For the last 5 months, I’ve been working on Hazel, and I’m super excited to finally share a first open beta version: https://t.co/sLSH97LNCc, try it out now!

Fully open source as always of course https://t.co/fPH9stf18Z

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.

@danieljvdm How much did it take to overload?

[Makisuo @makisuo]

@danieljvdm oh very cool 👀 will give it a try!

what's your experience with maple local so far? anything missing?

[Makisuo @makisuo]

2026 truly is the year of @EffectTS_

[vimtor @vimtor]

first time working on an @EffectTS_ codebase and i already fell in love

i don't know if it's the guardrails or the spell it cast on the model, but i'm oneshotting stuff like never before

[Makisuo @makisuo]

@jakemor NGMI smh

[Makisuo @makisuo]

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

[Makisuo @makisuo]

@bleuonbase Really appreciate it! Would love to make it MIT someday, but yeah just having it as FSL licensed right now since im the tiny new fish in the pool 😅

[Makisuo @makisuo]

All of Maple is of course also Opensource, and Local mode can easily be used without needing an account, nor even using Maple itself https://t.co/LI5kPvlpnh

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

@Shyim97 it's all open source, feel free to dockerize the binary if you like 👀

@Shyim97 You don’t even need docker! It’s just one binary

[Makisuo @makisuo]

@scavenger869 lemme know if you have any wishes or feedback!

[Makisuo @makisuo]

@jakemor Time to build Superbrowser

[Makisuo @makisuo]

@Necmttn Very cool love it!

[Makisuo @makisuo]

@samuellhuber I’m working on a local version, will release it soonish for exactly this use case

[Makisuo @makisuo]

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

[Makisuo @makisuo]

@yoeven @nooriefyi What scale are you running on? I have a worker doing 2k req/s without any issues

[Makisuo @makisuo]

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

[Makisuo @makisuo]

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
