Spec-driven AI factory. Use with any agentic CLI. Language-agnostic. Safe by design.
Like GasTown, but agents can't cheat, leak, wreak havoc.
Full feature preview at:
⚠️ Status: Alpha. SaifCTL is under active development. See the Roadmap for what's coming next.
SaifCTL implements state-of-the-art (early 2026) architecture for Agentic engineering.
SaifCTL guarantee:
- The AI builds exactly what you asked for.
- The agent is locked in a loop and physically cannot stop until your new TDD tests pass.
- The AI can't break previously-built features.
- All features built with SaifCTL are protected by tests. AI can't break or change them. Regressions are mechanically impossible.
- The AI breaks nothing on your machine.
- The agent runs in a zero-trust, sandboxed Docker environment. Your existing codebase is safe.

The AI agent is trapped in a rigorous convergence loop. Every time it writes code, it must survive three stages before opening a PR:
- The Gate: Your linters, type-checkers, and other static analysis tools.
- The Reviewer: Adversarial AI that scrutinizes the diff to ensure it matches the spec without taking shortcuts.
- Holdout Tests: Hidden tests. Agent can't see them. Can't fake a pass.
You only get notified when the code emerges victorious.
SaifCTL supports out of the box:
- All major LLM providers + OpenRouter + OpenAI-compatible APIs
- 14 Agentic CLI tools
- 4 Programming languages (Node.js, Python, Go, Rust)
- All major Git providers
SaifCTL runs as a CLI that spins up coding agents in ephemeral Docker containers on your machine. Self-hosted and Kubernetes (Helm) deployment support is underway.
SaifCTL is currently in active development. The Docker isolation environment and VSCode extension are dropping in a few weeks.
Star the repository to get notified of the Alpha drop, or Join the Design Partner Waitlist to get early access.
See the Step-by-step usage for a detailed walkthrough of the workflow.
For shorter, task-focused tutorials, see Guides.
The SaifCTL VSCode extension provides a dedicated sidebar panel to manage your entire AI engineering workflow directly from your editor.
What the extension does:
- Manage Features: Visual tree view of your features. Create new features, or manage existing ones through GUI.
- Design & Run: One-click actions to generate specs (
saifctl feat design) and start the coding swarm (saifctl feat run). - Track Runs: A Kubernetes-style dashboard of all your agent runs. See status (success/failed), view run configs, and instantly resume failed runs or clear old ones.
- Node.js 22+
- Python 3.12+
- Docker
- Git
- LLM API key
- Linux or MacOS (Windows is not supported yet)
Every component of SaifCTL is fully modular. You can swap, customize, or disable to fit your team's needs:
- Want to use a different LLMs for coding and designing agents? Easy.
- Want to use your custom Playwright setup for testing? Done.
- Need to enforce strict filesystem rules? It's built in.
