Open Source
NoSignups is a curated directory of open-source, browser-based tools that share one rule: no account, no signup, no bullshit. It spans design and graphics (Excalidraw, tldraw), developer tools (Hoppscotch, drawDB, JSON Crack), media editors (OpenCut, Squoosh), privacy and security utilities (CyberChef, privacy.sexy), and productivity apps (Grist, CryptPad) — each entry linking straight to a working, self-hostable or hosted alternative to a mainstream SaaS product. It's a good browsing ground for anyone hunting for a free, no-lock-in replacement for a paid tool.
