The platform for AI agents with apps
Build intelligent solutions with the power of agents interacting with your custom apps. Arca provides the platform, so you can focus on your business.

What you get with Arca
Agent shell for time to market
Arca gives your LangGraph agents a complete product shell: UI, API, auth, observability, and evals without writing platform code. You register your agent as a plugin and ship.
Arca platform capabilities
Engineered to support your business
Chat UI
A production-grade chat interface for your users, out of the box. White-label, ready to deploy under your brand.
Agent app
Extend the workspace with your own React components. Define controls, visualizations, or any interaction your agent needs, rendered alongside the chat as part of your plugin.
REST + WebSocket API
Register your agent once and it's callable via standard REST and WebSocket endpoints. Ready to integrate with existing systems or expose to users.
Auth & session management
JWT authentication, RBAC, and refresh token handling come with the platform. Multi-user, multi-agent, session isolation.
Chat history
Conversation persistence per user, per agent. Users pick up where they left off.
Observability
Agent runs are tracked, inspectable, and comparable. See what happened, when, and why.
User memory (on the roadmap)
Arca maintains memory across sessions and passes it to your plugin. Your agent knows who it's talking to.
Usage metering (on the roadmap)
Define limits per user, Arca enforces them. Track who uses what and how much.
Evals
Define quality benchmarks and run them locally or in CI. Business outcomes, technical performance, accuracy, and risk are measurable on each release.
