Open Source LangGraph Platform Alternative (Self Host LangGraph Agents for Free)

I got tired of LangGraph Platform's pricing so I built an open-source alternative.

Why LangGraph Platform is frustrating:

Self-hosted "lite" has no authentication
Enterprise self-hosting costs a fortune
SaaS forces you to use LangSmith
Pricing punishes your success
Complete vendor lock-in

So I built Aegra:

✅ Same LangGraph SDK
✅ Your infrastructure
✅ 5-minute Docker setup
✅ Apache 2.0 license
✅ Zero lock-in

The response has been amazing:

92 GitHub stars in 3 weeks
Real projects migrating over
Developers saying it "saved their life"

One user told me: "You save my life. I am doing A state of art chatbot for mental Health and the Pay for execution node killed my project."

That hit different.

The open source community deserves better alternatives to expensive SaaS platforms.

Would love your feedback!

330+ data teams share what's working (and what's not) - the report

The Metabase Community Data Stack Report 2025 is just out of the oven 🥧

We asked 338 teams how they build and use their data stacks, from tool choices to AI adoption, and built a community resource for data stack decisions in 2025.

Some of the findings:

Postgreswins everything: #1 transactional database AND #1 analytics storage
50% of teams don't use data warehouses or lakes
Most data teams stay small (1-3 people), even at large companies
Trust in AI is shaky: average confidence only 5.5/10

But there's much more to see. Read the full report here or dive deeper into the raw data.

For 2 years my api testing was a mess of go noscripts. so I merged them into (apter), a single binary tool

Hey everyone,

So for like 2 years my workflow for api testing has been these individual go noscripts i wrote for myself. They were super basic, just used static data to hit my local apis. they worked, but it was getting messy.

I got tired of the overhead with big gui tools and didnt want a nodejs runner just for some simple ci tests, so i decided to actually improve my own noscripts. i merged them all together, added a bunch of features I always wanted, and just released it as an open source tool I'm calling apter.

The whole idea is simple: one binary, no dependencies. it covers the whole testing lifecycle. It's all in Go so its super fast.

Features

Run API tests (apter run): This is the main thing you just write your tests in simple json files and its all declarative.
Record Tests (apter record): You run it as a proxy, use your app or curl, and it just writes the test file for you from your traffic.
Verify Traffic (apter verify): you run this while you're coding. It watches your api calls and checks them against your tests as they happen, so you know right away if you broke something.
Instant Mocking (apter replay): just point it at a test file and it becomes a mock server. its good for frontend when the backend isnt ready.

I just put up the first release with binaries for mac, windows, and linux. hoping maybe some of you might find it useful too.

You can check it out on github: https://github.com/Muntader/apter

I'm worried about negative ratings for my software.

Hello! I created an add-on for QGIS, an open-source GIS software. Several users have emailed me thanking me for providing this tool to the community and requesting new implementations. I love it. However, out of the blue, people sometimes give the add-on negative reviews without explanation, without even sending an email complaining about a bug or anything like that. This worries me a lot. Has anyone else experienced this?

I built (yet another) open source MCP Gateway

Hey all,

I built an open source MCP gateway with an admin dashboard. I know there's a few of them floating around already but wanted to create one in Golang for high throughput + lower memory requirements.

Here are the core initial features:

* Security (JWT, OAuth2, Role-base access control, Ratelimiting)
* MCP Server discovery
* Proxies all major MCP protocols - JSON-RPC, websockets, SSE, stdio, streamable HTTP, etc.
* Namespaces for grouping MCP servers
* Built-in plugins: PII filtering, content filtering, etc.
* Logging/metrics
* Custom plugins
* Admin dashboard

Potential roadmap (pending what is in demand or piques my interest!):

* Auto-deployments via helm charts, ??
* Session tracking
* Built-in external integrations within the admin dashboard
* LLM model toggles on/off
* ???

Hey I have a idea for a app for apple or android

App Idea: A Screen Time App That Fights Back (Difficulty-Based Challenges)

Most screen-time apps just nag you or block apps after you’ve hit a limit. That works… if you don’t cheat. But what if using your phone was more like playing a game on “easy, medium, or hard”?

The idea:
• When you install the app, it reads your past screen time and assigns you a difficulty mode.
• Easy if you don’t use your phone much.
• Medium if you’re a heavier user.
• Hard if you’re glued to it.
• Each mode sets how many hours you can use apps per day.
• Every time you open an app, you face a challenge overlay before you can continue:
• Easy → Hold a button for 1 minute.
• Medium → Beat an impossible Tic-Tac-Toe bot.
• Hard → Play a full game of chess.
• If you pass your daily limit, the app still lets you play the challenge — but afterwards it just laughs and says “you’re over your limit 😂.”

Extra features could include:
• MDM profile option (like Opal) to make the app undeletable for stricter users.
• A lighthearted design so it feels like resistance training instead of punishment.

Why it’s different:
• Instead of just blocking, it eats into your time with challenges.
• Heavy users automatically get put on “hard mode,” so it scales with your habits.
• It’s funny, a little brutal, and feels more like a boss fight than a nagging parent.

Would love to see someone make this, especially as an open-source project so it can stay free and grow.

Advice for Beginner Contributors?

Hello everyone,

I am a recent computer science graduate looking to strengthen my project portfolio and begin to make contributions to open source projects. Ideally, I would love to work with something I am passionate about, but I want to find a nice place to start. What advice, if any, would you give to a beginner contributor? I also wish to continue my work on my own personal projects and am interested in creating something that is open source.


Thank you!

A while back, I posted about an all-in-one networking tool I was building. Thanks to your feedback!

Some of you might remember my post about a personal project I was working on to stop the endless juggling between PuTTY, Nmap, subnet calculators, and a dozen other apps. The feedback was awesome and really motivated me to keep pushing.

Based on the initial ideas and what I needed, here's what Ducky can do now:

Multi-Protocol Tabbed Terminal: Open as many tabs as you need for SSH, Telnet, and Serial (COM) connections. No more multiple PuTTY windows!
Real Terminal Experience: The terminal has command history (up/down arrows) and tab completion for common network commands. Backspace and arrow keys finally work just like you'd expect.
Network Discovery & Mapper: A tool that scans your local network and creates a basic visual map of all the devices it finds.
Essential Network Tools:
Ping, Traceroute, Port Scanner
Website Status Checker
IP Lookup (GeoIP/ASN info)
DNS Lookup (A, AAAA, MX, NS, TXT records)
Hostname <-> IP Converters
Essential Security Tools:
Vulnerability Scanner: Look up any software (like "Apache 2.4.51") to find its known CVEs from the NIST database.
Password Strength Analyzer: Instantly check how strong a password is.
Hash Calculator & Cracker: Calculate MD5/SHA hashes and run a basic dictionary attack.
And More: A dockable notepad, customizable themes, saved session manager, etc.

This is where I need your help!

The project is fully open-source on GitHub, and I'm looking to build what the community actually needs.

Got a Feature Idea or an Enhancement?
Found a Bug or something that feels clunky?

Please, head over to the **GitHub Issues page** and let me know! No idea is too small, and every bug report helps make the tool better for everyone.

Link to the full project on GitHub: https://github.com/thecmdguy/Ducky

Finally, I'm developing this in my free time. If you find Ducky useful and want to support its future development, you can buy me a coffee. It's never expected, but always deeply appreciated!

How do you prioritize contributions from community vs. strategic roadmap needs?

Open source projects often juggle community requests and long-term direction. What frameworks or rules help you avoid getting pulled in too many directions?

Text to Speech Free Open-Source Code

Hi,
I tried searching GitHub for a text-to-speech project, but I couldn’t find anything suitable.
Do you have any tips? Maybe you know of some open-source code that could help me.
I also checked a few APIs, but most of them aren’t very affordable.

For anyone interested in a Window Switcher in the form of a Pie Menu

I love the pie menus in Blender and I got fed up with switching to the wrong window when hitting Alt+Tab, so I made something to replace it in the form of a pie menu: MightyPie Revamped. It has the benefit of not needing the taskbar as well (except for the Tray).

I also built in a lot more functionality like media control, maximizing/minimizing windows under the cursor and more.

This is now the second iteration of my program: https://github.com/Rayzorblade23/MightyPie-Revamped
