The requirement is versioned with the code, and findings can be checked again on the repaired working file. `perch check` reads working files; `perch scan` reads Git HEAD. Relevant source is sent to TypeSafe’s hosted models. The MIT CLI does not run model inference offline. [See the rule catch a regression](https://codereviewguide.fyi/perch-vs-getcodereviews/#check)[Install the Perch CLI](https://github.com/lakeday-org/perch/blob/main/docs/install.md) ## Perch ~50¢ per mid-sized pull request · estimate - 10¢ per 1,000 fresh rule checks - Cached checks free - No seat fees · $5 free usage credit - MIT CLI · English project rules **GetCodeReviews**Pro: $29/month for 200 reviews and 3 GitHub repositories. Team: $99/month for 1,000 shared reviews and 5 members. Perch estimate: approximately 150 methods read, based on September–October 2026 check density.

A saved requirement makes a recurring mistake checkable. In this Perch capture from September 20, 2026, the same rule flags a missing guard and passes after the guard is restored. ### The regression ``` def refund(order, payment): payment.refund(order.total) order.status = "refunded" return order ``` 1 check, 1 broken. Refunded orders cannot be refunded again. ### The guarded method ``` def refund(order, payment): if order.status == "refunded": return order payment.refund(order.total) order.status = "refunded" return order ``` 1 check, nothing to report. Source: [public order-service checkout.py at the linked commit](https://github.com/lakeday-org/perch/blob/4af67af46d76ac99398d61c7ad0a45441760d4dc/test/fixtures/order-service/checkout.py). The captured standalone file is refund.py. [Perch command output and timestamp](https://codereviewguide.fyi/perch-vs-getcodereviews/refund-capture.json). This saved-rule demonstration does not measure GetCodeReviews's detection rate. ## Perch vs GetCodeReviews: what your team runs. Perch turns project behavior into focused checks that agents can run before committing. Use these differences to choose the review workflow and billing model your team needs.

Project, file and method selectors keep the requirement explicit. Team size adds no seat fee, and an unchanged requirement with unchanged inputs reuses its cached answer for free. ## Review before committing GetCodeReviews: VS Code, API, Actions and browser surfaces; standalone CLI was not verified. [GetCodeReviews workflow documentation](https://getcodereviews.com/). Perch reads the current working file with `perch check`. For a known requirement, select its rule name and method instead of requesting another broad review. A local CLI describes where the command runs; Perch sends relevant source to hosted TypeSafe models for analysis. ## How do saved requirements differ? GetCodeReviews: Team custom rules on the Team plan. [GetCodeReviews rule documentation](https://getcodereviews.com/). Perch stores English `ensure` rules in `perch.yaml` or `.perch/rules/`. Project, file and method scopes determine what is checked. Run the named check after an edit and after the repair; a rule finding can fail the command and a CI gate. [Perch rules](https://github.com/lakeday-org/perch/blob/main/docs/rules.md) · [Working-file checks](https://github.com/lakeday-org/perch/blob/main/docs/check.md). ## What does the review bill depend on? [Compare GetCodeReviews's billing unit and Perch's usage estimate](https://reviewpricing.fyi/getcodereviews/) ## Is the CLI open source and offline? GetCodeReviews: Commercial review service. [GetCodeReviews product or license source](https://getcodereviews.com/). Perch’s CLI is MIT-licensed; hosted model inference is a separate paid service included in its published check rate. It does not run the model offline. Unchanged requests can reuse cached answers for free. Fresh judgments can vary, and a passing requirement check does not prove application correctness. [Perch MIT license](https://github.com/lakeday-org/perch/blob/main/LICENSE). ## When does GetCodeReviews fit the workflow? GetCodeReviews offers editor, API, Actions and browser workflows. Review allowances and member limits affect its subscription, and a standalone CLI was not verified. ## Estimate the review bill [Perch and GetCodeReviews: pricing, allowances and workload calculator](https://reviewpricing.fyi/getcodereviews/) ## Make the agent check its next edit. ### Install the CLI ``` npm install -g @lakeday/perch ``` [Perch installation and quick start](https://github.com/lakeday-org/perch/blob/main/docs/install.md) ### Save a behavior rule ``` perch rules add refund-once \ --where refund.py --each method \ --ensure "Refunded orders cannot be refunded again." ``` The captured rule checks the requirement shown above. [Rule syntax and selectors](https://github.com/lakeday-org/perch/blob/main/docs/rules.md) ### Check the working file ``` perch check refund.py::refund --rules refund-once ``` Run the check after an edit and after the fix. [Working-tree check documentation](https://github.com/lakeday-org/perch/blob/main/docs/check.md) Use [perch scan](https://github.com/lakeday-org/perch/blob/main/docs/scan.md) for repository code at Git HEAD and [changed-code CI checks](https://github.com/lakeday-org/perch/blob/main/docs/ci.md) for pull requests. New model judgments can vary. Repeatability comes from cached answers for unchanged requests; a pass does not prove application correctness. ## Keep your project requirements checkable. Choose Perch when you want an MIT CLI, English behavior rules and usage pricing that stays independent of team size. Give your coding agent a saved check it can run after every relevant edit.
