* perf(claude): scan transcripts incrementally The claude session scanner re-read the entire transcript JSONL on every scan, so the cost of each poll grew with the length of the conversation. Track a byte offset per file instead and parse only the bytes appended since the previous scan. A trailing partial line — a write still in progress — is held back until its newline arrives. A file that shrank resets the cursor to 0; the base scanner's uuid dedup absorbs the re-sent events. A read that fails returns no events and leaves the cursor where it was, so a transient error is retried on the next scan rather than skipping content. The codex scanner received this in #1031; this extends the same improvement to the claude scanner. readSessionLog is exported for tests, mirroring readTranscriptRange there. * fix(claude): forward a complete final record with no trailing newline The incremental reader consumed only through the last newline, so a final JSONL record flushed without its terminating newline — at shutdown or on import — was held back as if it were a partial write and never forwarded until a later append supplied the newline. The previous whole-file reader parsed such a record. Consume a trailing segment when it already parses as a complete JSON value, and keep holding back a genuinely partial line (which parses as incomplete).
HAPI
Run official Claude Code / Codex / Cursor Agent / Grok Build / OpenCode 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—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.
