# Pricing — Hal

Last updated: 2026-05-09

Hal is presented on this website as a free, open-source, terminal-first CLI for PRD-native coding loops with AI agents such as Codex, Claude Code, and Pi. This website does not describe a hosted Hal Cloud plan, paid tier, seat price, usage quota, SLA, or managed service today.

## Free open-source CLI

- Public listed price on this website: $0 for the Hal CLI described here

- Install command: brew tap j-yw/tap && brew install --cask hal
- Source repository: https://github.com/ReScienceLab/hal
- Website pricing page: https://hal.rocks/pricing/
- ReScience Lab product page: https://rescience.com/products/hal

## Included product areas

- Plan the work before the agent writes code: Turn product intent into stories, acceptance criteria, and reviewable state before an AI coding agent touches the repo.
- Fresh context for every implementation story: Keep long AI coding work from turning into one drifting chat by giving each story its own bounded context window.
- Bring your coding agent into the Hal loop: Use Codex, Claude Code, or Pi inside the same PRD-driven loop without rewriting your planning workflow.
- Inject project standards into each agent loop: Give each AI coding iteration the repo-specific commands, conventions, and review rules it needs to stay consistent.
- Preserve the state behind every coding loop: Preserve progress, reports, workflow files, and loop state so AI coding work can be paused, inspected, and resumed.
- A deterministic pipeline for AI coding work: Move through planning, conversion, validation, implementation, reporting, and archive behavior as one explicit coding loop.
- Hal vs direct agent prompting: Compare Hal's PRD-native coding loop with direct AI coding agent prompting for planning, validation, reviewability, and merge safety.

## External costs not included

- AI coding engine subscriptions, model/API usage, or IDE tooling
- Repository hosting, CI, preview deployments, production hosting, analytics, or monitoring
- Human code review, QA, security review, legal review, or release management

## Adoption caveats

- Hal structures coding loops; it does not remove developer review before merging.
- Hal does not guarantee code quality, tests passing, delivery speed, revenue, rankings, or product outcomes.
- Verify the current source repository, release notes, and install path before adopting Hal in production work.
