# Versera

> Versera is prompt version control for LLM applications. Developers store prompts in a versioned API, resolve them at runtime with variable injection, and rollback instantly when something breaks — no redeploy required.

Versera gives developers building on Claude, GPT, Gemini, and other large language models Git-style versioning for their prompts. Free tier includes 1,000 credits on signup. Works with any LLM — the resolve endpoint returns a rendered string that can be passed to any inference API.
