Build apps that think, act, and coordinate across your stack.
ArchAstro is the server side for AI-native applications: a workflow engine, an agent framework, and an integration layer exposed through Swift and TypeScript SDKs.

The A-ha moment
Zapier + ChatGPT + APIThe infrastructure you always wished existed.
Trigger a workflow, invoke an agent, enrich with data, and ship a response — all without stitching together ten vendors.
Three pillars
Everything your AI product needs to move with confidence.
Build for workflows, not single calls. ArchAstro keeps agents, data, and integrations in one composable platform.
Workflow Engine
Design multi-step automations that move from trigger to action without brittle glue code.
AI Agent Framework
Spin up task-focused agents with tools, memory, and guardrails built for real work.
Integration Layer
Securely connect external systems so agents answer with real context, not guesses.
Core concepts
The building blocks behind every AI-native app.
Workflows orchestrate multi-step logic, agents handle intelligence, integrations supply context, and client-side agents keep experiences fast and private.
Workflows
Orchestrate AI + human steps, from enrichment to follow-ups, in a single pipeline.
AI Agents
Purpose-built agents with clear goals, tools, and conversation state.
Integrations & Context
RAG-ready data connectors that keep answers grounded in your source of truth.
Client-Side Agents
Run the loop locally for privacy, speed, and deeper in-app control.
Message trajectory
See the full chain of tool calls and responses.
AI-native mindset
Quirks that make your product resilient.
Embrace asynchronicity
Use WebSockets and stream responses so the UI feels alive while agents work.
Prompt with intent
Treat the system prompt like a constitution. Be specific, persona-driven, and iterative.
Machines calling machines
Tool design matters. Name functions clearly and build safeguards for actions.
Understand trajectory
Debug the full chain of tool calls and responses, not just the final message.
Plan for rate limits
Backoff and batch to keep the experience stable and costs predictable.
Dynamic tools
Let integrations unlock tools automatically and handle missing access gracefully.
SDKs
Multi-language SDKs that feel like first-class frameworks.
TypeScript and Swift SDKs give you the same surface area as the platform — threads, messages, workflows, integrations, and tool calls — with real-time updates baked in.

Go from first agent to full-stack automation.
Explore the reference apps, run evals, and ship with confidence using the same tools we use internally.
