Production-grade tools for production-grade data
You handle PII, production JWTs, client credentials, and internal schemas every day. Most online dev tools send that data to a server. Septim Forge processes everything in your browser — nothing is ever transmitted.
Problems you already have
Your team pastes production JWTs into random sites
Septim Forge decodes them locally. The token never leaves your browser — no network request, no server log, no third-party analytics pixel watching.
Your SQL queries contain real table names and schemas
Format and beautify SQL without exposing your database structure. Everything runs in-browser via JavaScript — we literally cannot see your queries.
Your config files have secrets
Diff two configs side-by-side to catch what changed before a deploy. Environment variables, API keys, connection strings — none of it leaves your machine.
