Port of the tested Android NEW SESSION reference (B-M3d) to iOS: - HapiProtocol: NewSessionCatalogs (static claude models/efforts + codex reasoning-effort fallback, exact Android data) in Catalog/; CodexModelSummary + CodexModelsResponse wire types (shared/src/apiTypes.ts). - HapiClient: machineCodexModels endpoint (GET /api/machines/:id/codex-models, rpc_target_missing surfaces as APIError); NewSession/NewSessionForm.swift — typed Codable draft (tolerant decode) + NewSessionLogic: exact spawn body per SpawnSessionRequestSchema (yolo incl. false for non-grok/non-codex-family, permissionMode incl. 'default' for grok+codex-family, sessionType always, trimmed-or-absent worktreeName, serviceTier only while fast tier visible, collaborationMode only when plan, model only claude/codex), parent-path derivation, suggestion filtering, recent-path LRU(8), worktree-name validation, codex catalog helpers, draft sanitization. - App: Features/NewSession (NewSessionModel @Observable orchestration — machine preselect last-used, 250 ms debounced list-directory autocomplete with per-parent cache, exists probe with worktree-blocking / simple two-tap-create, codex catalog fetch + selection reconcile, UserDefaults draft/prefs per hub; NewSessionView Form UI with per-flavor option matrix); session-list "+" toolbar button on HomeView presents the sheet, success dismisses and pushes the chat. - Tests: spawn-body exactness (4 configs, canonical JSON), parent query, suggestions, LRU, worktree validation, fast-tier detection, reasoning-effort normalization, draft sanitize + tolerant decode; codex-models endpoint request/error construction.
HAPI
Run official Claude Code / Codex / Cursor Agent / Grok Build / OpenCode / Kimi / Copilot / Antigravity / Pi sessions locally and control them remotely through a Web / PWA / Telegram Mini App.
Why HAPI? HAPI is a local-first alternative to Happy. See Why Not Happy? for the key differences.
Features
- Seamless Handoff - Work locally, switch to remote when needed, switch back anytime. No context loss, no session restart.
- Native First - HAPI wraps your AI agent instead of replacing it. Same terminal, same experience, same muscle memory.
- AFK Without Stopping - Step away from your desk? Approve AI requests from your phone with one tap.
- Your AI, Your Choice - Claude Code, Codex, Cursor Agent, Grok Build, OpenCode, Kimi, Copilot, Antigravity, Pi—different agents, one unified workflow.
- Terminal Anywhere - Run commands from your phone or browser, directly connected to the working machine.
- Voice Control - Talk to your AI agent hands-free using the built-in voice assistant.
- Workspace Browser - Opt-in via one or more
hapi runner start --workspace-root <path>flags: browse scoped file trees from the web and start sessions in allowed subdirectories.

Getting Started
npx @twsxtd/hapi hub --relay # start hub with E2E encrypted relay
npx @twsxtd/hapi # run claude code
hapi server remains supported as an alias.
The terminal will display a URL and QR code. Scan the QR code with your phone or open the URL to access.
The relay uses WireGuard + TLS for end-to-end encryption. Your data is encrypted from your device to your machine.
For self-hosted options (Cloudflare Tunnel, Tailscale), see Installation
Docs
Native apps (iOS / Android)
Fully native SwiftUI and Kotlin Compose clients are in development under ios/ and android/. They pair with your hub by scanning the same terminal QR code as the web app, and follow the same protocol — see the client contract docs.
Build from source
bun install
bun run build:single-exe
