Sapir Software

Small tools, done right, with nothing to hide.

Browser extensions that do one job properly. Everything runs on your own machine — no uploads, no analytics, no tracking, no accounts. The only network request any of these tools makes is a single license check, and only if you choose to buy the paid version.

Full Page Screenshot

Capture an entire webpage in one click — PNG, JPEG, or PDF.

Actually captures the whole page — lazy-loaded images resolved, sticky headers shown once instead of repeating
Pro: real paginated A4 PDFs with smart page breaks and clickable links, not one giant image strip
Only ever sees the tab you're capturing — no access to the other sites you visit

Modify HTTP Headers — HeaderForge

Set, remove, and override HTTP headers for testing and debugging.

Works on XHR, fetch, and POST requests — not just page loads
Shows you when a rule actually fires, so you're never guessing whether it worked
Unlimited rules free. Pro adds response headers and named profiles for switching environments
