Stratus SDK

The Azure-first agent SDK for TypeScript

Stratus SDK launched on April 15, 2026 with 3 votes, #2,709 of 21,248 launches that month and more than 50% of that year's launches.

What it does

Every TypeScript agent SDK I tried treated Azure OpenAI as a second-class citizen. Stratus flips that. It's built Azure-first and includes everything you'd expect: tools, subagents, handoffs, sessions, streaming, structured output with Zod, guardrails, hooks, tracing, and MCP client support. Plus Code Mode, which lets the model write code to orchestrate tools in a loop instead of one call per turn. If you're on Azure and tired of adapter tax, this is for you.

TypeScript agent SDK purpose-built for Azure OpenAI

Stratus is a TypeScript agent SDK purpose-built for Azure OpenAI. One run() call handles the entire tool loop. The types are strict. The API is small. Azure's v1 API lets you use the standard OpenAI() client, point it at your endpoint, and things mostly work. But "mostly" breaks down fast in production. The OpenAI SDK gives you chat.completions.create() . Everything else is on you: import { createModel, createSession, tool } from "@usestratus/sdk" ; import { z } from "zod" ; const model = createModel (); // reads AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY, AZURE_OPENAI_DEPLOYMENT const getWeather = tool ({ name: "get_weather" , description: "Get current weather for a city" , parameters: z.…from usestratus.dev

    Hi HN! I’m Tony, co-founder of Inngest. I wanted to share AgentKit, our Typescript multi-agent library we’ve been cooking and testing with some early users in prod for months. Although OpenAI’s Agents SDK has been launched since, we think an Agent framework should offer more deterministic and flexible routing, work with multiple model providers, embrace MCP (for rich tooling), and support the unstoppable and growing community of TypeScript AI developers by enabling a smooth transition to production use cases. This is why we are building AgentKit, and we’re really excited about it for a few…

    Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

  • With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
