v0.2.1 October 7, 2026 On GitHub ↗

A universal installer for macOS: one package for Apple silicon and Intel Macs that puts Splash in Applications.

New

  • Splash-0.2.1-macos-universal.pkg: one installer for every Mac running macOS 14 or later. The app inside runs natively on Apple silicon and Intel. It is signed with a Developer ID, notarized by Apple, and stapled, as is the installer itself.

v0.2.0 October 7, 2026 On GitHub ↗

Splash now runs on macOS, Windows and Linux, comes with a headless server you can use from a browser over SSH, and adds the views that keep several agents manageable: one queue for everything waiting on you, a review panel, a searchable session library and GitHub triage.

New

  • Needs attention: one persistent queue for pending permissions, failed connections and finished turns, across restarts.
  • Review: the latest response, failed tools, changed files and the branch's pull request, with feedback straight back to the agent.
  • Session library: search saved and archived transcripts across agents and open a result at the matching message.
  • Agent history: discover sessions from installed agents over ACP, preview them without sending a prompt, then add, refresh, fork or delete them.
  • GitHub: triage issues, pull requests, branches and Actions runs across repositories, and start a session or a PR-head worktree from any item.
  • splash-server: run Splash on another machine and use it in a browser through an SSH tunnel, with token login and reconnect recovery.
  • Additional workspace folders are kept on new, load, resume and fork requests.
  • A new app icon, drawn for every platform's sizes.

Requirements

Install and sign in to your agent CLI separately; Splash finds it on your PATH. Adapters launched through npx also need Node.js and npm. Git is required for worktrees and the GitHub CLI for the GitHub view. Model selection, usage reporting and conversation resume appear when the agent supports them.

See the README for setup and open an issue for bugs or compatibility problems.

v0.1.0 October 5, 2026 On GitHub ↗

The first public preview of Splash: a macOS workspace for coding agents using the Agent Client Protocol.

Included

  • Run agent sessions in a project folder or an isolated git worktree.
  • Follow streamed responses, tool calls, diffs, plans and permission requests.
  • Browse changed files and use an integrated terminal in each session.
  • Resume supported agent conversations after restarting Splash.
  • Configure agent launch arguments and keyboard shortcuts.
  • Protect uncommitted work with an explicit discard confirmation when archiving or deleting a worktree session.

Install

Download Splash-0.1.0-macos-arm64.zip, extract it, and move Splash.app into Applications. The app is signed with a Developer ID, notarized by Apple, and includes a stapled notarization ticket. A SHA-256 checksum accompanies the ZIP.

The binary requires an Apple silicon Mac running macOS 14 Sonoma or later. Install and authenticate your agent CLI separately. Adapters launched through npx also need Node.js and npm; git is required for worktrees.

Early-preview limits

Agent capabilities vary: model selection, usage reporting and conversation resume appear only when supported by the agent. The registry includes 19 agents; this does not mean every agent/version combination has been tested. Intel, Windows and Linux binaries are not included in this release.
