SnapMark
Screenshot & annotate. All local. Free or $39 once.
SnapMark is a privacy-first screenshot and annotation tool for Chrome. Everything happens locally — nothing is ever uploaded. 5 capture modes: Visible, Full Page, Region Select, Element Picker, Timed Capture. 8 annotation tools: Arrow, Rect, Ellipse, Text, Freehand, Blur, Step Numbers, Crop. Free: all modes, all tools, PNG + clipboard, no watermark. Pro $39 lifetime: JPEG/WebP/PDF, Timed Capture, 100 history, 100 undo. No subscription. Built with vanilla JS. ~50KB. 100% local. No sign-up.
I was a paying FireShot user for years, but they started putting watermarks even on paid plans — and recently killed
their lifetime option to go subscription-only. Awesome Screenshot forces cloud uploads. Lightshot deletes your screenshots. There wasn't a tool that combined privacy + no watermark + one-time payment, so I built one.
Tech: vanilla JS + Canvas 2D, ~50KB. Full-page stitching uses 50px overlap + gradient fusion to eliminate seams from sticky headers. License server is Cloudflare Workers + D1. Everything else is local.
Free is genuinely functional — all 5 capture modes, all 8 annotation tools, no upsell walls. Pro is $39 once.
Happy to answer questions about the build, CWS submission, or full-page stitching. Thanks for checking it out
