24 alternatives to Deadlog – almost drop-in mutex for debugging Go deadlocks
I've done this same println debugging thing so many times, along with some sed/awk stuff to figure out which call was causing the issue. Now it's a small Go package. With some `runtime.Callers` I can usually find the spot by just swapping the existing Mutex or RWMutex for this one. Sometimes I switch the mu.Lock() defer mu.Unlock() with the LockFunc/RLockFunc to get more detail defer mu.LockFunc()() I almost always initialize it with `deadlog.New(deadlog.WithTrace(1))` and that's plenty. Not the most polished library, but it's not supposed to land in any commit, just a temporary…
Deadlog is a Go package that helps developers debug mutex deadlocks by serving as a drop-in replacement for standard Mutex or RWMutex. It uses runtime call tracing to identify which code is causing lock contention… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. https://jam.dev It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer…

I wrote this Go project to implement a dead man’s switch that didn’t rely on cron jobs, timers, databases, etc on the infra it runs on. Deadcheck integrates to PagerDuty and keeps a long running incident snoozed until expected check-in times where it’ll alert unless a check-in occurs.

superlog▲497Hey HN, we’re Nico and Arseniy, co-founders of Superlog (https://superlog.sh). We're building a self-installing, self healing observability tool meant not to be opened. It has a wizard that daily sets up proper logging and an agent that investigates errors and opens PRs. Super short demo: https://www.youtube.com/watch?v=xFhU9Mk247M. In our earlier startups, we tried Sentry, Datadog, Grafana, Dash0, and nothing was good enough. Proper telemetry and alerting still requires a ton of manual setup. We struggled with adding good logs, so debugging was tough, especially as…

Hey HN, the is Chris, creator of FireDBG. We’ve been working on this debugger just about a year now. Time travel debugging isn’t a new concept, the new idea here is to use call tree visualisation to help us navigate the debug trace. It supports various Linux distros on x64 and macOS on x64 and M1. It’s only available for Rust right now, but we do want to bring this debugging experience to other programming languages. Please give it a try! Would love to know your thoughts. What’s your anecdote in debugging programs? My stupidity is usually in the form of: after a few hours of debugging, I…

Hey! We are presenting CodeTracer - a user-friendly time-traveling debugger designed to support a wide range of programming languages: https://github.com/metacraft-labs/codetracer?tab=readme-ov-f... CodeTracer records the execution of a program into a sharable self-contained trace file. You can load the produced trace files in a GUI environment that allows you to move forward and backward through the execution and to examine the history of all memory locations. They say a picture is worth a thousand words — well, a video is even better! Watch the demo below to see…

Hello HN! Parth, and Shardul here. We have been building unlogged.io for the last 21 months. We started as a time travel debugger and pivoted to record and replay with assertions, mocking, and code coverage. You can save the replays in the form of a JSON and commit them to your git. Both Parth and I come from an e-commerce/payments background where production bugs meant heavy financial losses. Big billion days/Black Friday sales meant months of code freezes with low productivity. Before committing the code, we wanted to replay production traffic and know the breaking changes right…

Hi All, this is Shardul here - I am the co-founder of Videobug. https://bug.video We are super excited to share Videobug with you. Videobug records run time code execution so that developers can watch it line by line as frequently as they want, right in their IDE. It takes away the pain of recreating exact conditions that led to a bug and saves developer time in every bug squash. Parth (my co-founder) and I have worked on multiple production grade applications in startups and enterprises. We used Logrocket, Sentry, and Datadog for logging and found ourselves adding more logs after…

Debugging a crash can sometimes feel like a noir detective story: following faint clues, chasing red herrings, and eventually hitting the moment where the whole case finally makes sense. I leaned into that idea and built Fatal Core Dump, a small game where the investigation is real crash debugging. The game gives you a Linux binary, its core dump, a source file, and some logs. You solve the mystery by debugging it. The premise: an engineer dies when an airlock on an asteroid mining station opens unexpectedly. Your job is to determine whether it was a simple software bug or something more…

Hey HN, I tend to use printf-style debugging as my primary troubleshooting method and only resort to gdb as a last resort. While I like its ease of use printf debugging isn't without its annoyances, namely removing the print statements once you're done. I used to use trace-level logging from proper logging libraries but adding trace calls in every corner quickly gets out of control and results in an overwhelming amount of output. To scratch my own itch I created dlg - a minimal debugging library that disappears completely from production builds. Its API exposes just a single function, Printf…

This project is inspired by some of the asserts in Unreal engine. Due to reliance on core_intrinsics it is necessary to develop using nightly Rust, but there are stubs in place so a production build will not require nightly. I recently released version 0.2 which includes no_std support and adds optional log message arguments to the ensure macro.

Hey HN, this is Will and David from Fortress (https://news.ycombinator.com/item?id=41426998). We use a lot of async Rust internally, and created this library out of a need for an async-aware concurrent hashmap since there weren’t many available in the Rust ecosystem. Whirlwind is a sharded HashMap with a fully asynchronous API. Just as dashmap is a replacement for std::sync::RwLock, whirlwind aims to be a replacement for tokio::sync::RwLock. It has a similar design and performance characteristics to dashmap, but seems to perform better in read-heavy workloads with tokio's…

Hi HN, I built goxe, a tool designed to tackle one of the most annoying (and expensive) problems in infrastructure: log spam. When a service starts failing, it often floods your pipeline with thousands of identical log lines. This doesn't just create noise; it increases bandwidth usage and inflates storage costs in platforms like Datadog or Splunk. Goxe sits in your pipeline (currently via Syslog/UDP), normalizes incoming logs by stripping timestamps and variable noise, and aggregates them in real-time. Instead of 10,000 lines of the same error, you get one line with an occurrence…
