Vibe-code
without the panic.

Every prompt is a save point. A built-in security scanner catches the stuff that wrecks weekends. Undo is a time machine, not a hope. Ship weird ideas at 2am knowing you can rewind any prompt.

Why Decalyst

The AI coding tool that actually has your back.

Not just autocomplete. A full pipeline of specialized agents, safety checks, persistent memory, and a canvas, all working together.

⏰

Undo anything, forever

Before the AI touches a file it snapshots everything. After, you get a diff receipt. Undo AI and Restore buttons survive restarts, crashes, and the AI yeeting your codebase into the void.

🛡

Built-in security scanner

A 20-point audit covering unprotected routes, hardcoded secrets, SQL injection, XSS sinks, command injection, and CVE matches. Run /vibe-scan before launch. Exact file, exact line, the fix.

🧠

Memory that actually works

Per-agent and shared project memory built on hybrid full-text plus vector search. Paste a URL once (docs, internal runbooks, your README) and the agent quotes the exact sentence that matters three weeks from now.

⚡

Tiered context, nothing wasted

Intent is read before a single token is spent. Quick question? Minimal slice. Complex feature? Full context. Tool results the size of a novel get a tight preview and a pointer.

💰

Tiered model cascade

The planner picks the cheapest model that can do each step. Boilerplate goes to GPT-5 Nano. Auth, payments, crypto, and architecture sit on Sonnet 4.6 or Opus 4.7. Same output, fraction of the cost.

📝

Inline code review

The reviewer leaves comments anchored to specific lines, visible as a soft overlay. Reply in context. The agent picks up the thread. Like Google Docs, not a terminal.

🎨

Canvas + design system

Infinite canvas for screens, flows, and sketches. Draw wireframes, convert to screens, connect with flow edges. A design wizard generates a token system your codebase can consume.

🔒

Skills you write yourself

Every built-in behavior lives in a Markdown file. Override any of it by dropping your own into .architect/skills/. Skills auto-activate on file patterns.

📡

MCP, persistent connections

List your MCP servers once. They appear as first-class tools in every agent. Connections stay alive for the whole session.

🔑

BYOK at zero markup

Bring your own Anthropic, OpenAI, or OpenRouter key on any tier and pay provider rates, no Decalyst markup. Your subscription still works, credits still track for visibility, power users escape the toll booth.

🚀

Finishes the job

Detects your project type, runs install + build, fixes failures automatically. Live preview in the IDE. Download ZIP, push to GitHub, or export as Docker. One button each.

👥

Real-time team sessions

Invite via P2P link, no login required. You both see the AI work as it happens. Hand off mid-feature without losing context. End-to-end encrypted. Available on every tier.

The pipeline

Every prompt through a full team.

Not one model. A chain of specialists, each owning their domain, each with a written persona you can read and override.

Memory Keeper feeds context throughout. Debugger runs on-demand when tests fail.
