***plain SF #001: Beyond Vibe Coding
The first ***plain SF Meetup
Join us for the first ***plain SF Meetup — a small, handpicked gathering of ~20 developers and engineers who want to go beyond the current AI coding hype and explore what a spec-first development workflow actually looks like in practice.
Hosted at the European Startup Embassy in San Francisco. A home base for technical founders and builders operating at the edge of what's next.
Thursday, April 16 · 6:30 PM European Startup Embassy · San Francisco
Expect a tight technical session, honest conversation, and no fluff. Spots are limited and curated. If you're here, you were invited for a reason.
----------------------------------
Vibe-coding gets you started. It rarely gets you finished.
AI code generation is powerful but prompt-driven workflows are fragile, non-deterministic, and leave no authoritative record of why the software does what it does. When something breaks, there's no spec to return to. Just a pile of generated code and a vague memory of what you asked for.
*codeplain is building a different answer: spec-driven development.
The idea is straightforward but radical. Natural language specifications become the single source of truth for your software. Not documentation written after the fact. Not a prompt you typed once and forgot. A living, structured spec that drives code generation, testing, and validation, every time.
At the core of this is ***plain, an open-source specification language that combines the expressiveness of natural language with the precision and repeatability of code. Write what the software should do. *codeplain takes it from there.
