CodeRabbit alternative — build your own PR review agent
CodeRabbit is a polished per-seat SaaS for AI pull-request review. If you'd rather own the workflow — choose the model, tune the prompts, pay per token instead of per seat — a review agent on CompanyFabric is a template away.
Side by side
CodeRabbit vs the open path
| CodeRabbit | CompanyFabric | |
|---|---|---|
| Pricing model | Per seat, per month | Per token — pay for reviews that actually run |
| Model choice | Theirs | Any model in the library; swap with one line |
| Prompts & rules | Configurable within their product | Yours entirely — it's your agent |
| Data path | Your diffs through their service | Your infra + one metered API call |
| Setup | Install GitHub app | Deploy the starter template, add a key |
How it works
The CompanyFabric way
Start from the PR-review starter template: a GitHub Action that sends the diff to any model behind api.companyfabric.com and posts the review. Route small diffs to a cheap tier and risky ones to a frontier model — the split is a config line, and the bill is exactly the tokens used.
FAQ
Frequently asked questions
Is per-token really cheaper than per-seat?
For most teams, yes — review volume is spiky, and seats price for the peak. Metered pricing charges for actual reviews; a 20-developer team typically pays a fraction of seat pricing.
How long does the template take to set up?
Under ten minutes: fork the template, add COMPANYFABRIC_API_KEY as a repo secret, and open a test PR.
One key. Every model. Exact prices.
