Wispbit - Linter for AI Coding Agents

TL;DR

TL;DR: Wispbit is an open-source, model-agnostic linter that runs AI code reviews against rules you define, catching standards violations before they land in your codebase.

What Is Wispbit?

Wispbit is a free, open-source CLI tool that runs AI-powered code reviews against your codebase using rules you define. Unlike code editors (Cursor, Claude Code, Cline) which are optimized for writing code, Wispbit is a specialized tool for reviewing it. The project is MIT-licensed with 119 stars on GitHub as of February 2026.

The core idea: when everyone on a team uses a different AI tool to write code, standards drift. Wispbit gives you one central place to define what “good code” means for your project, and enforces those rules on every review.

Key features

• Model-agnostic — works with any LLM provider (Claude, GPT, Gemini, etc.)
• Runs anywhere — CLI, GitHub Actions, background agents, MCP
• Your rules, your data — no vendor lock-in, you own the prompts and data
• Opinionated output — no summaries or poems; just violations with actionable feedback
• Rules directory — free, community-contributed rules at wispbit.com/rules

Setup Workflow

Step 1: Install

npx @wispbit/cli@latest configure

Step 2: Configure your rules

After installation, configure your ruleset:

npx @wispbit/cli@latest review --rules ./my-rules/

Rules are plain-text files that define what to check. The rules page hosts free, community-contributed rules for common standards.

Step 3: Run a review

npx @wispbit/cli@latest review

The CLI will invoke your configured LLM provider and report any violations against your rules.

Step 4: Integrate with CI

Wispbit ships with a GitHub Actions integration. Add it to your workflow to block PRs that violate team standards:

- name: Run Wispbit review
  run: npx @wispbit/cli@latest review
  env:
    WISPBIT_API_KEY: ${{ secrets.WISPBIT_API_KEY }}

How It Works

Wispbit separates the concerns of writing and reviewing code. Writing tools are optimized to generate code quickly; review tools need to evaluate quality against a specific standard. By decoupling them, Wispbit says it reduces noise and improves accuracy compared to asking a general-purpose AI to do both.

The tool is provider-agnostic — it does not care which LLM you use, as long as you point it at an API endpoint with a compatible interface. This makes it portable across teams with different LLM preferences or cost constraints.

Comparison with Similar Tools

Wispbit distinguishes itself from Bugbot, Copilot, CodeRabbit, and Greptile in several ways:

| Feature | Wispbit | Others | |---|---|---| | Open source | Yes (MIT) | Varies | | Runs anywhere | Yes | Often cloud-only | | Own your data | Yes | Usually hosted | | Specialized for review | Yes | General-purpose | | Community rules directory | Yes | No |

FAQ

Q: How is this different from asking a code editor AI to review code? A: Writing and reviewing code require different prompts and tooling. Wispbit is purpose-built for review, which its maintainers say produces more accurate, lower-noise results. It also provides a centralized ruleset that applies consistently regardless of which tool each developer uses to write code.

Q: Does it require a paid API key? A: Wispbit itself is free and open-source. You supply your own LLM API key for the provider of your choice. Some providers offer free tiers that work with Wispbit.

Q: Can I self-host it? A: Yes. Wispbit runs as a CLI tool and does not require Wispbit’s infrastructure. Point it at any LLM endpoint you control.

Q: What languages are supported? A: Wispbit is language-agnostic. The review quality depends on the rules you configure and the LLM you use.

Conclusion

Wispbit fills a specific gap: keeping AI-assisted code consistent with team standards when different developers use different AI tools. By separating the review concern from the writing concern and making rules portable and open-source, it gives teams a lightweight path to enforced code quality without vendor lock-in.

If you want to try it, start with the two-command installation:

npx @wispbit/cli@latest configure
npx @wispbit/cli@latest review

Then browse wispbit.com/rules for community rules that match your stack.
