The problem
Not the loop that caused it.
Provider bill jumped $412 overnight. Which feature did this?
3,800 calls to the same model in 6 minutes.
Upstream timeout. Every request retried 5 times. Spend tripled in an hour.
Each agent step resent the whole history: 31k tokens per call and climbing.
Last updated 4 hours ago.
A top-tier model answering “what are your hours?” 9,000 times a day.
“I set max_retries to 50 so it never fails 🙂”
The spreadsheet forecast assumed linear growth. It wasn’t.
Arrived after the budget was already gone.
Loop caught at call 4, not call 3,800.
Illustrative examples, not customer data.
Features
See where the money goes, catch what's going wrong, and stop it while it's still happening.
See which model, feature and workflow every dollar goes to, across 13 AI providers.
A Monte Carlo forecast shows your likely month-end bill and the bad case, not one straight line.
Alert, slow down or block one feature, or a whole workspace, when it crosses limits you set.
Catches retry storms, repeated calls and context that keeps growing. A repeated call is flagged after 4 in a row.
I'm the founder, and I'd like to help you get AtlasBurn running in your app.
Book a call and we'll set it up together, or just tell me what your AI costs look like today.
Setup
Your existing OpenAI, Anthropic and Gemini calls are picked up automatically. No code to rewrite.
abn init finds your framework and env file, shows exactly what it will change, and asks before writing anything.
abn init
# 1. Install the SDK (the abn CLI comes with it) npm install @atlasburn/sdk # 2. Run the setup wizard in your project root npx abn init
Optional: tag a call with its feature to see cost per feature.
import { atlasburnFeature } from "@atlasburn/sdk"; await openai.chat.completions.create(params, { headers: atlasburnFeature("support-chat"), });
Connect AtlasBurn in Claude or any MCP client, then ask it to set things up.
YouSet up AtlasBurn in this project.
Python, Go, Ruby or anything that makes HTTP calls: point your OpenAI, Anthropic, Gemini or OpenRouter base URL at the AtlasBurn proxy. Guardrails then apply at the edge, before the request reaches the provider.
Provider & framework support
13 AI providers detected automatically by the SDK, including the six below plus Azure OpenAI, Vertex AI, Groq, DeepSeek, xAI, Together AI and OpenRouter.
Providers
Frameworks
The SDK runs in Node.js and TypeScript. Python, FastAPI and other languages connect through the AtlasBurn proxy (OpenAI, Anthropic, Gemini and OpenRouter).
Safe by design
So it's built to never get in the way.
Only usage numbers: model, tokens, cost, time and the feature label you choose.
The SDK and the gate fail open. If we can't be reached, your AI calls go through as normal.
A loop in one feature slows down that feature. The rest of your product keeps running.
Alert only, slow down, or block. Loops are slowed down first and blocked only if they keep going.
We keep only a one-way hash of your AtlasBurn keys, and never store your AI provider keys.
Export it, clear it, or delete your account and everything in it, any time from Settings.
Where we are
AtlasBurn is in free beta. Here's what's real today.
Ask Claude about your AI spend, or have it set AtlasBurn up for you. Listed since October 2026.
24
In Claude since our directory listing, from Claude's connector dashboard. Small, and growing.
Read exactly what runs in your app. Apache-2.0.
Part of Google for Startups and Google Cloud for Startups, and Anthropic's Claude for Startups program.
No customer logos or quotes yet, because we won't make them up. When our first teams tell us AtlasBurn saved them money, their words will go here.
