AI prompts as infrastructure, not strings in code
Write prompt templates with Handlebars syntax. Define typed variables. Generate type-safe SDK functions for Go, TypeScript, and more. Update prompts without redeploying your app.
Write prompts with real templating
Handlebars syntax with conditionals, loops, and context switching. Variables are detected automatically and assigned types for code generation. No more string concatenation in your codebase.
- Handlebars syntax — #if, #each, #with, #unless
- Auto-detected variables with type assignment
- AI-powered prompt generator to get started fast
Type-safe functions, not string building
PromptHub generates SDK functions for Go, TypeScript, and Python. Each function takes typed arguments matching your template variables — compile-time safety for your AI prompts.
- Go structs, TypeScript interfaces, Python dataclasses
- Compile-time type checking — catch errors before runtime
- Import and call — no template parsing in your code
Update prompts without deploying
Use the generated SDK for compile-time safety, or fetch prompts via REST API for runtime flexibility. Change a prompt in the dashboard and every API call returns the new version immediately.
- REST API with API key authentication
- Update prompts without code changes or deploys
- A/B test prompt variations without feature flags

From prompt to production code
Version history
Every edit is versioned. Compare any two versions side by side. Roll back with one click. Know exactly what changed and when.
Team collaboration
Shared prompt workspace for your team. Everyone sees the same prompts, same versions, same types. No more prompts hidden in someone's branch.
Why this needs to exist
AI prompts today are strings buried in code. No versioning, no types, no collaboration. Every team reinvents the same bad patterns.
Prompts in code are fragile
String concatenation, f-strings, template literals. One wrong variable and the AI gets garbage input. No compiler catches it. No tests cover it.
No single source of truth
Prompts scattered across repos, Notion docs, Slack messages. Product wants to tweak copy, but they need a developer to deploy it.
No iteration workflow
Change a prompt and hope for the best. No version history, no diff, no rollback. Was the last version better? Nobody knows.
