Browser-based agentic interface from Engine Labs. Multi-model with Alloys orchestration system routing to GPT-5.2, Claude Opus 4.5, Claude Sonnet 4.5, Gemini 3 Flash based on task requirements. Free tier offers zero-cost entry point for async development workflows. Target: developers wanting agentic delegation without subscription costs.
Note: Engine Labs (cto.new) and All Hands AI (OpenHands) are separate companies. While cto.new references OpenHands conceptually, they have distinct funding, leadership, and product strategies.
cto.new occupies a unique position—multi-model orchestration and async task delegation at no base cost. Best for developers comfortable with browser-based workflows who want to experiment with frontier models. The Alloys system is a genuine differentiator reducing vendor lock-in concerns.
Adoption & Proof Points
- 30,000+ developers signed up in first week
- 26,893 GitHub App installs
- Enterprise developers at Adobe, Docker, Twilio, PwC actively using
- 300+ billion frontier model tokens consumed
- 10,000+ codebases receiving shipped code
- Northflank infrastructure partnership for microVM scaling
Recommended Use Cases
- Developers wanting async task delegation without subscription costs
- Teams experimenting with different models for coding tasks
- Individual developers handling personal projects
- Cost-conscious teams wanting agentic features
- Proof-of-concept and experimentation where SSO not required
Risks & Limitations
- SSO/SAML absent: Deployment blocker for enterprises with IdP requirements
- No enterprise tier: No SLAs, dedicated support, or contractual commitments
- Funding runway: $5.7M seed supporting compute-absorbing free model—sustainability unproven
- Newer product: Less mature than established competitors
- BYOK dependency: User responsible for provider security posture
Capabilities & Integration
Agentic depth: Dedicated planning and coding agents operating in sandboxed Northflank microVMs. Async task delegation with background execution. Multi-turn conversations with edit/rollback controls. Task Runner executes builds automatically. Live Preview (GA Dec 2025) provides real-time frontend feedback.
Context handling: Git repository understanding, file system navigation. Supports .ctorules for project-level context. MCP overhaul (Dec 2025) added global configuration, per-chat selection, improved HTTP/SSE/stdio handling. Can browse web for documentation when permitted.
Integration surface: Browser-based interface with GitHub App (26K+ installs). Deep workflow integrations with Linear, Jira, GitHub, GitLab, Slack. @cto mention and label-based activation for async team workflows.
Extensibility: Model-agnostic via Alloys—routes to optimal model per subtask. Custom system prompts via .ctorules. cto.new/bench provides 72-hour rolling success rate transparency.
