SplashCompareT3 Code

Splash and T3 Code, compared.

Splash and T3 Code both run several agents at once, each in a project folder or its own git worktree. T3 Code pairs a server that runs agents with desktop, web, iOS and Android apps, and uses each agent’s own interface. Splash is a desktop app, with an optional headless server you open in a browser, that speaks the Agent Client Protocol with every agent.

Side by side

SplashT3 Code
The basics
What it is Desktop app, plus a headless server you open in a browser16 Desktop, web, iOS and Android apps controlling a server that runs the agents; the server also runs alone as the t3 CLI45
Release status v0.2.1, early development17 Stable v0.0.45, released 2 October 2026, and nightly builds several times a day; the makers call it alpha and early-stage891011
License Open source (MIT)12 Open source (MIT), the T3 Connect relay included; the Terms also cover use of the hosted services131411
Price Free15 Free; no paid plans are listed, and the Terms say there is currently no subscription fee311
Platforms macOS 14+ (Apple silicon and Intel), Windows 11 x64, Ubuntu 24.04 x6416 macOS (Apple silicon, Intel), Windows 10 and 11 (x64, arm64), Linux x86_64 and arm64 (.deb, AppImage); iOS 18+ and Android178184
Built with Rust, with a Svelte 5 frontend in a webview, built on the Elyra framework19 TypeScript: an Electron desktop app, Expo and React Native mobile apps, and a Node.js server built on Effect10820
Agents
Agents Ships launch commands for 20 agents, including Claude Code, Codex, Copilot, Gemini, Goose, OpenCode2122 Stable: Codex, Claude Code, Cursor, Grok Build, OpenCode, Antigravity. Nightly adds Pi, Muse Code (beta) and ACP agents (Registry or local)42324252627
How it runs agents The protocol or interface Agent Client Protocol over stdio, natively or through a pinned adapter for the vendor’s CLI212 An adapter per agent: Claude Agent SDK, Codex app-server, an OpenCode server; Grok, Antigravity and (in stable) Cursor over ACP2829303132
Agent sign-in Who pays for the model You install and sign in to each agent’s CLI yourself; Splash runs it with that login22 Your existing agent logins and subscriptions; T3 resells no tokens, and each provider instance can hold its own API keys4323
Account required Splash has no accounts; splash-server asks for a token it keeps in its data folder336 Not for local use or direct connections; T3 Connect and mobile push notifications need a T3 account341135
Permission requests When an agent asks before it acts Yes: Shown in the transcript and answered with the 1–9 keys; pending ones wait in Needs attention36 Yes: Answered in the conversation; four modes per thread, from Supervised to Full access (the initial default for new threads). Options vary by provider37
MCP servers Partly: Read-only list of MCP servers from Claude Code, Codex, Pi, Pool and Glue config files3638 Yes: Agents get T3’s own MCP tools and load their own servers; nightly builds let outside agents sign in to T3’s MCP server2839404142
Working in parallel
Isolation per session Yes: The project folder, or a git worktree on its own branch per session36 Yes: Per thread: the current checkout or a new worktree on its own branch. Shift-clicking several models starts one worktree thread each4344
Setup scripts and dev servers No: A worktree is a plain git checkout; Splash runs no setup scripts or dev servers3645 Yes: Scripts in a checked-in t3.json run in a T3 terminal, optionally on worktree creation, and can open a preview URL on desktop44
Built-in browser For previewing dev servers No: No built-in browser; the workbench holds git changes, a file tree, diff and file tabs, and a terminal36 Yes: An in-app browser preview on desktop; nightly builds run it on the server, where you and agents share tabs from any device444647
Terminal Yes: A terminal in the session folder36 Yes: Built-in terminals on desktop, web and mobile, run by the server and keeping up to 5,000 lines of scrollback across reconnects4818
What needs you Yes: One queue for permission requests, connection failures and finished turns, kept across restarts3649 Partly: Sidebar sections for pinned, active, snoozed and settled threads; a beta option lifts threads that finish, fail or need you43
Review and shipping
Review changes Yes: Latest response, failed tools and every changed file as a diff, with a box to send feedback36 Yes: Inline diffs to check before pushing; diff comments go to the agent as chips; threads can rewind to an earlier message if the provider supports it340
Create pull requests No: Shows the PR for a session’s branch and starts worktrees from PR heads; does not create PRs3650 Yes: Commits, pushes and opens PRs from a thread with generated messages and descriptions; drafts, stacks, amends and auto-merge393
GitHub And other Git hosts Yes: Issues, pull requests and Actions runs across repositories, through the gh CLI3650 Yes: GitHub through the gh CLI, plus GitLab, Forgejo, Gitea, Bitbucket and Azure DevOps; a page to review, check out and merge PRs3951
Issue trackers Partly: GitHub (github.com), through the gh CLI; no Linear or Jira3650 No: None documented; the Git host integrations cover repositories and pull requests, not issues39
Where it runs
Mobile app No: No mobile app; builds cover macOS, Windows, Ubuntu and a headless server16 Yes: iOS 18+ and Android companion apps for your own machines, with push alerts via T3 Connect; nightly builds need the TestFlight or Play beta app1843523
Remote access Yes: splash-server runs on the machine with your code; you use it in a browser over an SSH tunnel. Single user.6 Yes: T3 Connect relay (with sign-in), direct LAN or Tailscale pairing, SSH hosts added from the desktop app, and the hosted web app46
Cloud execution No: Agents run as child processes on your computer, or on your own server with splash-server16 No: No hosted execution; agents run on machines you control, and an optional load balancer picks one for new threads465
History and search
Existing agent history Conversations started outside the app Yes: Browse, preview and import conversations agents list over ACP, including ones started outside Splash3649 Partly: First-run setup offers to import Claude Code and Codex conversations active in the last 30 days, without tool activity; nightly also imports from ACP agents that support it522526
Search transcripts Yes: Search titles, folders and saved transcript text, archived sessions included36 Yes: Cmd/Ctrl+K searches your messages and agents’ final replies across connected machines, on web and desktop43

Where they differ

How agents connect

T3 Code uses each agent’s own interface: the Claude Agent SDK, Codex’s app-server protocol, an OpenCode server, and ACP for Grok and Antigravity. Stable builds run Cursor over ACP too; nightly builds move it to Cursor’s SDK and add ACP Registry agents. Splash speaks the Agent Client Protocol with every agent, natively or through a pinned adapter.2829303132532526212

Clients and servers

T3 Code splits into a server, which runs agents, terminals and Git, and desktop, web, iOS and Android clients. The desktop app includes its own server, the t3 CLI runs one alone, and T3 Connect, direct LAN or Tailscale pairing, or SSH links devices. Splash is a desktop app; splash-server runs it on another machine, used in a browser through your own SSH tunnel.544616

Stable and nightly builds

T3 Code ships stable releases (v0.0.45, 2 October 2026) and several nightly builds a day. Nightly builds run a new orchestrator, merged about an hour after v0.0.45 shipped, and add the ACP Registry, Pi, Muse Code, PR watching, and scheduled and webhook tasks; the store mobile apps can’t connect to them. The docs on its main branch already describe these features. Splash tags a release when a new version on main passes CI.89262754552325395616

Accounts and cost

Both are free and MIT-licensed, and both run agents with your own agent logins. T3 Code needs no account for local or direct connections; its T3 Connect relay and mobile push notifications need a T3 account. Splash has no accounts; splash-server asks for a token it keeps in its data folder.131143435121522336

Around the session

T3 Code adds tooling around the agents’ work: t3.json setup scripts, an in-app browser, a panel streaming an iOS Simulator or Android Emulator, a Usage page, and pull requests across six Git hosts. Splash adds tooling around conversations: a Needs attention queue, a review screen, transcript search, importing sessions agents list over ACP, and a GitHub view with Actions runs.44575839364950

Which one fits

Splash may suit you if

  • You want no accounts at all, on the desktop or as a server you reach over SSH.
  • You use agents such as Gemini, Copilot or Goose, which Splash ships ACP launch commands for.
  • You want permission requests and finished turns in one queue, and search over full saved transcripts, tool output included.
  • You want to import conversations from any agent that lists them over ACP, and triage GitHub issues and Actions runs.

T3 Code may suit you if

  • You want to follow and steer your agents from an iPhone, iPad or Android phone.
  • You want to commit, push and open pull requests from a thread, then review and merge them on GitHub, GitLab, Bitbucket and other hosts.
  • You want setup scripts in a checked-in t3.json and an in-app browser for previews.
  • You want to reach your machines through T3 Connect, Tailscale or SSH, and spread new threads across them.
