FlowToolkit
30+ FREE Tools 100% in your browser. No Account needed
A premium collection of free, browser-based developer and productivity tools — CSV splitter, JSON formatter, unit converters, BMI, sitemap & robots generators, image resize, and more.
Hey Product Hunt! 👋
I'm Mubashar, the solo builder behind FlowToolkit.
This started from a frustration I kept running into — every time I needed to split a large CSV or format a JSON file, I'd land on some sketchy site that uploaded my file to a server I knew nothing about. For personal files that's annoying. For client data, it's a real problem.
So I built FlowToolkit around one rule: your data never leaves your browser. Ever.
Every one of the 32 tools — CSV splitter, JSON formatter, PDF editor, image resizer, background remover — runs entirely client-side using the browser's own compute. No uploads. No accounts. No server seeing your files.
It sounds like a small thing, but once you feel the difference — a 500MB CSV split in under 2 seconds, locally — it's hard to go back.
Would love to hear what tools you'd want added next. I'm shipping new ones regularly based on feedback. 🚀
