CodeUtil.dev is a collection of 20+ browser-based developer tools. JSON formatter & validator, regex tester, cron expression generator, Base64 encoder/decoder, JWT debugger, URL parser, hash generator, and more. Everything runs client-side โ no data leaves your browser. No sign-up needed, just open and use.
AI coding agents waste most of their context window grepping files and guessing at code structure. Constellation gives them a persistent, team-wide knowledge graph of your codebase (symbol search, dependency graphs, impact analysis) delivered via MCP so every token goes toward reasoning, not discovery.
