Why people look for alternatives to perch
The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.
- Almost no independent user reviews or testimonials exist for the actual linter.
- Open language-filtering bug means shipped scans may flag irrelevant vulnerability classes.
- No listed integrations with CI/CD, editors, or Slack — everything is manual CLI wiring.
- Name collision with Google Perch and a board game makes community support hard to find.

In fairness: users also consistently praise free and globally installed via npm as @lakeday/perch — zero cost to try, and natural-language rules in perch.yaml let you encode team conventions as reviewable code. A complaint list is not a verdict — see the full picture on the perch page.
