A growing collection of free, no‑paywall tools crafted for developers and curious minds. Our goal is simple: make the web feel fast again with focused utilities that solve real problems. We’ll keep adding new tools over the years — always online, free to use, and built with performance in mind.
KpsVibe is a self-hosted AI conversation viewer written in C++. It scans local chat logs from tools like VS Code Copilot and Cursor, stores them in SQLite, and serves a clean web interface to browse, search, filter and export your AI conversations. It supports collapsible code and text sections, syntax highlighting, share links, role filtering, and live sync.
PtP-Proxy is a high-performance self-hosted IPTV server written in C++. It supports transparent HLS proxy with per-channel authentication headers, multi-client restreaming via FFmpeg (disk or RAM segments), and a range-aware VOD tunnel for MP4/MKV files. It runs as a single binary with no runtime dependencies, supports TLS, Prometheus metrics, HMAC stream tokens, and can be installed as a Windows service or Linux systemd unit.
Mundo de Bots is a small coding arena where children (and adults) program simple tank bots in JavaScript and watch them battle on a 2D map. The screen is split into the world view, a live bot editor and a help tab that explains step by step how to create a bot without prior programming knowledge. Each bot is just a function that decides how to move, turn and shoot based on what it sees, making it an easy way to learn basic logic, variables and conditions while playing.
KpsLauncher is a task launcher for Windows that allows you to run commands and URLs from a configurable button bar. It is designed to serve as a launcher for multithreaded web crawling. It supports scheduled tasks (cron), task dependencies, multiple instances, log recording, and background error notifications.
DiffPatch lets you paste a unified diff and apply it to an editable file, all through a friendly interface that enhances your productivity when working with AI tools like ChatGPT, Gemini, or Grok. It keeps a per-tab history (commits).
NoJS disables the use of JS on the page you saved, preventing anything else from running. It’s useful for websites that take actions after the page loads, such as certain newspapers that hide content after load.
The best online JSON viewer: generate code, switch between graph and text without losing context, edit safely, pinpoint errors, format, and more.
A Chrome add‑on that speeds up ChatGPT when conversations get very long by pruning older DOM elements so the interface stays smooth.
