Top 23 Microservice Open-Source Projects

1. traefik

   1 207 64,758 9.7 Go

   The Cloud Native Application Proxy

   

   Project mention: EKS vs k3s on AWS for startups: cost, complexity, and when to choose each | dev.to | 2026-04-26

   k3s: You run the control plane on an EC2 instance. It starts in under a minute, ships with Traefik and a working storage class, and upgrades when you decide. Nothing AWS-specific unless you want it.

2. AppSignal

   AppSignal knows why the f*#k it crashed. Stop vibe-debugging. Every exception, every backtrace, grouped so you see patterns, not noise.

   

3. Previous Serverless Version 0.5.x

   2 90 46,918 9.7 JavaScript

   ⚡ Serverless Framework – Effortlessly build apps that auto-scale, incur zero costs when idle, and require minimal maintenance using AWS Lambda and other managed cloud services.

   

4. Kong

   3 23 44,082 7.1 Lua

   🦍 The API and AI Gateway

   

   Project mention: AI Gateways in 2026: a field guide to the 106 cost problem | dev.to | 2026-06-13

   Self-hosted, your infrastructure. Your keys, your network, no per-token middleman fee — you pay only for the box it runs on. LiteLLM is the broad default (Python, 100+ providers, virtual keys and budgets). If the gateway must never be your bottleneck, Bifrost (Go) and TensorZero (Rust) are built for throughput. If you already run Kubernetes, the AI plugins on Kong, Higress or Apache APISIX mean one less new service to operate.

5. istio

   4 112 38,371 9.8 Go

   Connect, secure, control, and observe services.

   

   Project mention: 6 Agent Gateway Platforms That Actually Exist in 2026 (And What They're Good For) | dev.to | 2026-05-04

   Quick mental model: an agent gateway is the load-bearing wall between your agents and the rest of your infra. LLM routing, MCP tool governance, agent registry, A2A traffic, audit logs. Same energy as Istio or Kong, just pointed at agents instead of microservices.

6. Nacos

    Project mention: Ask HN: What are you working on? (June 2026) | news.ycombinator.com | 2026-06-14

    2. I finished adding image uploads. Now you can add and view image attachments.

       This was quite a challenging task because there are a lot of security implications, and Cloudflare Workers don't support sharp. So I was implementing all the pixel bomb detection, optimizations, and other stuff by myself. Also, [imgproxy](https://imgproxy.net) came in handy as a price-efficient image processing solution.
