24 alternatives to I built a fuse box for microservices

Hey HN! I'm Rodrigo, I run distributed systems across a few countries. I built Openfuse because of something that kept bugging me about how we all do circuit breakers. If you're running 20 instances of a service and Stripe starts returning 500s, each instance discovers that independently. Instance 1 trips its breaker after 5 failures. Instance 14 just got recycled and hasn't seen any yet. Instance 7 is in half-open, probing a service you already know is dead. For some window of time, part of your fleet is protecting itself and part of it is still hammering a dead dependency and timing out,…

Openfuse is a centralized control plane for managing circuit breakers across distributed microservices. It solves the problem where individual service instances detect failures independently, causing some to trip their… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Excited to share the project I've been working on for the past 7 months! We've seen nearly weekly attacks against the open source software supply chain. I saw the seeds of this trend start in the mid 2015s as an open source maintainer and I've watched it only get worse over the years. I finally decided to try to solve this problem. Socket is taking an entirely new approach to one of the hardest problems in security in a stagnant part of the industry that has historically been obsessed with just reporting on known vulnerabilities. Unlike other scanning tools, Socket actually analyzes the…

    Hey Hackers. This is a project I solo-developed that turns completed PCB assemblies into an easy to use boardview with some accompanying boardscans. There are lots of easier and better ways of doing this, but this is an experimentation to do it as cheaply as possible, with the highest quality and lowest chance of errors. The technical details are in the link. Most public boardviews are almost entirely the result of industrial espionage, other than a few encrypted subscription based software platforms that provide extensive access. The process output is released as donationware, as my main…

    Telebugs▲391

    Hey hackers! In January 2025, I started building Telebugs. It's an installable error tracker that works with Sentry SDKs. I come from a Rails background and previously worked at an error tracking/APM company, so I figured: why not build my own? I wanted a simple, reliable tool I could own outright, without surprise bills for overages. Telebugs is built with Rails 8, Hotwire, TailwindCSS, and SQLite. Like 37signals’ ONCE products (my inspiration), it’s pay-once: prep your hardware, run one command, and you’ll be up and running in 10 minutes (5 minutes refers to the actual installation…

    Hey HN, I am building an open source platform to make on-call better and less stressful for engineers. We are building a tool that can silence alerts and help with debugging and root cause analysis. We also want to automate tedious parts of being on-call (running runbooks manually, answering questions on Slack, dealing with Pagerduty). Here is a quick video of how it works: https://youtu.be/m_K9Dq1kZDw I hated being on-call for a couple of reasons: * Alert volume: The number of alerts kept increasing over time. It was hard to maintain existing alerts. This would lead to a lot…

    I love getting cool swag from hackathons and I also love designing PCB's, so when my friend asked me if I would design hackathon badges for a large game jam in singapore, I was absolutely down! The theme of overglade was a "The game jam within a game", pretty cool concept right! High schoolers from around the world were flown out to the event by hackclub after they spent about 70 hours designing their own game. These badges needed to be really cheap and simple, because we were going to manufacture about a hundred in a pretty limited amount of time. I went with a zero-power approach, which…

Langfuse is OSS observability and analytics for LLM applications (repo: https://github.com/langfuse/langfuse, 2 min demo: https://langfuse.com/video, try it yourself: https://langfuse.com/demo) Langfuse makes capturing and viewing LLM calls (execution traces) a breeze. On top of this data, you can analyze the quality, cost and latency of LLM apps. When GPT-4 dropped, we started building LLM apps – a lot of them!

    Hi HN! I've recently been finding productivity in running parallel CLI coding agents(after not believing in them initially). After having to do a ton of git stashing and branch fumbling, I decided I needed to something to more ergonomically run these agents in their own dedicated spaces. I tried a lot of the existing products but they either were too convoluted or flat out didn't work. Some of them also seem to roll their own chat UI which I don't think is the right approach, I wanted to something to lightly wrap my terminal sessions. So I built FleetCode! It uses git worktrees and let's you…

    Hi, I built this because running multiple Claude Code agents across multiple IDE and terminal windows was getting messy. Like many, I went from working at one thing at the time, to multiple, and it was all changing quite fast. I needed one place to see all my agents and worktrees, seamlessly switch between them, monitor their status and once their done, review their changes. I also wanted to quickly spin up new agents in isolated worktrees whenever an idea came to mind. I've been building Baton from within Baton for a while now, which has been a pretty fun loop. Would love to hear what you…

    Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

    Hey HN, I’m building Databite, an open-source set of tools to help developers build integrations faster and with ease. If you’ve ever built a SaaS product or an AI agent that needed to update a CRM record, sync data between apps, or trigger a workflow in a third-party tool, you’ve probably spent way too much time writing glue code. Databite is here to be that glue. With Databite you can: - Access prebuilt connectors using the databite/connectors package. - Create custom connectors to services of your choice like Slack, Notion, HubSpot, Google Sheets, etc. using our databite/build…

    We run an open startup and believe in sharing numbers publicly. But our setup was a mess: metrics lived in Stripe and PostHog, we'd pull them manually, paste into our CMS, and embed that on the site. Every update was a chore. Every number was stale. Openboard connects directly to your data sources and generates a live public metrics page. No CMS middleman, no manual updates. Currently supports Stripe (MRR, churn, active subscribers) and PostHog (visitors, signups, retention). Adding more integrations based on what people actually need. The base version is free — sharing should be…

    Hi HN, I wanted to give my family, who are scattered all over the world, a simple and private way to connect. The commercial options didn't quite fit, and the open-source tools I found were a bit too barebones and not friendly enough for non-technical users. My main goal was to build something completely self-service. I wanted my family to be able to manage their own devices without my help, so I could set it up once and then stay out of it. This led me to build LeiaGuard, a self-hostable UI for WireGuard built with Next.js. To make it truly easy for everyone, the interface is available in…

    We just open-sourced the internal system we built at Assembled for running coding agents as a team. Coding agents worked well for individual engineers, but the surrounding workflow was a bit of a mess. We generally found that many engineers had different MCP connections and context for their agents, personal automations running that other people couldn’t access, and very little introspection for what a human’s input into the coding agent looked like. So we built an internal system that converted coding agents into shared team infrastructure. The system runs Codex, Claude Code, OpenCode, and…

    We built StripeMeter, an open-source usage metering platform that plugs directly into Stripe. It solves the classic SaaS pain of “why is my bill higher than expected?” by giving both developers and customers real-time usage tracking with live cost projections. Why it matters: - Transparency: Customers see exactly what Stripe will bill them (within 0.5% parity). - Exactly-once guarantee: No double billing, ever. - Fast & scalable: Sub-minute freshness with Redis + Postgres counters. We’d love feedback from SaaS builders, especially if you’ve struggled with Stripe’s metered billing. Does this…
