8d424e039e Reduce rendering cost in long chats (#7052)
* perf(app): stop re-walking the timeline on every streamed delta

Every coalesced delta rebuilds the stream render model with the same
tail. The model re-sliced the tail at the history-window start on every
call, so the rendered tail was a fresh array per delta and every WeakMap
keyed on it (ordering, history split, turn timing, the layout history
cache, row revision) missed each time. Cache the slice by tail identity
and window start.

Turn timing then still walked the whole rendered tail per delta and
allocated a new assistant-timing Map, which the layout memo depends on.
Split the walk: the tail is walked once per tail identity and the head is
walked from the carried open turn per delta. The Map keeps its identity
while the head adds no completed turn.

Adds identity-contract tests and a vitest bench for the per-delta
pipeline. 200 deltas over a 2,000-item timeline, mean per run:
default mounted window 5.68ms -> 2.82ms, history fully revealed
16.95ms -> 1.81ms.

Fixes #4816

* perf(app): keep the stream view's per-delta work bounded by the head

The chat outline concatenated tail and head, reduced over the result in
the render body, and rebuilt jumpToPrompt on every delta even when the
outline was disabled, which is every native viewport. Memoize the tail's
contribution, scan only the head per delta, do nothing while disabled,
make jumpToPrompt a stable event so the rail's memo holds, and republish
the active prompt only when the index or reading position changes.

The view built a Set of every mounted id plus the live head per delta for
the outline's pending-jump check; key it on mounted history only and
treat live head rows as always mounted. Split plugin projection so a head
change does not re-project the tail, memoize the history-window boundary
lookup, and read the turn presentation's submission flag with some()
instead of allocating a filtered array.

Paseo mobile app

Paseo is an open source agentic development environment for desktop, mobile, web, and CLI. Open the desktop app and work: agents, editor, terminals, diffs, pull requests, and a browser in one window. Run many agents at once, each in its own worktree, on one machine or several. The mobile app is the full app, native on iOS and Android.

  • Parallel agents: Run many agents at once, each in its own worktree.
  • Built-in orchestration: Agents in Paseo can create worktrees, launch other agents, and talk to them, across providers.
  • Complete development workflow: Edit files, review diffs, open pull requests, and run terminals, in split panes you arrange how you want.
  • Self-hosted: Agents run on your machine with your full dev environment. Use your tools, your configs, and your skills.
  • Multi-provider: Claude Code, Codex, Copilot, OpenCode, Pi, Antigravity, and Muse Code through the same interface. Pick the right model for each job.
  • Voice control: Dictate tasks or talk through problems in voice mode. Hands-free when you need it.
  • Cross-device: iOS, Android, desktop, web, and CLI. Start work at your desk, check in from your phone, script it from the terminal.
  • Privacy-first: Paseo doesn't have any telemetry, tracking, or forced log-ins.

Run parallel tasks in Paseo: start agents in separate worktrees, review their diffs, run each app, and check it in the built-in browser.

Plugins

Plugins run on the daemon and show up in every client you connect, with the same UI on desktop, web, iOS, and Android. Write a plugin once and it is on your phone.

  • UI: screens, sidebar items, workspace panels, Command Center items, slash commands, composer pills, attachment sources, timeline items, themes.
  • Agent lifecycle: change configuration, environment, and MCP servers, answer permissions, follow up when a turn ends.
  • Providers: add a coding agent as a provider.

Install from the registry with paseo plugin add owner/slug, or from Git or a local directory.

Browse plugins · Plugin docs

Plugins run with access to your daemon machine and inside connected clients; install only code you trust.

Getting Started

Paseo runs a local server called the daemon that manages your coding agents. Clients like the desktop app, mobile app, web app, and CLI connect to it.

Prerequisites

You need at least one agent CLI installed and configured with your credentials:

Download it from paseo.sh/download or the GitHub releases page. Open the app and the daemon starts automatically. Nothing else to install.

To connect from your phone, open Settings → your host → Pair Device.

Server

For a server, a VM, or any machine without the desktop app. Install the CLI and start the daemon:

npm install -g @getpaseo/cli
paseo

Paseo starts, then asks whether to enable the end-to-end encrypted relay for device pairing. If you decline, connect directly over TCP, Tailscale, or another VPN. The desktop, mobile, and web apps connect to this daemon like any other host.

For full setup and configuration, see:

Docker

Run the Paseo daemon and self-hosted web UI in Docker:

docker run -d --name paseo \
  -p 6767:6767 \
  -e PASEO_PASSWORD=change-me \
  -v "$PWD/paseo-home:/home/paseo" \
  -v "$PWD:/workspace" \
  ghcr.io/getpaseo/paseo:latest

Open http://localhost:6767 after it starts. Extend the base image with the agent CLIs you use, then provide credentials through environment variables or the persistent /home/paseo volume. See the Docker documentation for full setup details.

CLI

Everything you can do in the app, you can do from the terminal.

paseo run --provider claude/opus-4.6 "implement user authentication"
paseo run --provider codex/gpt-5.5 --worktree feature-x "implement feature X"

paseo ls                           # list running agents
paseo attach abc123                # stream live output
paseo send abc123 "also add tests" # follow-up task

# run on a remote daemon; --cwd is a path on that host
paseo run --host workstation.local:6767 --cwd /workspace "run the full test suite"

See the full CLI reference for more.

TypeScript SDK

Build issue integrations, dashboards, and orchestration services with @getpaseo/client:

import { createPaseoClient } from "@getpaseo/client";

const client = createPaseoClient({ url: "ws://127.0.0.1:6767/ws" });
await client.connect();

const agent = await client.agents.create({
  config: { provider: "codex/gpt-5.5" },
  cwd: "/Users/me/dev/storefront",
  prompt: "Review the current diff and name the riskiest change.",
});

const result = await agent.waitForFinish();
console.log(result.lastMessage);

await client.close();

See the SDK quickstart, recipes, and API reference.

Skills

Skills teach your agent to use Paseo to orchestrate other agents.

npx skills add getpaseo/paseo

Then use them in any agent conversation:

  • /paseo-handoff — hand off work between agents. I use this to plan with Claude and then handoff to Codex to implement.
  • /paseo-advisor — spin up a single agent as an advisor for a second opinion, without delegating the work itself.
  • /paseo-committee — form a committee of two contrasting agents to step back, do root cause analysis, and produce a plan.

Development

Quick monorepo package map:

  • packages/server: Paseo daemon (agent process orchestration, WebSocket API, MCP server)
  • packages/app: Expo client (iOS, Android, web)
  • packages/cli: paseo CLI for daemon and agent workflows
  • packages/desktop: Electron desktop app
  • packages/relay: Relay transport and encryption used by the daemon and clients
  • packages/website: Marketing site and documentation (paseo.sh)

Common commands:

# run all local dev services
npm run dev

# run individual surfaces
npm run dev:server
npm run dev:app
npm run dev:desktop
npm run dev:website

# build the server stack
npm run build:server

# repo-wide checks
npm run typecheck

Support Paseo

Paseo is an independent project used by tens of thousands of developers daily, built by one person and funded by the people who use it. Support the work on GitHub Sponsors. Companies can sponsor Paseo monthly and have their logo shown at the top of this README and on the paseo.sh homepage and docs.
