About OmniDev
Free, fast developer tools that run entirely in your browser.
What is OmniDev?
OmniDev is a collection of free, open-use developer utilities designed to help engineers, designers, and curious people work faster. Every tool runs entirely in your browser — no account, no sign-up, no data sent to a server.
We built OmniDev because we got tired of copy-pasting between fragmented tools. One place, zero friction, instant results.

Who We Are
OmniDev is built and maintained by PSWK DEV, a small team of software developers who enjoy building tools that make everyday development tasks easier. We believe great tooling should be accessible to everyone — free of charge and free of sign-up walls.
// Mission
