71 open-source projects, each checked to actually call Jev (or reproduce it). The list is maintained in MrJev/awesome-jev on GitHub; suggest a project there. GitHub stats updated Sep 18, 2026.

Chrome extension that asks Jev whether each DOM element is an ad and removes the ones that are.
irfndi/prism-liquidity-agent
Liquidity-provision agent for Meteora DLMM. Jev judges toxic flow, market stress, and mean-reversion likelihood in shadow/advisory mode only, without driving trades. Not financial advice.

Context sieve for Claude Code. Jev judges each tool result (Read, Bash, Grep output) for relevance before it enters the context window.
