What you get

Everything a managed platform does,on infrastructure you own.

Your database, your data

Threads, runs, and checkpoints live in a Postgres you control. Query them, back them up, keep them in your region.

Plain SQL, plain tables
Your region, your backups
Migrations run on start

Custom auth in Python

Plug in JWT, OAuth, or Firebase with one decorator. Every thread is scoped to its owner.

Agent Protocol API

The endpoints the LangGraph SDK already speaks. Point your client at aegra and keep your code.

POST/threads
POST/threads/{id}/runs/stream
GET/threads/{id}/state
POST/assistants/search
PUT/store/items
POST/runs/crons

Streaming runs

Token, value, and event streams over SSE, with resume after disconnect.

metadata{"run_id": "1ef3…"}
values{"messages": [...]}
messages/partial"Checking the"
messages/partial" order status…"
messages/complete{"content": "…"}
values{"messages": [...]}
end

Workers that survive restarts

A Redis queue with leases, heartbeats, and crash recovery. Scale out by adding instances.

Keep your client code.Point it at your server.

The LangGraph SDK talks to aegra the way it talks to a managed deployment. Change the URL and the client side stays as it is.

VP Engineering & AI, Mercanis

Aegra was exactly what we needed to break free from being locked into LangChain and the rest. We genuinely love what you've built, and we're not just watching from the sidelines, we're contributing.

Here building customer support agents! Already in prod and with awesome results.

Aydar

Founder, tmarket.io

We run Aegra on k8s to serve our entire AI stack. Aegra has been excellent on concurrent load and reliability, we handle our inventory mapping at scale without a sweat.

I have Aegra and a next app running on a 4gb 3cpu VPS and it's been very smooth.

Tomasz Malisz

Senior Software Engineer, Ingenix.AI

I love this project. Aegra has been a great fit for our stack and the developer experience is excellent.

Soufiene Slimi

Aegra really nails that gap. A self-hosted, open source LangGraph Platform alternative with zero vendor lock-in, your own Postgres, and the same LangGraph SDK is exactly what I was hoping someone would build.

Diag n'Grow

We use Aegra for our agents at Diag n'Grow: a data collection chatbot that replaces a fixed questionnaire, and a software audit agent.

It's crazy that there's still no proper solution out there. I was actually about to migrate to Google ADK before finding this.

Open source from day one

The whole server is on GitHub. Read it, run it, fork it. There is no enterprise tier hiding the good parts, and no license key. If you can run Postgres, you can run aegra.
