HKUDS/CLI-AnythingGitHub repositoryTurns an ordinary program like GIMP, Blender or LibreOffice into a set of commands an AI agent can use on its own, without screenshots or clicks.

shader-effects-inc/shadersGitHub repositoryShimmering gradients, glass, metal and cursor trails for your site, snapped together from ready-made pieces like a construction kit.

reconurge/flowsintGitHub repositoryAn open-source platform for graph-based OSINT investigations: a domain, email, username, phone number or crypto wallet grows into a map of connections. It runs on your own machine in Docker, so the data never leaves it.9.9kcommit this monthchecked October 7, 2026
FreebuffServiceImagine a coding agent in your terminal with no subscription, no API key and no card. Freebuff pays for the models with ads shown between agent turns. The catch is in the small print: outside 24 countries you get a limited mode, and your prompts help pick the ads.freemiumchecked October 5, 2026
tester-army/e2eGitHub repositoryA test step is a sentence like "upgrade the workspace to the Pro plan", and an agent finds the buttons itself on a website, an iPhone or an Android app. Successful actions are recorded and replayed later without calling the model. Open source, Apache-2.0.11kcommit this monthchecked October 5, 2026
