Developers seem to trust tools significantly more when they know nothing leaves the browser.

Moving parsing/processing logic to the frontend created a few unexpected challenges:

handling large JSON files without freezing the UI
crypto operations in-browser
regex performance issues
keeping bundle size reasonable
avoiding memory spikes with diff tools

One interesting UX pattern:
users care less about how many tools exist and more about whether they trust the environment enough to paste sensitive data into it.

Curious if others here have noticed the same trend with local-first web apps?

Hey I've been building DevBench and wanted to share it here. It's a collection of 100+ developer tools that run entirely in your browser — JSON formatter, Base64, JWT debugger, Regex tester, UUID/ULID/NanoID generator, diff checker, YAML validator, AES encryptor, cron parser, and a lot more. The main thing I care about: nothing you paste is ever sent to a server. No account required, no rate limits. https://www.devbench.co.in Would love any feedback — missing tools, UI issues, anything. Also open to suggestions for what to add next.

I’ve been experimenting with fully client-side developer utilities lately, and one thing surprised me

I built DevBench — 100+ free browser-based dev tools, no signup, nothing uploaded to a server
