Your agent, monitored.
From local testing to enterprise deployments, Raindrop has you covered.

Trusted by engineering teams at

One workflow, every surface
Every production run leaves a trail of messages, tool calls, retries, and errors. Raindrop captures it all in one place.
One workflow, every surface
Every production run leaves a trail of messages, tool calls, retries, and errors. Raindrop captures it all in one place.
Raindrop reads the trace and sends the real failures to Slack, from hallucinations and loops to broken tools.
Just like a teammate, Raindrop lives in Slack. Ask questions, triage issues, create signals, and more.
Ship the fix, run an experiment against live traffic, and confirm the regression is gone for good.
Here's what developers building with Raindrop are saying

@ardabrowski
Hey this is awesome! Finally a product where you can "look at your data" in a beautiful way, not just a soulless dump of jsons for nerds. I've been building sth along those lines for customer support (not observability, and not as polished). I display convo history as blocks, similar to Notion, and you get notion-like collaboration too for feedback. Is this possible in raindrop?

@amasad
If you're building an agent, I recommend looking into Raindrop for monitoring. We use it.

@Jeremy_JFischer
I’ve been using this all day today. Soooo much easier to iterate. Spans, token count, cost, timing, a sane view of each tools input-output.

@jxnlco
Heard it works with your codex subscription. Now you can use codex to build agents as well as inspect them I tried it out yesterday and it works great in the in app browser of the codex desktop app

@banisgh
Observability needs to be more actionable. Raindrop was already one of my most used tools and it just keeps getting better (!)

@reiddraper
absolute 🔥, all other trajectory viewers are unusable in comparison

@HamelHusain
Really like the UX/data viz in some of these Increasingly important for sorting through multi-agent / parallel workflows to tame the trace spagetthi

@benhylak @raindrop_ai We recently got an influx of users from China and used Deep Search to make a classifier for "the user speaking chinese" this morning. Raindrop translates them, so we're able to get to know a group of users we'd otherwise have no insight into. Feels like I'm living in the future

@devstein64
loved the onboarding experience

Jake Colling
@JacobColling
Very good. Immediately useful. Going to be using this as default for local agent work now Also looking at instrument Claude code sessions with it to improve skills etc
Danny Aziz
@DannyAziz97
@aviflombaum I’m a huge fan of @raindrop_ai for agent monitoring
Scott Stevenson
@scottastevenson
@jmwind @benhylak We are loving Raindrop!
Jake Colling
@JacobColling
This is very well done. Built in chat that plugs into your local codex/claude is perfect. Need someone to make this for general otel too
Pratyush Rai
@pratyush_r8
This is insanely cool. 🔥🔥 One of the best products out there (by far) for anyone building agents just released an OSS version to play with. We’ve already been using Raindrop heavily across Thine / Merlin. Excited to now use it across personal projects too.
Mitch
@mitchellhynes
Spellbook has been using this for weeks and it feels like magic. It raises silent bugs daily. Feels like my agent is a team member that advocates for itself telling us the most important bugs for us to fix.
Rob Haisfield
@RobertHaisfield
Raindrop feels like extremely futuristic software. It lets you explore user intent and agent trajectories in a way that didn't feel possible years ago. Big fan of them. Every part of what they've built is thoughtful, solving design problems for a new kind of observability.
Sam Whitmore
@sjwhitmore
once again the @raindrop_ai is ahead of the curve…imagine searching for expensive, error prone, or slow tool calls across all your agent traces. nothing like this exists yet
Evan Goldschmidt
@evangoldschmidt
@tolanworld runs on raindrop. highly recommend
austin petersmith
@awwstn
just made a feature request for @raindrop_ai and they shipped it in less than 3 hours

Peter
@peter58587
This is actually incredible. I've been building out a project that involved running Pi in a cloudflare container, it's been a nightmare locally to try and get decent observability on what's happening and to get a feedback loop going. This really came at the perfect time!

Nikita 🤙
@Hormold
nice, it works awesome for voice agents too!
Guillermo Rauch
@rauchg
@benhylak @raindrop_ai awesome
Jean-Michel Lemieux
@jmwind
@benhylak Big fan of raindrop ! 💪🏼
nader dabit
@dabit3
Such a nice idea. we need this for @DevinAI for Terminal @MattSchrage @alexkaplan0 👀

@walden_yan
Agents finding bugs in agents and tagging another agent to fix those agents Welcome to the singularity
Stew Fortier
@stewfortier
It's difficult to overstate how insanely useful @raindrop_ai is, and it just keeps getting better

@titanas
Raindrop will be remembered as the company who did to AI infra what the Mac did to the personal computer. It’s a matter of time until frontier labs recognize the value and make a move.

Happy customers

@JustinBleuel
Easily my favorite tool to discover, analyze, and solve agent issues @clay

This is awesome We @lexdotpage are very happy customers of @raindrop_ai!

Congrats on the launch! Have been building many versions of this from scratch for various projects, and now I can finally use a unified tool for it.
