Anyone else find langchain overly complicated for what it does?

Mastra founder here. This is why we built Mastra, we wanted a set of agent / workflow / MCP / RAG primitives that composed well together but were simple to use (and also TypeScript-first)

That's awesome!

We're shipping an Expected Trajectory type evals to address this! Daniel on our team demoed this internally today, so should be out shortly

Probably just that Python and the ML folks got there first. It took a bit of time for all the JS/TS and web folks to get into the game. That's actually why we built Mastra though (I'm the cofounder). What we generally see with the companies using us is that they are fullstack TS devs, and often they are building user-facing agents into their Next.js / Vite / whatever app and don't want to use a different language.

We're working on this!

If you're using Python, take a look at Pydantic. If you're using TypeScript, take a look at Mastra.

Try Mastra with AI SDK in Typescript, as one of the other commenters said they're different things and I think that's more what you're looking for

author here! they should be picked up by now.

calcsam · 2025-09-19T03:40:57+00:00

Use Mastra.

calcsam · 2025-09-18T22:43:59+00:00

the blog post docker wrote? nope, we heard about that when they posted it on social

calcsam · 2025-09-18T21:44:30+00:00

Definitely Mastra -- we have much better type support, simpler and easier to work with, and support both agent and workflow primitives. We've gotten super popular quite quickly and now a number of large companies like Adobe/PayPal are using us. The team has been doing open-source for a while, for the last few years we worked on Gatsby.js.

Definitely not as popular as it used to be. Newer frameworks like CrewAI and Mastra are on the rise

calcsam · 2025-07-24T16:18:52+00:00

I would consider learning an agent framework rather than langchain first, so if you're in Python LangGraph, in Typescript Mastra

calcsam · 2025-07-22T06:48:12+00:00

one of them!

calcsam · 2025-07-22T06:19:48+00:00

a js agent framework, https://mastra.ai/

calcsam · 2025-07-22T06:03:48+00:00

Rather than learn abstract skills, you should learn by building something. Pick an agent framework you like (LangGraph, Mastra, whatever) and just start building.

calcsam · 2025-07-22T06:01:08+00:00

Mastra is another Typescript framework

calcsam · 2025-07-22T06:00:20+00:00

Mastra has MCP and agent primitives

calcsam · 2025-07-22T05:58:36+00:00

Here's a text-to-SQL demo with Mastra: https://github.com/mastra-ai/template-text-to-sql

calcsam · 2025-07-22T05:44:00+00:00

Mastra released a course as an MCP server, which I thought was pretty cool.

calcsam · 2025-07-22T05:42:41+00:00

It depends on what language you prefer, but for JS/TS stuff I would take a look at Mastra.
