For the last 5 months, I’ve been working on Hazel, and I’m super excited to finally share a first open beta version: hazel.sh, try it out now! Fully open source as always of course github.com/HazelChat/hazel I started building Hazel because I’ve been super unhappy with work chat apps for quite some time. Slack feels lacking in a lot of areas, customization support feels limited, Discord is amazing but sadly feels way too unprofessional, and I don’t even want to talk about Teams… I knew it would be a fool’s task to try to build something to replace these tools, but I wanted to try anyway and quickly got obsessed. I kept grinding on it more and more, slowly chipping away at one thing after another, and I can finally say I’m happy enough to use Hazel over any of the other solutions for my day‑to‑day communication, it's far from perfect but in a state I would love to get some feedback to make this truly the best communication platform. I built Hazel from the ground up with @EffectTS_ , @ElectricSQL , and @tanstack db to not only make it really, really fun to develop, but also great to use and maintain. For now, some core features include: - Public / Private / DM channels - Threads & replies - Reactions & file uploads -A media explorer - A smart notification system …and much, much more. Hazel is far from done, but I hope I can inspire some of you to join me on this journey to do the impossible and build the Slack of the modern era.

Maple has now the entire OTEL spec versioned and will auto recommend and fix any spec issues and similar In this case it automatically can map the deprecated attribute for you. Or let an agent access all recommendation via the MCP and fix it in code for you.

Maple now has experimental light mode support for all of the light mode enjoyes out there

Didn't think Maple would hit 1000 stars anytime soon, this came more unexpected then anything else. Really really appreciate all of the feedback and support github.com/Makisuo/maple

Guess I should post more of my service map improvements i do 😅

All types of databases, Redis, Postgres, Clickhouse, Mysql etc. now display important stats and metrics aswell as most run queries in the Maple service map

Maple now shows you recommendations to remap your otel span attributes with a one click apply. Maple now fixes your badly annotated spans for you

2026 truly is the year of @EffectTS_

All of Maple also gets tracked and observed on Maple. Here are a few dashboards I use to track Query Engine and Ingest service perfomance

All of Maple is of course also Opensource, and Local mode can easily be used without needing an account, nor even using Maple itself github.com/makisuo/maple/

Announcing an early release of Maple Local. The local, free OTEL Dev tool you and your agent have been looking for. It allows you to simply start a local running OTEL pipeline to work locally without needing a super heavy container and start ingesting in seconds. Includes a lot of CLI commands for your agent to hook into to debug traces, logs and even includes Browser session (If using Maple Browser Sessions), as well as a UI to debug visual. Give it a try, it's fully free and works offline maple.dev/docs/local-mode/

I'm releasing my favorite feature I have ever build to Maple soon. Browser Sessions automatically connected to backend traces. I have been using it for a few days now to work on Maple and it's truly amazing, you will be able to easily see what went wrong in a specific user session with more context than before of just having the trace, BUT the biggest unlock here is that your agent now has the full e2e context to debug production issues. Just drop Claude/Codex "Please look at user_id last 2 sessions and see what errors they ran into, return me the traceId". It truly feels like magic

Maple's overview dashboard now shows some extra service health data. Making it easier to see overall system health in one place

Maple gives you a lot of different options to visualize and explore a trace for any use case. Debugging an error? Use the waterfall. Debugging perfomance issues? Use the timeline. Exploring the executing order or debugging retries? Use the flow view

Something really cool coming to Maple soon. Automagically record Browser Sessions and auto link them to backend traces

Maple had over 100 sign ups yesterday, still can't believe it

Now when clicking on Service details in maple there is a new dependency section giving an overview over all 3rd party services
