing](https://www.greptile.com/pricing))
* **LLM flexibility.** Cloud plan uses Greptile's managed stack. Enterprise self-host can deploy with their own LLM providers.
* **Open source.** Proprietary / closed source.
* **Agent architecture.** "A swarm of agents" operating in parallel; codebase indexed as a graph; dedicated TREX agent for autonomous test generation. ([greptile.com](https://www.greptile.com/))
* **Key claims.** Graph-based codebase indexing, learning from team PR comments, plain-English custom rules, multi-file logical bug detection, MCP integration with coding agents.
* **Pricing.** Cloud $30/seat/month with 50 reviews included + $1 per additional review; unlimited repos and users. Enterprise custom pricing adds self-hosting, SSO/SAML, custom DPA, and a forward-deployed engineer. No free tier; OSS and startup discounts available. ([greptile.com/pricing](https://www.greptile.com/pricing))
* **Data handling.** Retention/training posture not publicly documented on pages fetched. Custom DPA offered on Enterprise.

## Where MergeWatch differs

* **Self-host without an Enterprise contract.** MergeWatch self-hosting works with `docker-compose up` on any cloud or VPS. Greptile's self-hosting is Enterprise-tier only and runs in AWS.
* **Fully open-source review pipeline.** AGPL-3.0 across prompts, orchestrator, and templates. Greptile's review logic is closed — you cannot audit the agent behavior.
* **Pricing model.** MergeWatch has no per-seat charge. On Greptile Cloud you pay $30 per seat + $1 per review above 50; on a busy repo this compounds quickly.
* **Pluggable LLM on SaaS.** MergeWatch SaaS runs on Bedrock; self-hosted supports four providers out of the box. Greptile's non-Enterprise tier uses Greptile's managed stack only.
* **Merge-readiness score.** MergeWatch produces a 1–5 composite score. Greptile does not publicly document an equivalent signal.
* **Agent-authored PR detection.** MergeWatch flags PRs from coding agents and tightens the review prompt. Greptile does not publicly document this.

## When Greptile might be the better fit

* You want a graph-indexed full-codebase context layer for cross-file logical-bug detection and are willing to trust a closed index.
* You have a flat, low-review-volume repo where $30/seat + $1/review is cheaper than paying LLM tokens directly.
* You specifically want the `/greploop` iterative workflow or the TREX test-generation agent — both are Greptile-native behaviors.
* You're on GitLab and need a batteries-included PR-review integration.
