Per-session notes/drafts workbench, the native twin of the web ScratchlistPanel + use-hub-scratchlist (tiann/hapi#893): - wire/ScratchlistApi.kt: entry/attachment/limits DTOs mirroring shared/src schemas, caps (200 entries / 10k chars), typed error codes (scratchlist_at_cap, _attachment_too_large, _attachment_in_use, ...). - HapiApi: entries CRUD (POST idempotent-on-entryId), limits GET, base64-JSON attachment upload, raw-bytes fetch over the cached image client, attachment delete. - SessionStore now surfaces scratchlistUpdatedAt patches as a scratchlistInvalidations SharedFlow (bare refetch trigger, sse.md). - ScratchlistStore: per-session entries StateFlow, refresh on open + on SSE signal (observed sessions only, 16 ms coalesced), optimistic create/update/delete with surgical rollback, friendly atCap state (local pre-check + hub 409), uploads-in-flight progress, cached limits with offline defaults. ScratchlistAttachmentGuard holds the pure pre-upload budget verdicts (fits / downscale-to-target / reject). - feature/scratchlist: chat/{id}/scratchlist route, entry cards (text preview, relative age, authed Coil thumbnails), edit sheet (text + attachment strip with photo picker, downscale-to-JPEG import, remove, delete), FAB new note, full-screen viewer (generated-image pattern). - Chat seams: top-bar notepad badge (entry count), composer overflow "Park draft to scratchlist" (clears only after the hub accepts), and per-entry "To composer" that inserts into the live ChatViewModel of the chat entry below the route. Tests: store CRUD optimistic/rollback + cap 409 + invalidation-signal refetch + upload progress/413 + attachment delete 409 (MockWebServer), guard verdicts, ChatViewModel park/insert/badge seams (fake store).
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
