TryDevSnip is a free local-first developer toolkit that runs in your browser.

Format and diff JSON, explain cron schedules, convert timestamps, decode JWTs, hash, Base64, and generate UUIDs — without pasting secrets to the cloud. Processing stays in your tab.

Built by Acsaven for developers who don’t want JWTs and configs on stranger servers.
