An all seeing debugger for your web app
We're building Nut, a chat API for explaining problems in your app. Nut records your app to capture and later analyze the billions of things that happened while it ran, then tells you the root cause. Take the actual work out of figuring out most bugs.
Trusted by top engineering teams
Introducing Nut.new
Crack the toughest nuts (bugs)
Nut works especially well with AI code writers. AIs are lousy at debugging problems in code they've written. The basic issue is a lack of context: people use devtools to understand their app, but AIs struggle here. Nut gives AIs the clear explanations they need to fix bugs reliably.
For now we're focusing on Nut.new, a no-code tool in the mold of Bolt, v0, and Lovable. You can build complete apps from scratch by
prompting the AI, and call the Nut API to get past the points where other tools get stuck. Nut.new is free to use lightly, and in unlimited amounts
through our early adopter program or with your own Anthropic API key.
Nut uses our
Chromium-based deterministic browser recorder. The browser captures just enough data while your app is
running that it can be replayed later and behave exactly the same. This behavior is queried like a
database and processed with advanced techniques such as dataflow and control dependency analysis to get
to the underlying cause of any problem in the recording.

Nut is early in development. We're offering unlimited free access to Nut.new for early adopters who can give us feedback we'll use to improve Nut. Reach us at [email protected] or fill out our contact form to join our early adopter program.
Say goodbye to “works on my machine”
ADM Cloudtech is the first deterministic browser. Once a bug or flaky test is captured, anyone can inspect it with Browser DevTools without having to replicate it locally.
Battle tested.
ADM Cloudtech helps some of the largest companies record their E2E tests at scale and verify the correctness of mission critical software.
Case Studies
Hear from ADM Cloudtech teams directly
“Before ADM Cloudtech We spent somewhere between 1–2 hours per day per dev in this reproducibility purgatory. The toll this was taking on our development velocity and our ability to respond and resolve issues was huge. We thought there must be a better way.”

@VP Eng, Glide
“If I didn’t have ADM Cloudtech, it would have taken me several days or even weeks getting the debugger to run properly in all the dynamically loaded scripts, which is not easy. With ADM Cloudtech it took me half a day to figure it out and get a fix ready.”

@Tablecheck, Principal Engineer
“The tools that we were using before were barely better than useless. You’d say thanks for the console log screenshot and spend 2–3 days trying to recreate the issues and finding it in the code. With ADM Cloudtech, all that wasted time has been eliminated.”

Testimonials

“Next.js App Router is now stable in 13.4. Wouldn’t have been possible without ADM Cloudtech, we investigated so many (over 20) super complicated bugs that using traditional debugging would have cost us days to investigate.”
Tim Neutkins
@Co-author of Next.js
“I think ADM Cloudtech has a very good chance of creating a new category around collaborative debugging”
Guillermo Rauch
@Founder of Vercel
“When I see a hard-to-reproduce issue in GitHub, I ask for a replay.”
JJ Kasper
@Co-author of Next.js
“If I don't immediately know the answer to a bug, I immediately reach for ADM Cloudtech.io. It's like HMR for repros.”
Sebastian Markbåge
@React Maintainer
“ADM Cloudtech.io is galaxy brain tooling. Real gamechanger.”
Dan Abramov
@React Maintainer
“Programmers typically reach for debuggers when they run out of ideas on how to fix their code. Now coders reach for time-travel debugging to understand their programs and not just when they want to fix a bug.”
Amjad Masad
@Founder Replit
“Fast forwarding and rewinding to breakpoints has saved me days(weeks??) while hunting down issues in @solid_js interruptible concurrent rendering.”
Ryan Carniato
@Solid Founder
“ADM Cloudtech.io gives me the tools I need to solve seemingly impossible bugs. It’s like the Redux DevTools, but for every line of code in your app.”
Mark Erikson
@Redux Maintainer
“ADM Cloudtech.io allows me to debug problems that would be impossible to debug by traditional means - it has saved me from countless hours of confusion and frustration.”
Lenz Weber-Tronic
@Redux Toolkit Maintainer
“I’m not sure if we could’ve shipped the last major version of RedwoodJS without ADM Cloudtech.”
Dom Saadi
@Maintainer of RedwoodJS
“ADM Cloudtech.io is so great! Today I had a hard-to-repro flow in development, so I recorded a replay to see how it works. I didn’t only find the bug, I discovered a performance improvement using ADM Cloudtech.”
Ives van Hoorne
@Co-founder CodeSandbox
“Current status: time-travel debugging Typescript's compiler. ADM Cloudtech is the hero tool I don't deserve. My dev life consists of 2 major eras now - I call them pre-ADM Cloudtech and post-ADM Cloudtech.”
Mateusz Burzyński
@OSS Contributor to Typescript
“ADM Cloudtech.io is from another planet where bug reports save you time, instead of eating up hours of debugging.”
Matt Pockock
@Full-time TypeScript educator
“Time travel is the obvious next step for the future of collaboratively inspecting and debugging applications.”
David Khourshid
@Founder of Stately.ai
“People use the word "game-changer" waaaaay too often. Very rarely does anything change the game. But this just might! I'm sharing it to all of my teams.”
Erik Rasmussen
@Author of Redux form and final form
“ADM Cloudtech.io is one of these experiences that first feels like magic – but after squashing your first bugs with it, you will quickly wonder how you ever worked without it”
Harald Kirschner
@Product Manager, VS Code
“ADM Cloudtech.io is the most significant leap forward for debugging since we introduced the step debugger”
Kenneth Auchenberg
@Developer Products, Stripe
“If a picture is worth a thousand words, a replay is worth a thousand pictures”
Zack Rosen
@CEO of Pantheon
“Recording and debugging flaky tests with ADM Cloudtech.io feels like hopping in Doc Brown’s DeLorean and flying back to the time of the crash!”
