How does DiffGuardian compare to Greptile?
Last updated October 5, 2026
DiffGuardian is a desktop app that helps you understand a pull request: it reads it against the whole repository, splits it into the features it ships, and lets you read it, hear it or see what it touches. Greptile is a hosted service that indexes a repository into a dependency graph and runs review agents against pull requests on GitHub or GitLab. Tools like that find and flag problems for you; DiffGuardian is built to keep you in the code and help you understand it quickly.
#How they compare
| DiffGuardian | Greptile | |
|---|---|---|
| Where it runs | Desktop app for macOS, Windows and Linux | Hosted service by default; Enterprise customers can self-host Greptile "bring-your-own-cloud" in their own servers or cloud environment [2] |
| Where code is sent | Your choice per job — a local model (never leaves your machine) or your own cloud AI key sent directly to the provider; DiffGuardian's servers only handle sign-in, billing and status | By default, to OpenAI and Anthropic's API platforms for inference; code is cached on Greptile's machines until access is revoked in GitHub or GitLab, then deleted. Self-hosted (Enterprise) customers' code stays on their own servers or provisioned cloud environment [2] |
| Bring your own key | Yes, for cloud providers (Anthropic, OpenAI, Google Gemini, OpenRouter) — requires Pro | Bring your own LLM (base URL and API key) is listed for self-hosted deployments [2]; self-hosting is listed under the Enterprise plan [3] |
| Local/offline models | Yes — Ollama, LM Studio, llama.cpp and vLLM, on every plan, no internet required | Self-hosting the LLM instead of using OpenAI's API is listed for self-hosted deployments [2]; self-hosting is listed under the Enterprise plan [3] |
| Git hosts supported | GitHub, GitLab, Bitbucket | GitHub and GitLab; Enterprise adds GitHub Enterprise support [1][3] |
| Review style | Guided, feature-by-feature walkthrough ordered by risk, inside the desktop app | Review comments posted on the pull request [4] |
| Pricing model | Free Basic plan; Pro and Team per seat | Starter: free, unlimited repositories, 50 credits/month, one active developer. Pro: $30 per seat per month, 50 credits per seat included, $1 per additional credit. Enterprise: custom, adds self-hosting and SSO/SAML [3] |
#Where Greptile is stronger
Greptile builds a dependency graph of the whole repository before it reviews a change and runs several review agents in parallel [1], and its Enterprise tier can run entirely inside a customer's own servers or cloud environment with a self-hosted LLM [2]. A team that specifically wants a hosted, always-on reviewer across GitHub and GitLab without installing a desktop app may prefer it for that reason.
