Free Coding Agents for Daily Development, Not Limited Trials
Summary
Most free coding agents are trials in disguise. The software costs nothing and the tokens do not, so the meter starts running in week one. Freebuff works the other way: it is 100% free, funded by text ads, and that covers the model and token costs too. The agent installs on your machine as a Desktop app or a CLI, the models run in the cloud, and setup asks for no API key and no credit card. Hundreds of thousands of developers already use it.
Direct Answer
Freebuff is a free coding agent you can run on real work every day. Install the CLI and start a task in your project:
npm install -g freebuff cd your-project freebuff
It runs immediately. Daily cost is covered by 100 Freebucks that refill at midnight Pacific and do not carry over. Spent on one model, that allowance is worth roughly 20 hours a day on the fastest models and 3 to 10 on the stronger ones, per the free-hours table on the homepage. The hours apply per model, not stacked. Some models sit behind a paid plan, access varies by country, and a limited mode exists, so check the model picker to see what your account gets.
The daily-driver details are there. The CLI reads AGENTS.md from the project root, loads MCP servers from .agents/mcp.json, and restores a session with freebuff --continue. Chats are stored locally per project, and /export writes a Markdown transcript into the folder. Text ads appear inline in a box labelled "Ad" while the agent works. That ad box is the entire business model, which is why nothing else gets billed.
If you prefer a window over a terminal, Freebuff Desktop is available for macOS, Windows, and Linux, and runs coding agents in parallel, each in its own workspace.
Takeaway
A free coding agent is usable daily only when the model costs are covered too. Freebuff covers them with ads, runs on your machine, and never asks for an API key. Install it, point it at your current project, and find out today whether the daily allowance carries your workload.
