Plans
What Basic and Pro each include, what Pro costs, what is the same on both, and how the upgrade prompt behaves.
DiffGuardian has two plans: Basic, which is free, and Pro. A team subscription is not a third plan — it is Pro, bought per seat for an organisation. See Teams and seats.
#Basic
Free, no card required. Enough to review with DiffGuardian properly, on one repository, with a model you host yourself.
- 1 connected repository — and it must be public. Private repositories need Pro.
- 5 AI reviews per calendar month. The count resets on the first of the month.
- Locally hosted models only — Ollama and LM Studio. Cloud providers need Pro.
- AI reviews, suggested comments and PR summaries
- The full diff viewer, pull-request fetching, and reviewing uncommitted local work
- Your own code standards and a fully editable review prompt
- Dependency graphs and stack maps
#Pro
$8 per month, or $80 per year — the annual cadence is ten months' price for twelve, about $6.67 a month. Everything in Basic, plus:
| Pro feature | What it is |
|---|---|
| Unlimited repositories and AI reviews | No project cap, no monthly review meter, public or private. |
| Cloud AI providers | Anthropic, OpenAI, Google Gemini and Kimi, on your own API key. See Choosing an AI backend. |
| Analyze Project | Whole-repository Q&A with diagrams drawn from your code graph. |
| Trace It | Read a large pull request one feature at a time. |
| Ask | Question-and-answer about the pull request you are reading. |
| Explain | Select any code in the diff and get it explained in place. |
| Polish | Rewrite a draft review comment into clear, professional prose. |
| Voice | Speak your comments and questions, and have answers read back. |
| Knowledge bases | Ground answers in your own documents and vector stores. |
| MCP connections | Let a review call your own tools — Jira, Linear, Sentry and more. |
| The DiffGuardian MCP server | Expose your indexed code to Claude Code and other agents. |
#How the Pro gate behaves
Pro features are never hidden and never greyed out. They stay exactly where you expect them, and activating one on Basic opens an upgrade prompt that names the feature instead of doing nothing. You can always see what the plan buys before you buy it.
#What is the same on both plans
- Your code never reaches DiffGuardian's servers, on either plan.
- Local models are available on both, so you can run every review you are entitled to entirely on your own machine.
- Your API keys and code-host tokens stay encrypted in your operating system's credential store (the Keychain on macOS) either way.
- Nothing is deleted if a Pro subscription ends: your local index, knowledge bases and settings stay on your machine, and the Pro surfaces simply go back to prompting.
#Upgrading
Upgrade from inside the app, or from the pricing section on the site. You are taken to a hosted Stripe checkout page — DiffGuardian never sees or stores your card details. Once payment completes, your plan updates and the app picks it up on its next refresh, usually within a few seconds.
#Teams
Buying seats for an organisation gives every member Pro automatically, with no license keys to distribute. Seats cost the same as individual Pro — $8/seat/month or $80/seat/year — with a five-seat minimum. See Teams and seats.
