Every AI coding tool I've used has the same problem.
It suggests code. I copy-paste it. I wire it up. I fix the imports. I run the build. I debug the errors. The AI did 20% of the work. I did 80%.
I got tired of being the AI's assistant. So I built one that does the full 100%.
Meet Synoppy
Synoppy is an AI coding agent that lives in your terminal. Not a copilot. Not a chatbot. An autonomous agent that reads your codebase, writes every file, installs dependencies, runs the build, fixes its own errors, and ships.
One prompt. Full project. Clean build.
> Build me a SaaS landing page with pricing, testimonials, and dark mode
Scaffold(Next.js 15 + Tailwind v4)
Write(Navbar.tsx) 87 lines
Write(Hero.tsx) 124 lines
Write(Pricing.tsx) 203 lines
Write(Testimonials.tsx) 142 lines
Write(Footer.tsx) 96 lines
Write(globals.css) 284 lines
Bash(npm install) added 12 packages
Bash(npm run build) 0 errors
Done in 6m 42s — 8 components, production-ready.
That's real terminal output. Not a mockup.
The Problem With Every AI Coding Tool
GitHub Copilot autocompletes one line at a time. Great for boilerplate. Useless for building a feature end-to-end.
Cursor is better — it edits files and understands context. But you're still the orchestrator. You decide what to do next. You run the build. You read the errors. You tell it what to fix.
ChatGPT/Claude chat gives you code blocks. You copy. You paste. You pray it works. It never does on the first try.
Here's what I wanted: describe the outcome, get the outcome.
Not "here's some code, good luck." But "here's your working app, build passes, zero errors."
That's what Synoppy does.
How It Works Under The Hood
When you give Synoppy a prompt, here's what actually happens:
Step 1 — Understand. It reads your project structure, package.json, existing components, and config files. It knows what framework you're using, what dependencies you have, and how your code is organized.
Step 2 — Plan. For complex tasks, it creates a structured plan with tasks. You can review and approve before it starts building.
Step 3 — Build. It writes ALL the files. Not one at a time — everything. Navbar, Hero, Pricing, Footer, globals.css, layout updates — all in one pass.
Step 4 — Wire. It installs the specific packages it needs. Not npm install — it runs npm install framer-motion lucide-react with exactly the dependencies its code uses.
Step 5 — Verify. It runs the build. Reads every error. Maps errors to files. Reads those files. Fixes them. Rebuilds. Repeat until clean.
Step 6 — Ship. Clean build, zero errors, ready to deploy.
The entire loop is autonomous. You describe what you want. You get a working result.
12 Models From 3 Providers
Most AI tools lock you into one model. One provider. One price point.
Synoppy gives you 12 models from 3 providers. Switch mid-conversation with /model:
Claude (Anthropic)
- Opus 4.6 — most intelligent, 128K output, adaptive thinking
- Sonnet 4.6 — best speed-intelligence balance
- Sonnet 4.5 — reliable workhorse
- Haiku 4.5 — fastest, great for quick edits
Gemini (Google)
- 3.1 Pro — deep reasoning
- 3 Flash — fast and affordable
- 3.1 Flash-Lite — cheapest option
DeepSeek
- V3 — $0.14 per million input tokens
Use DeepSeek for quick questions. Sonnet for everyday coding. Opus for complex architecture. Switch freely.
33 Tools, Zero Plugins
Synoppy has 33 built-in tools it uses autonomously:
File operations — read, write, edit, multi-edit, delete, move, copy, undo
Search — glob, grep, search and replace, explore entire directories
Build and run — execute commands, scaffold 55+ frameworks, verify builds, batch operations
Git — status, diff, commit, branch, log — all without leaving the conversation
Planning — structured plans with tasks, persistent todos, clarifying questions
Web — search the web, fetch URLs for documentation
No plugins to install. No extensions to configure. Everything works out of the box.

Some Technical Decisions I'm Proud Of
Fuzzy matching for edits. When the AI generates old_content that doesn't exactly match the file (whitespace differences, minor changes), most tools fail silently. Synoppy tries 5 strategies: exact, full replacement, normalize line endings, trim whitespace, and anchor-based matching.
Build verification loop. The agent doesn't trust itself. After writing files, it runs the build, reads every error, traces errors to specific files, reads those files, applies fixes, and rebuilds. This loop continues until the build is clean.
Prompt caching. Anthropic's prompt caching saves 60-80% on input tokens for repeated API calls in the same conversation. We place cache breakpoints on the system prompt and last tool definition.
Max tokens recovery. When a model runs out of output tokens mid-file-write, Synoppy repairs the incomplete JSON, saves what it can, and continues seamlessly in the next API call. No data loss.
Adaptive thinking. Claude Sonnet 4.6 and Opus 4.6 support adaptive thinking — the model decides when to think deeply vs. respond quickly. Budget-capped at 25% of output tokens so it doesn't burn your credits on reasoning.

I built this because I believe AI should do the work, not just suggest it. If you try it, I'd love to hear what you build. Drop a comment — I read and respond to every one.
