Stop Paying $20/Month for a Locked-Down Coding Agent
Zosma Code is a free, open-source coding harness built on the leanest agentic SDK ever created. Use any LLM — local or cloud. Deploy anywhere. Extend everything. Your workflow, your rules, your data.
Zosma Code vs. Overpriced Coding Assistants
Every feature of a $20/month coding agent, plus total freedom. No lock-in. No data leaks. No forced upgrades.
What You Get With Zosma Code
Everything you expect from a coding AI — plus the freedom that proprietary tools will never give you.
Any LLM, Anywhere
OpenAI, Anthropic, Google, DeepSeek, Llama, Mistral, Qwen — or your own fine-tuned model. Run locally, in your cloud, or on-prem. Switch with a config change. We never lock you in.
Free. Not Freemium.
No $20/month Pro plans. No $200/seat Enterprise tiers. Zosma Code is fully open source. You pay for LLM tokens only — or run local models at zero marginal cost.
Fully Local & On-Premise
Run everything on your hardware behind your firewall. No data leaves your premises. Complete data sovereignty with zero external dependencies.
Your Workflow, Not Theirs
Other AI coding tools force you into their workflow. Zosma Code is a harness — it adapts to your existing processes. Configure, extend, and shape it however you need.
Built on the Minimalist SDK
Zosma Code is built on pi_agent_rust — the leanest, most powerful agentic SDK in existence. No bloat. No unnecessary abstractions. Just raw capability you can extend in any direction.
Extensible by Design
Plugin architecture. Custom tools. MCP support. Full SDK access. If you can imagine it, you can build it on Zosma Code. We don't limit what you can do.
Runs Anywhere
Docker, Kubernetes, bare metal, air-gapped environments. Your laptop, your data center, or the cloud. Zosma Code is portable by design.
Agents That Coordinate & Verify
Multiple AI agents work together — one codes, another reviews, a third runs tests, and a fourth verifies the output. They coordinate, validate, and deliver without human hand-holding.
Enterprise-Grade Security
No dependency on external APIs when running locally. Full audit trails. Role-based access control. Encrypted communication. Your code never leaves your infrastructure.
Stop Renting Your Coding Agent
Own your AI development infrastructure. Deploy Zosma Code on your terms — with your LLM, your data, and your workflows.
