The developer workspace that loads before you finish pasting.
TypeParser is a free, local-only collection of 99+ utilities for everyday engineering work — built for speed, built for privacy.
Why we built it
Every developer keeps a list of "the JSON formatter I use", "the base64 site that doesn't have ads", "the cron parser that actually explains the expression". The list grows. Each tool is a tab. Each tab loads a different ad stack, telemetry pipeline, and surprise paywall. TypeParser replaces the list with one workspace: paste anywhere, the right tool opens instantly.
Local-first, always
Every parser, formatter, encoder, and generator runs in your browser. Your JSON, JWT, secrets, and CSV never reach our servers because there are no servers handling that data. Hash a password locally. Decode a JWT from production locally. The site itself is a static bundle on a CDN.
Sub-second by design
The homepage Omni-Box detects what you paste in milliseconds and routes you to the right tool. JSON, JWT, UUID, CIDR, hex color, base64, cron — all recognized without round-trips. Tools open as separate static pages so navigation is instant, indexable, and survives a flaky connection.
No ads, no telemetry of inputs
We use anonymized Google Analytics for page-level traffic only. We never log the content you paste. We do not sell data. We do not run retargeting trackers. The free tier is the only tier.
