Show HN: IDE for code assembly of resuable code blocks
Tetrees is an IDE that lets developers assemble reusable code blocks—like the game Tetris—to handle common pain points (auth, payments, admin, backend overhaul). It offers over 500 code-block products (some paid, mostly free) with KYC verification, upvotes, and reviews to guard against malware. New users get 400K free tokens upon sign-up.
Background
- Tetrees is a new IDE (integrated development environment) that lets developers assemble apps by combining pre-built "code blocks" — think of it like a marketplace of reusable components (auth, payments, admin panels, etc.) that you can snap together visually, similar to how Tetris fits blocks together.
- "Vibe coding" is a recent term (coined by AI researcher Andrej Karpathy in early 2025) for using AI assistants like ChatGPT to generate code by describing what you want in natural language, rather than writing it manually.
- The key pain point Tetrees addresses: even experienced devs find tasks like adding payment systems or admin backends tedious, and vibe-coding AI often produces messy or insecure code for these parts.
- The platform includes a marketplace with 500+ code blocks (some paid, most free) and uses "KYC verification" — a real-world ID check, like what crypto exchanges use — to prevent malicious actors from sneaking malware into shared code.
- 400K tokens refers to a free trial allowance of AI processing power (tokens are the units AI models use to measure text input/output).
