"I used to open regex101, crontab.guru, and 3 other tabs. Now I just open DevTools. The cron builder saved me from a very embarrassing production incident."

FAQ

Common questions

Do I need an account to use the tools?
No. All tools work fully without signing up. An account lets you save patterns, share sessions, and access Pro features.
Can I pay in Bangladeshi Taka?
Yes. Bangladesh users pay via AamarPay — bKash, Nagad, Rocket, and all major BD bank cards. International users pay via Lemon Squeezy (Stripe, PayPal, Apple Pay, Google Pay). The right gateway is auto-detected.
What does Pro actually unlock?
Saved patterns and sessions across devices, early access to new tools before public launch, and priority email support. All core tool functionality is free forever.
What's included in Lifetime?
Everything in Pro, plus every tool we ship in the future — at no extra charge. It's a one-time payment with no renewals. Ever.
Will existing patterns be deleted if my Pro expires?
Your saved data is never deleted. You just lose access to Pro-only features until you renew. Everything is intact when you come back.
How is this different from regex101 or crontab.guru?
Those are great single-purpose tools. DevTools is a platform — all your daily utilities in one place, with a consistent UI, shared history, and URL-shareable state across every tool.
