DevTools by Hakeemify
16 developer tools.
One tab. One price.
Sixteen essential developer utilities in one fast, ad-free, browser-based suite — with local-first privacy and Bangladesh-friendly pricing.
One tab, sixteen tools
Stop hopping between a dozen ad-heavy single-purpose sites.

Free core, or $79 lifetime — no creeping subscriptions.

Questions
Is it really free?
Yes — the core of all ten tools is free with no card. Pro ($4/mo/$34/yr/$79 once) adds saving to your dashboard and power features.
Which payment methods work?
Card payments in USD, plus local methods — bKash, Nagad and Rocket — detected automatically.
Is a subscription required?
No. There's a monthly and yearly plan if you want them, but $79 once buys lifetime access — pay once, own forever.
Is my data private?
Tools like HashLab run entirely in your browser. Your account is only used to save your work when you opt in with Pro.
Do I need to install anything?
No. Everything runs in the browser — open a tab and go.
