For the past few weeks I've been building DevCrate — a suite of developer
tools that run 100% in your browser. No login, no ads, no data leaving
your machine.
Why I built it
I kept switching between tabs every time I needed to format JSON, decode
a JWT, or test a regex. Most tools either had ads, required an account,
or I wasn't sure what they were doing with my data. So I built my own.
What's live
- REST Client — send HTTP requests and inspect responses
- JSON Transformer — format, minify, convert to YAML/CSV
- JWT Debugger — decode and inspect tokens
- Regex Studio — live match highlighting with flag toggles
- SQL Formatter — supports PostgreSQL, MySQL, SQLite, BigQuery
- WebSocket Tester — connect, send, inspect frames in real time
- Base64 / Hash — encode, decode, MD5, SHA-256
- Cron Builder — visual editor with human-readable output
- URL Inspector — parse, encode, decode URLs
- Diff Tool — compare text and JSON line by line
- Timestamp Converter — Unix to date and back, with timezones
- HTML Formatter — format and minify HTML
Everything runs in your browser
No server ever sees your tokens, queries, or payloads. This matters when
you're working with production data and don't want it going through a
random third-party server.
We're always improving
DevCrate is actively being developed. New tools are shipping regularly,
existing ones are getting smarter, and the roadmap is public at
devcrate.net/roadmap so you can see exactly what's coming next.
If there's a tool missing from your workflow, a bug you've spotted, or
just something that could work better — we genuinely want to hear from
you. Drop a comment below or reach out directly at hello@devcrate.net.
Every message gets read.
It's free to start
Core usage is free forever. There's a Pro plan for power users who need
higher limits and saved configurations.
Check it out at devcrate.net and let us know
what you think — we're building this for developers like you and your
feedback directly shapes what gets built next.
