Same models. Better engineering.

We use the same AI models everyone else does. The difference is what we built around them.

Compared against Claude Code, Cursor, Cline, Kilo Code, and Copilot

Under the hood

Engineered, not wrapped.

Every feature exists because generic AI tools got it wrong.

Per-Model Intelligence

Haiku optimized for speed. Opus for deep reasoning. Gemini for massive context. Each model runs at its absolute peak — not one-size-fits-all.

Build-Verify-Fix Loop

Writes all files, installs deps, runs build, reads errors, fixes them, rebuilds. Repeats until zero errors. Autonomously.

33 Purpose-Built Tools

File ops, search, git, web research, LSP, sub-agents, batch operations, 55+ framework scaffolds. Not a wrapper — an engineering platform.

Garbage-Free Output

Filters robotic narration like "let me check" and "I'll now..." — you only see real, meaningful output. Clean terminal.

Session Persistence

Auto-compacts at 95% context. Resumes after interruptions. Your work survives crashes, disconnects, and model switches.

60% Reading, 40% Writing

Reads your codebase first — structure, conventions, configs. Then writes code that actually fits. Like a real senior engineer.

How it works

One prompt in your terminal. Five steps. Working code.

01

Understand

Reads your project structure, dependencies, and code patterns.

02

Plan

Breaks your request into concrete, executable steps.

03

Build

Writes all files — components, styles, configs — in one pass.

04

Verify

Runs the build, reads errors, fixes them, rebuilds until clean.

05

Ship

Clean build, zero errors. Ready to deploy.

Multi-Model

11 models. 3 providers. One terminal.

Developers who switched aren't going back

From indie hackers to startup engineers — builders who tried Claude Code, Cursor, and Copilot chose Synoppy.

Prompted a full Next.js dashboard with auth, dark mode, and a settings page. Clean build on first try. I literally just deployed it. Took 8 minutes.

@arjunbuilds

Full-stack Developer

The multi-model thing is actually useful, not just marketing. I use Haiku for quick refactors because it's fast, Sonnet for new features, and Opus when I'm architecting something complex. Switch with /model, keep the same context.

R

Rachel Kim

@rachelcodes

Senior Engineer at a YC startup

Switched from Cursor. No regrets. Terminal-native, BYOK so I use my own API keys with zero limits, and it actually runs my build and fixes errors. Cursor never did that.

D

Dev Patel

@devpatel_

Indie Hacker

I asked it to build a portfolio. It scaffolded Next.js, wrote 7 components, installed framer-motion, ran the build, got 2 type errors, fixed both, rebuilt. Clean. All I did was type one sentence.

S

Sofia Lindgren

@sofialdev

Frontend Developer

The build verification loop is what makes this actually different. It doesn't just generate code and hope — it compiles, reads the errors, fixes them, and rebuilds. That's not a suggestion engine. That's an engineer.

M

Marcus Thompson

@marcust_dev

Tech Lead

Tried Claude Code, Cursor, Copilot, Windsurf. This is the first tool where I describe a feature and get back a working result without touching a single file. The 50% launch deal makes it a no-brainer.
