Quick start
Requires Node.js 20 or newer. From your app's project root:
npx -y [email protected] check
- In a terminal or CI:
npx -y [email protected] check - For coding agents:
npx -y [email protected] --agent-mode - Windows PowerShell: use
npx.cmdifnpxis blocked by the execution policy.
It reads supabase/migrations, your client and server code, package.json and .env.example. It does not connect to your Supabase project or send requests to your app. It exits 1 when it finds a blocker, so it also works as a CI step.
What it checks
Two other Security Advisor lints come up often in the same apps. VibeRaven has no rule for them yet, and the guides explain the fix:
security_definer_view: what it means and how to fix itfunction_search_path_mutable: what it means and how to fix it
For a before-and-after run on one migration, see the missing-RLS example.
Example output
From viberaven check 1.6.12 on a synthetic Next.js + Supabase app with one of each gap (project path shortened):
viberaven check · ~/my-app
🔴 No RLS policy proof in migrations (rls_disabled)
1 public table without row level security: public.profiles (supabase/migrations/20260301000000_init.sql:1). The Data API does not enforce row restrictions for roles and operations allowed by the table's grants. Verify those grants to determine who can read or change rows.
🔴 A policy lets anyone write every row (rls_policy_allows_all_write)
Policy "orders are editable" on public.orders (supabase/migrations/20260301000000_init.sql:13) lets anyone, signed in or not, update every row, to any values: using (true).
🔴 Service role key used in client code (service_role_key_in_client_code)
app/admin/page.tsx:4: creates a Supabase client with the service role key. This file ships to the browser, and the service role key skips RLS entirely. Move the call behind a server route or edge function and rotate the key.
🟡 Supabase connection is not using the pooler port (pooler_port_mismatch)
Found direct 5432 DATABASE_URL/POSTGRES_URL evidence. Vercel/serverless deployments should prefer Supabase transaction pooler port 6543.
🟡 Security definer function callable by the Data API roles (security_definer_function_executable)
public.grant_credits(uuid, integer) at supabase/migrations/20260301000000_init.sql:15 is security definer, so it runs with its owner's rights and RLS does not limit what it touches. No migration revokes EXECUTE from public, anon, authenticated, so anyone holding the anon key can call it at /rest/v1/rpc/grant_credits. If only the server calls it, add: revoke execute on function public.grant_credits(uuid, integer) from public, anon, authenticated; Fix: revoke execute on function public.grant_credits(uuid, integer) from public, anon, authenticated;
🟡 Stripe webhook does not verify the signature (unverified_stripe_webhook)
1 Stripe webhook handler without signature verification over the raw body: app/api/stripe/webhook/route.ts (no signature check (constructEvent), no stripe-signature header, no raw body). Anyone who finds the URL can post a fake event, for example a paid checkout.
🟡 Env vars used in code but missing from .env.example (env_var_drift)
Code reads 1 environment variable that .env.example does not document (NEXT_PUBLIC_SUPABASE_SERVICE_ROLE_KEY). Fresh clones, CI, and the production deploy can silently run without them.
🟡 Database queries with no row limit (unbounded_query)
1 file run Supabase selects or Prisma findMany with no .limit()/.range()/take bound (app\admin\page.tsx). These work with 50 test rows and melt with 50,000 production rows.
⚪ No error monitoring detected (missing_monitoring)
No Sentry/PostHog (or similar) instrumentation was found. Production errors will only surface when users complain.
Verdict: ❌ 3 blockers, 5 warnings · score 5
Fix: viberaven fix · Details: ~/my-app\.viberaven\agent-tasklist.md
Every result also lands in .viberaven/ as markdown and JSON (agent-tasklist.md, gate-result.json, context-map.json), so a coding agent and your git history can read it.
When to use it, and when not to
Use it:
- before you launch or hand off a Vercel + Supabase app built with Lovable, Bolt, Cursor, Claude Code or Codex;
- after a Supabase migration or a policy change;
- when a production error points at RLS, the service_role key, env vars, the database connection or a Stripe webhook;
- on every push or pull request, through the GitHub Action below.
It is not the right tool when:
- You need to know what is live in the database. VibeRaven is a repository check, not a live database test. It reads migrations, so it cannot see a policy someone added in the Supabase dashboard. Use Supabase Security Advisor for the live project.
- You need a full security audit. It does not send requests to your app, test for XSS or CSRF, or look up dependency CVEs. A clear result is not a security audit.
- You need to know the app works. It does not run your build or click through your pages. Use Playwright or your own tests.
- The app does not use Supabase. Most of the checks have nothing to read.
How it compares
These tools answer different questions, and most launches need more than one of them.
Data: 512 public Lovable apps
We ran the check on the Supabase migrations of 512 public Lovable repos. From the write-up:
In a static read of 512 public Lovable projects on GitHub with a supabase/migrations folder (October 2026), 47.3% (242) define at least one security definer function in the public schema that a signed-out caller with the anon key can run at /rest/v1/rpc.
The post has the method, the limits and the fix. An earlier post covers RLS policies in the same 512 apps.
Fix the gaps
npx -y [email protected] fix # list gaps with safe automatic recipes
npx -y [email protected] fix --gap <id> --dry-run # preview one recipe
npx -y [email protected] fix --gap <id> # apply it
npx -y [email protected] audit --vercel-supabase # RLS in migrations, pooler port, service_role key
npx -y [email protected] --strict # the verdict as an exit code for CI (exit 1 on not_clear; warnings exit 0)
The rls_disabled recipe adds a migration that enables RLS without policies, so browser reads return no rows until you add policies. Agree before applying it, then apply and test it through your database workflow.
In CI: the GitHub Action
Lovable and Bolt push straight to main, so a pull request check alone misses most of their changes. The VibeRaven GitHub Action runs the same check on pull requests and on pushes, in your own runner:
on:
push:
branches: [main]
pull_request:
permissions:
contents: write
pull-requests: write
jobs:
check:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v5
with:
fetch-depth: 0
- uses: ohad6k/viberaven-action@v1
A pull request gets one comment with what the change added or fixed. A push to main gets a commit comment when there is a blocker. It is advice by default; with fail-on-blockers: 'true' the job fails when it finds a blocker, and your branch protection decides what that means for merging. npx -y [email protected] init --github writes a pull-request-only version of this workflow without the Action.
Install for AI agents
Give coding agents the same context before they patch the repo:
npx -y [email protected] init --agents all --dry-run # preview
npx -y [email protected] init --agents all
npx -y [email protected] doctor --agents
This installs bounded rules (...) into:
AGENTS.md,CLAUDE.md,GEMINI.md.cursor/rules/viberaven-core.mdc(plus scoped Supabase, deploy, and payments rules).github/copilot-instructions.md.viberaven/agent-context.md,.viberaven/mission-map.md
The rules say when a pass helps (an AI-built app on Vercel + Supabase, before launch or handoff, or after a migration or policy change) and teach the loop: check, read .viberaven/, fix one gap, then check again once per batch of fixes. They are advice, not a gate: the user decides when to ship.
Agent skills
Six skills.sh skills route agents through architecture questions, version evidence, and launch proof:
npx -y [email protected] add ohad6k/VibeRaven --skill viberaven
See agent-skills/ for the full pack.
This repo also works as an agent plugin: plugin.yaml, .claude-plugin/, .codex-plugin/, and gemini-extension.json expose the six skills plus /viberaven-work, /viberaven-help, /viberaven-production-context, and /viberaven-launch commands to Claude Code, Codex, and Gemini CLI.
For a smaller install, plugins/viberaven is a standalone plugin for Claude Code and Cursor: one skill that says when a pre-launch pass fits a Vercel + Supabase app, plus a version-pinned MCP server. Its manifests specify the package version; the plugin release is separate from the quick start above.
MCP
VibeRaven is listed in the MCP registry for agents that prefer tools over terminal commands:
{ "viberaven": { "command": "npx", "args": ["-y", "@viberaven/[email protected]"] } }
Key tools: viberaven_check_readiness (runs the local check), viberaven_heal_apply, viberaven_verify, viberaven_audit, viberaven_gate_result, and viberaven_validate_npm_package (run it before adding npm dependencies).
The local Studio
npx -y [email protected] with no command opens the Studio: a local page where your own coding agent (Claude Code, Codex or Gemini CLI) makes a change in your folder, and you see the steps, your checks, the running app and the diff, with Undo one click away.
Your first app change
The same workflow, fully local, with no account:
- Open your project. Run
npx -y [email protected]in its folder. The Studio opens in your browser. - Connect your agent. Open Agents, select your installed CLI, run Test connection, then choose Use this agent.
- Show your app. Choose Show my app to start its development server.
- Ask for a small change. Pick Ask to get a plan without edits, or Edit to let the agent change files, then select Make the change.
- Check the result. Try the running app, read the check results and open Review for the diff. Missing tests are reported as unchecked; a page that loads does not prove every feature works.
On Windows PowerShell, use npx.cmd if execution policy blocks npx.
The Studio also runs on viberaven.dev: sign in with Google, bring your repo, and connect your computer once. Your agent still works on your computer. The site includes 2 free changes, then Pro for 300 changes a month. Both need a coding agent you are signed in to; its own account and limits apply.
Checks and accounts
- Local Studio and repository checks. These run on your machine without a VibeRaven account. The CLI has no telemetry.
- Changes from viberaven.dev. Sign in with Google. Free includes 2 changes per account; Pro includes 300 a month. Your coding agent's account and usage are separate. The site stores requests, progress, check results, file paths and redacted, size-limited diffs so you can review them.
- Hosted full checks. Optional: 2 on Free, 50 a month on Pro, separate from changes.
- Markdown on disk. All context lives in
.viberaven/as plain files that your agent and your git history can read. - Evidence over vibes. Findings point at repo evidence. Provider dashboard state is never claimed from repo edits alone.
- Changes under your control. Review the plan and access mode before the agent edits your project. Cleanup is plan-only. A clear repository check is not a security audit or proof that the deployed app works.
Contributing
Contributions are welcome, and most of them need no private source access:
- Read the contribution guide for repo structure, PR expectations, and local checks.
- Pick up a good first issue: docs, provider fixtures, examples, and translations.
- Share ideas or questions in Discussions.
- Join the Discord to talk to the maintainer directly.
