You build with AI. Composure makes sure it's built right.
Security checks, testing, and code organization — handled automatically, so you can focus on your product.
It works when you test it. Then real customers show up.
You build a SaaS with AI, click around, and launch it. Then two customers log in at the same time — and see each other's invoices. The AI never wrote the rule that keeps their data apart. It looked done. It wasn't.
Professional developers add security checks, automated testing, and deploy safeguards to every project. AI skips all of it unless you know to ask — and most people don't know to ask.
63% of AI-generated apps launch with security holes that professional tools would catch automatically. Vibe-coding security research, 2026
What AI doesn't tell you
It doesn't check for security holes
AI writes code that works — but it doesn't scan for vulnerabilities, hardcoded secrets, or injection patterns. Those go live silently.
It doesn't test if things actually work
Your app runs today. But will it still work after the next change? Without tests, you're guessing. AI doesn't write tests unless you ask.
It doesn't organize your code for the long term
AI puts code wherever is convenient right now. After a few weeks, your project becomes a maze that even AI struggles to navigate.
It forgets what it built yesterday
Every conversation starts fresh. AI doesn't remember your project structure, your architecture decisions, or what it already built.
How Composure handles this
Scans every change for vulnerabilities
Security issues are flagged the moment they're written — not after you launch.
Writes tests that match your project
Reads your existing code style, then generates tests that look hand-written.
Enforces clean architecture
Prevents messy code patterns automatically. Your project stays organized as it grows.
Remembers your entire project
A knowledge graph indexes every file, function, and connection. Nothing is forgotten between sessions.
The invoice leak, caught before it launches.
You ask your AI to build customer logins. It writes code that works — but skips the rule that keeps one customer's data from appearing in another account.
Composure's security scan, in plain English: “This table has no policy isolating customers from each other. Any signed-in user could read every row — including other customers' invoices.” Then it adds the missing rule.
You didn't have to know the rule existed. That's the point.
It tells you in plain English.
Not "RLS policy violation on public.invoices." A sentence: "This table has no rule keeping customer data separate. Anyone logged in could see everyone’s records."
It shows you exactly where.
The file, the function, the line. Not a report to interpret — a precise pointer you hand straight back to Claude.
It fixes it — you just approve.
Composure surfaces the fix. Claude applies it. You review one sentence and confirm. You don’t need to understand the underlying rule — just that it’s now enforced.

Why Claude Code?
Claude Desktop is great for conversations. But building real applications needs a professional workspace. Claude Code is that workspace — and it's still just typing in plain English.
The difference: Claude Code works directly with your project files, remembers your codebase structure, and can run tools like Composure that enforce quality automatically. Same AI — but now it has professional tools.
Claude Desktop
Chat about code. Copy-paste files. No project awareness. No enforcement.
Claude Code + Composure
Works inside your project. Knows every file. Security scans on every change. Quality enforced automatically.

Install Claude Code
Claude Code is the professional version of Claude for building software. It runs in a terminal window, but you still just type in plain English — same as Claude Desktop.
You need: a computer (Mac, Windows, or Linux) and a Claude subscription. The install opens a terminal window, but you only ever type plain English into it — the same as Claude Desktop.
New to the terminal after the Claude Desktop app? You're not stuck in it — the free Control Panel gives you a visual cockpit for your sessions, reviews, and code graph, all on one screen. Only the Campaigns tab asks for PRO.
