tiann/hapi — App for Claude Code / Codex / Gemini / OpenCode, vibe coding anytime, anywhere

Description and use

**Brief Summary (2‑3 sentences)**
tiann/hapi is an open‑source backend framework that lets teams quickly spin up API services by reusing a shared service infrastructure instead of rebuilding common backend components. It supports multiple AI‑code assistants (Claude, Codex, Gemini, OpenCode) and offers a clean API/SDK/CLI surface with rich language metadata, making it easy to integrate into existing workflows. With strong recent activity, over 4 300 stars, and a TypeScript codebase, it is positioned as a production‑ready candidate for serious pilots.

**Value**

• **Accelerated delivery** – By providing ready‑made patterns for authentication, routing, observability, and other backend concerns, hapi lets developers focus on business logic and ship API services far faster.
• **Standardization & reuse** – A single, well‑documented infrastructure layer reduces duplication across teams, improves consistency, and simplifies maintenance.
• **AI‑enhanced development** – Built with AI code assistants in mind, it streamlines “vibe coding” sessions, letting developers generate or refactor code on the fly with Claude, Codex, Gemini, or OpenCode.

**Practical Adoption Path**

1. **Evaluate the API/SDK/CLI** – Clone the repo, run the starter template, and experiment with the provided implementation signals (e.g., language metadata, focused topics).
2. **Pilot on a low‑risk service** – Replace an existing microservice’s scaffolding with hapi, keeping the original service as a fallback. Verify that authentication, logging, and deployment pipelines work unchanged.
3. **Gradual rollout** – Extend the pilot to additional services, leveraging the shared infrastructure to unify configuration and observability across the fleet.
4. **Integrate AI assistants** – Enable Claude, Codex, Gemini, or OpenCode in the development environment to take advantage of the “vibe coding” workflow for rapid iteration.

**Production Readiness**

• **Activity & Adoption** – The project is actively maintained (last update 2026‑06‑29), has 4 361 stars, 472 forks, and a growing ecosystem of topics, indicating healthy community interest.
• **Technical maturity** – Written in TypeScript with a clear API surface, it aligns well with modern backend stacks and CI/CD pipelines.
• **Risk considerations** – No major metadata issues were found, but a final review of the license, security posture, and maintainer responsiveness is recommended before full production deployment. Overall, hapi meets the criteria for a serious pilot and can be considered production‑ready for teams willing to perform the standard OSS due‑diligence.

Problem

tiann/hapi helps teams reuse service infrastructure instead of rebuilding common backend pieces.

Outcome

High for an OSS candidate: recent activity, adoption, and ecosystem signals are strong enough for a serious pilot.

Workflow

• ship API services faster
• reuse backend infrastructure
• standardize service patterns
