Developer Tools
HappyRobot is a fully programmable platform. Everything you can do in the UI, your engineering team can do through code.
Everything you can do in the platform, you can do through code
REST API
Build, trigger, and manage every part of HappyRobot programmatically such as workflows, agents, integrations, contacts, usage, and more across 20+ resource areas. Fully documented so your team can explore and test the full API without writing a single line of code.
TypeScript SDK
Embed HappyRobot directly into your own applications with Node.js or TypeScript backend - calls, transcripts, phone number management, and more, all accessible from your existing backend without building custom infrastructure around it. Failures are handled automatically so your team never has to manage error handling.
MCP Server
Expose the platform as tools in any MCP-compatible environment to create workflows, manage integrations, run evals, and configure agents through natural language without leaving your existing dev tooling.
Deploy voice or chat agents into your
web surface
Browser-based voice over Web RealTime Communication (Web RTC) - users click a button and speak directly to an agent from any web page, no phone number or telephony infrastructure required. Pass any context into the agent at call start, receive real-time web hook events as the conversation progresses, and simulate degraded audio conditions to stress-test agents before production.
Built on top of the web SDK, deploy a fully featured text agent on any web property with a single script tag. Supports file uploads of any type - documents, images, audio, and video, so agents can read, transcribe, and act on whatever users send. Session continuity across page navigations means conversations never reset mid-browse, and authenticated context injection at session start means users who are already logged in never have to identify themselves again.
Build and extend without limits
Workflows as code
Define your entire agent workflow including prompts, nodes, tools, and logic as versioned code. Engineering teams can build in their own environment, review changes in pull requests, and promote to production through the same source control process they use for everything else.
MCP for Context
Read and write directly to the Context data layer through MCP. Query the same tables your agents write to during live execution, push data in from external systems, and build workflows that treat Context as a first-class data source, all through natural language in your existing dev tooling.
Context REST API
Context, the platform's data layer exposes a public REST API and managed REST gateway, making it a two-way integration point with your data lake, analytics platform, BI tools, and downstream operational systems. Query or write to the same layer your agents use during live execution.
Code blocks
Drop custom code anywhere in a workflow when precision matters to parse API responses, transform data structures, apply business rules, or compute values with full programmatic control, without leaving the workflow editor.
200+ integrations
Pre-built integrations for Salesforce, MongoDB, Redis, Google Maps, and 200+ other platforms handle authentication, API contracts, and response parsing so your team can wire HappyRobot into your existing stack without building or maintaining custom integration code.
