Open-source personal AI assistant that runs locally on your own devices and connects to WhatsApp, Telegram, and Discord. Features persistent memory, proactive notifications, and community-built skill extensions. Formerly known as ClawdBot. Free and open source.
Free, open-source download manager written in Python, managed entirely through a web interface. Lightweight enough to run on a home server, NAS or router, with plugins to automate repetitive downloads.
Why I recommend it: Worth it only if you already run a home server and download large files regularly. Same rule as any download tool: what you download is your responsibility, and file hosts are a common route for malware.
Free, open-source command-line tool for downloading video and audio from thousands of sites. Actively maintained on GitHub, runs on Windows, macOS and Linux, and is the tool most other download apps wrap.
Why I recommend it: useful for saving your own recorded talks, webinars and openly licensed lectures so you can watch or transcribe them offline. Downloading material you have no right to is a different matter and often breaks the site's terms or the law where you live, so keep it to your own content and openly licensed work.
The Python framework behind Stanford's HELM leaderboards, released under the Apache License 2.0 (licence file read, not copied from a roundup). You install it with pip, describe a run (scenario plus model plus metrics), and it evaluates the model and produces the same structured results the public site displays, including its own local web UI for viewing them. It supports hosted model APIs and locally run open-weight models, and you can add your own scenario to test a model on your own task or data. Free to use, modify and use commercially under Apache 2.0; you pay only for whatever model API calls or compute your own runs consume.
Why I recommend it: Worth it if you need to prove a model is good enough for a specific job rather than good in general — write your own scenario with your own examples and run it. Two practical warnings: the published leaderboard runs are large and expensive to reproduce in full, so start with a single scenario and a small instance count, and if you evaluate a paid API model the token costs are yours, not Stanford's.
Open source framework for building AI agents, free to clone and run yourself.
From the site: Open source agentic operating system. Contribute to elizaOS/eliza development by creating an account on GitHub.
