Start in seconds

Atmos installs with one command on macOS, Linux and Windows. The scan runs the full managed ruleset with nothing to set up.

curl -fsSL https://atmoslab.dev/install.sh | bash

The installer opens a link in your browser. Sign in, approve, and your terminal is signed in.

Run the first scan

atmos scan . checks code and dependencies in one run. Findings show in your terminal and on the platform.

Scan in under a second

Atmos rescans only what changed and usually returns the findings in under a second. A rescan of a repository with 2 million lines of code finishes in less than 3 seconds.

For coding agents

Coding agents write more code than most teams can read. Atmos rescans after every agent turn and hands the findings back to the agent that fixes what it just wrote before moving on.

❯ Add an optional ?status= filter to GET /orders in src/routes/orders.ts, the way products.ts does. ● I'll add the status filter to the orders route. Let me first check how it's implemented in products.ts. Searched for 4 patterns, read 3 files (ctrl+o to expand)● Now I'll update orders.ts to add an optional status filter using the same whereEq pattern.● Update(src/routes/orders.ts) ⎿ Added 5 lines, removed 1 line 1 import { Request, Response, Router } from 'express'; 2 import { db } from '../lib/db'; 3 +import { whereEq } from '../lib/sql'; 4 5 export const orders = Router(); 6 7 async function listOrders(req: Request, res: Response) { 7 - const sql = 'SELECT id, total FROM orders'; 8 + const where = req.query.status 9 + ? whereEq('status', req.query.status as string) 10 + : ''; 11 + const sql = `SELECT id, total FROM orders${where}`; 12 const { rows } = await db.query(sql); 13 res.json(rows); 14 }● Done. Added the optional ?status= filter to GET /orders. When the query param is provided, it filters results by status.

For human developers

A finding in a CI report comes after the code has left the editor. Atmos scans on every save in VS Code and Cursor and underlines each finding in the editor.

Input traced across files

Untrusted input enters in one file and the dangerous call may sit in another file. Atmos follows the input across every file and reports each step with file and line, in JavaScript, TypeScript, Java and C#.

call path from your code reachable vulnerability unreachable · low priority

Only reachable vulnerabilities

Most known vulnerabilities in your dependencies sit in functions your code never calls. Atmos reads your npm, Maven and NuGet lockfiles with your source and checks whether your code can reach each vulnerable function.

Atmosphere Platform

Findings from every developer machine and every CI run land in one place. Your team triages them there and sees what each pull request changed.

Your data

Atmos is rule based, with no AI model anywhere in the scan, so the same code gives the same result, every scan. Atmos never sends your code or the findings to an AI company.
