About SamToolkit

SamToolkit is a collection of 29 free, browser-based developer and small-business tools — converters, debuggers, generators, and calculators you'd otherwise reach for a dozen different single-purpose sites to do. Pick a tool, use it, close the tab. No account, no sign-up, no upsell.

Most of the tools here run entirely as WebAssembly in your browser: the JWT you paste into the decoder, the JSON you reformat, the palette you extract from an image — none of it is uploaded anywhere. A handful of tools genuinely need a server, because the job itself requires one (checking a live SSL certificate, capturing webhook requests sent to a URL, fetching a page's Open Graph tags) — see the Privacy Policy for exactly which ones and why.

The site is built and maintained by one person, in .NET and Blazor, and is very much a living project — tools get added, fixed, and occasionally retired when they're superseded by a better one. If something's broken or you want to see a tool that doesn't exist yet, see Contact.
