OpenToolsKitã«ã¤ã„ã¦
OpenToolsKit is an open-source browser tool platform that launches with 95+ PDF tools, a workflow editor, and public source distribution.

We believe private browser tools should stay accessible, inspectable, and useful beyond a single file format. That is why OpenToolsKit has been shaped into a broader browser-tool platform.
Unlike traditional services that depend on remote processing for routine document work, OpenToolsKit keeps core flows in the browser where applicable and keeps source availability visible through a public AGPL repository.
The current public site focuses on PDF tools, workflow editing, and source-visible browser utilities while preparing the platform for additional tool families.

This stack supports browser tools, static export, local processing, and public-source trust surfaces without forcing a server-bound editing model.
Clearly derived, clearly different
OpenToolsKit is based on PDFCraft under AGPL-3.0, then reworked into a broader browser-tool platform with a new shell, theme system, sponsor model, workflow/editor focus, and Cloudflare deployment path.
Public source stays visible
The live service points to a public GitHub repository so users can inspect code, report bugs, and verify the AGPL source corresponding to the production deployment.
Clear project boundaries
The site separates browser-side file processing, public source obligations, support paths, and optional funding surfaces so users can understand what each part of the project does.
