@abhilaksh_arora That much!! tools in single web app. Now, I do not have to scroll different different websites for these tools.
Thanks man.
@rohitnirban That's exactly why I built it! No more tab switching between 10 different sites. Glad it helps 🙏
How do you handle really large files like massive JSON payloads, does it still stay snappy or does the browser start to choke at a certain size?
@aysunvcyf Great question! Since everything runs in the browser, performance depends on the device — but for most JSON payloads (even a few MB) it stays snappy. For truly massive files (50MB+) the browser can slow down, which is a known limitation of the client-side approach. Working on adding Web Workers for heavy processing so the main thread never blocks. Will keep you posted!
How do you handle tools that usually need to call an external API, like an OpenAPI tester or anything that hits a real endpoint, since everything runs purely client-side?
@glayalatala1n3 Really good point. Tools that need to hit a real endpoint (like an API tester) are the one exception to the zero-server-calls rule — those requests have to go somewhere by nature. For those tools specifically, the request goes directly from your browser to the target API — DevTab itself never sees it. So still no middleman, just a different trust model. OpenAPI tester is on the roadmap — will make sure this is clearly communicated when it ships!
How do you keep all 110 tools updated when browser standards or new dev formats shift, and is there any plan to add team sharing or sync for saved snippets?
@melikev5mg Great question! Since all tools are pure client-side JS/TS, updates are just code deploys —
no backend migrations or data sync needed. Browser standards shift slowly enough that keeping up is manageable, and I'm the only one maintaining it right now so I can move fast. Team sharing and saved snippets are 100% on the roadmap — planning a Pro tier where you can save workflows, pin favourite tools, and share sessions with your team. No ETA yet but it's coming.
If there's a specific format or standard you're worried about becoming outdated, drop it here — happy to prioritise it 🙏
would love a way to save my frequently used tools as a custom sidebar, plus maybe a quick keyboard shortcut to jump between tools. also adding a dark/light theme toggle would be nice since some of these visual tools are easier on the eyes in dark mode
@idem1v1s Love all three of these! Dark/light theme toggle is actually already there — check the top right corner 🙂 ⌘K keyboard shortcut to jump between tools is coming in the next release. Custom sidebar with pinned/favourite tools is a great shout — adding it to the roadmap. Thanks for the detailed feedback Çiğdem, this is exactly the kind of thing that shapes what gets built next 🙏
Been looking for a quick JWT decoder without the usual upload-to-server nonsense, and this nailed it. The regex tester was a nice bonus I wasn't expecting to actually use.
@nazmiyeb97v This is exactly the reaction I built it for! The "upload-to-server nonsense" was driving me crazy too — glad the JWT decoder finally feels the way it should. And the regex tester being a surprise bonus is the best kind of feedback — that's what having everything in one tab is supposed to feel like 🙏
