We release the open source projects and free tools we build at Codefein to everyone on GitHub. In this article we introduce three of our projects and clarify the difference between open source licensing and free software.
Build it yourself or hire an expert? We explain the technology transparently — but every project also has time, risk and hidden-cost dimensions.
1. Instant Game Translator (Free)
A local AI program that reads subtitles in PC games in real time (OCR) and overlays translated subtitles on the game. It never touches game files or memory; it only reads screenshots, so it never conflicts with anti-cheat systems. Includes OCR in 100+ languages, Google/DeepL/ChatGPT/Gemini translation engines, game profiles and cache support. It is free, though its license is closed (all rights reserved).

2. MultiPack (Free)
A multi-AI-agent platform that writes code with 4 different models in a Planner → Coder → Reviewer → Regulator chain. Offers live token streaming (SSE), self-healing watchdog, checkpoints and a kanban task board, a Turkish voice assistant and local Ollama/LM Studio support. Model cost is zero. Its source is open on GitHub and it is free.
3. LI Monitoring (Open Source — GPL-3.0)
A GTK-based battery health analyzer and optimization tool for Linux laptops. Includes wear level, temperature/voltage/current telemetry, live charge graphs, one-click Lenovo conservation mode and a calibration guide. Licensed as open source (GPL-3.0); anyone can inspect, modify and contribute. Flatpak builds are compiled and released automatically via GitHub Actions.
Open Source vs Free
Open source is a license type: it permits inspecting, modifying and distributing code (e.g. GPL, MIT). Free only says the cost is zero; the code may be proprietary. In our case LI Monitoring is open source; the other two tools are free.
If you like these open source projects, leave a star, contribute, or adapt them to your needs. If you want us to build a similar tool for your business, contact us.
