JevRLS
Paste Supabase pg_policies output and compare Jev, GPT, and Gemini on the same RLS leak rubric with latency and cost side by side.
by @CarolMonroe
Overview
JevRLS (jevrls.lovable.app) accepts pasted pg_policies output and scores each policy for leaks. Carol Monroe's showcase runs Jev beside GPT and Gemini with the same decision rule, surfacing who flags issues, latency, and cost together.
Problem: Supabase Row Level Security policies are easy to miswrite and expensive to audit with a full LLM call per policy line.
Built for: Supabase developers and security reviewers who want side-by-side model comparisons on the same RLS rubric.

“Paste your @supabase RLS policies and watch Jev race gpt and gemini on them. Same rubric, same decision rule, side by side: who flags the leaks, how fast, at what cost.”
How Jev is used
- Role in the product flow
- Per-policy security verdict on pasted Supabase RLS text
- Primitives
- Choice
- State in
- pg_policies style policy dump pasted into the Lovable app.
- Decision out
- Plain-words verdict per policy; site meta cites about one second per policy with Jev (marketing copy on jevrls.lovable.app).
- Paste policies into JevRLS
- Run identical rubric across Jev, GPT, and Gemini
- Compare leak flags, latency, and cost columns
Carol's demo is a benchmarking UI, not a hosted database scanner. Jev handles the fast structured judgment while GPT and Gemini run under the same decision rule so differences show up in flags and price, not prompt hacks. Treat Lovable deployment as the product home until a repo is published separately.

FAQ
- Does JevRLS connect to my Supabase project?
- The public app evaluates pasted policy text. It does not require live database credentials in the showcase flow Carol described.
- Which primitives does Jev use?
- Carol's clip describes leak flags on a shared rubric; site marketing cites fast per-policy verdicts. Treat outputs as structured policy judgments rather than free-form essays.
