Free AI coding agents: verified open-source starting points
Compare public coding-agent projects without assuming that open-source software means zero model or infrastructure cost.
Direct answer
For a free or open coding-agent starting point, first distinguish downloadable open-source software from hosted free tiers. BestAIAgent.in currently has verified upstream identities for OpenHands, Cline, Aider, Gemini CLI, Qwen Code and SWE-agent; individual model or infrastructure costs remain separate.

Verified coding-agent identities
The clean graph verifies repository identity separately from feature, benchmark and pricing claims. That allows the directory to show trustworthy upstream links without pretending every capability has already been independently tested.
- OpenHands
- Cline
- Aider
- Gemini CLI
- Qwen Code
- SWE-agent
Evaluation checklist
- Repository and license provenance.
- Supported execution surface such as CLI, IDE or autonomous software-engineering workflow.
- Required model provider and its separate cost.
- Filesystem, terminal and network permissions.
- Human review before commits, deployments or destructive commands.
Why "free" needs its own definition here
"Free" coding agent tools split into at least two distinct categories worth separating explicitly: open-source software you self-host (the code itself costs nothing, but you still pay for whatever model API it calls), and a hosted product's free tier (usage-limited access to a fully managed service). These carry very different long-term cost trajectories — a self-hosted open-source tool's real cost scales with your own usage of the underlying model, while a free tier's limits are set by the vendor and can change.
License terms matter beyond cost, too: some open-source coding-agent projects use licenses with commercial-use restrictions or copyleft requirements that affect how you can use generated code in a commercial product — check the actual license, not just the fact that the source is publicly visible.
