Promptuaria
Promptuaria is a Git-backed platform for publishing, versioning, forking, and reusing software specifications, particularly as coding agents increasingly build applications from specs. It links GitHub implementations to the exact immutable specification versions they were built from.
At a Glance
- Software developers and coding-agent users
- Open-source developers and project maintainers
- Technical communities sharing reusable application specifications
- Researchers and builders interested in reproducible spec-to-implementation workflows

Show HN: Promptuaria – GitHub for specs
Published earde-social v1, a detailed specification for open-source communities combining chat, searchable threads, and shared discussions across connected projects
Published the Launch Smoke Test v1 specification and its forked Northstar variant
Published terms of use and privacy notice describing Promptuaria as an early free service operated by Damiano Presa
Products & Services
A free platform for publishing software specifications, maintaining immutable Git-versioned releases, forking specs, and associating implementations with exact GitHub repositories and commits. It also supports GitHub sign-in, public profiles, stars, discussions/comments, downloads, and copying build prompts.
Market Position
Promptuaria positions itself as a 'GitHub for specs': unlike conventional code hosts, its primary artifact is an executable software specification rather than source code, with immutable published versions and explicit links from implementations to the spec version and commit. Conceptually it overlaps with GitHub/GitLab repository workflows and prompt/spec libraries, but focuses on agent-oriented software requirements and provenance.
Leadership
Founders
Damiano Presa
Promptuaria's operator and apparent solo creator; he publishes under the Hacker News/GitHub identity tolarianwiz/turbodami. The public launch post describes him as the person who built Promptuaria over a few days.
Executive Team
Damiano Presa
Operator
Identified by Promptuaria's terms and privacy notice as the person operating the service; he authored the public Hacker News launch post.
Founding Story
Damiano Presa said he was seeing more people share software specifications instead of code and expected this to become more common as coding agents improved at one-shot application development. He built Promptuaria as an early side project to make specs shareable and reusable in a manner analogous to code, with Git versioning, immutable published versions, forks, and traceable GitHub implementations.
Business Model
Revenue Model
Free of charge at launch; the terms describe Promptuaria as an early service offered free of charge.
Pricing Tiers
The service is offered free of charge; no paid plans are listed publicly.
