wisp vs T3 Code
T3 Code is a free control surface for agent harnesses, with phone apps in both stores. wisp sends tasks off and hands you a report every turn. Where each is better, from their own docs.

T3 Code is the better pick if you want a native app on your phone that drives agents on a computer you leave on. wisp is for handing work off: every turn ends in a report by default, a named crew keeps working on a schedule, Auto picks the harness, and wisp Cloud runs the agents with nothing to install.
Side by side
| T3 Code | wisp | |
|---|---|---|
| In its own words | An “agent harness control surface” | Launch agents in the background and read what they hand back |

| Desktop | Windows, macOS and Linux, and a web app | macOS, Windows, Linux. Builds aren’t signed yet |
| Phone | iOS and Android apps. “The phone is a remote”: your computer does the work and stays on | Any phone browser, a Home Screen web app on iPhone with wisp Cloud, and an Android prototype you build from the repo. No native iPhone app |
| Where agents run | Your desktop, a server or a VPS | wisp Cloud: sign in and the agents run on a server. Free during the preview |
| One prompt on several models | Yes: Shift-click models, each gets its own thread and worktree | Yes, Compare: a run per harness, side by side, keep the better one |
| Click an element, send it to the agent | Yes, in its desktop browser: picked elements and preview annotations land in the composer | Yes, Pick element in Preview: its HTML and key styles go in the reply box, without a screenshot |

Where wisp is different
- The report. By default every wisp turn ends with a one-screen report of what changed, with the diff and the tests. T3 Code has Visual replies: ask, and the agent answers with a page.
- The crew. Named agents with a role, a schedule, a notebook and skills check in and report when something changed. T3 Code has scheduled tasks; wisp’s crew keep a notebook from job to job.
- Auto. wisp picks the harness, model and thinking level per task from what worked before, and shows the pick before you send.
- A hosted wisp. T3 Code’s phone needs your computer on. wisp Cloud runs the agents on a server with every lid shut, and you sign in with nothing to install. It’s a preview on one small server.
Where T3 Code is better
- Phone apps. It has apps for iOS and Android. wisp has no native iPhone app, and its Android app is a prototype you build from the repo.
- Picking elements. Picked elements and preview annotations reach the agent with your note and a screenshot. wisp’s Pick element adds its HTML and key styles as text, without a screenshot.
- Voice. Dictate into the composer. wisp’s dictation is on Android only.
- Git hosts. GitHub, GitLab, Forgejo, Gitea, Bitbucket and Azure DevOps. wisp’s Ship it goes through the GitHub CLI.
- PR watching. It checks a PR every two minutes and wakes the agent when a check fails. wisp gets there with a CI failed trigger you set up.
- Community. Far larger than wisp’s, which is one owner and a crew.
Pick T3 Code if
- Your phone is where you want to drive agents, and a computer of yours is always on.
- You work on GitLab, Bitbucket or another host besides GitHub.
- You want to choose each model yourself and fan a prompt out across them.
Pick wisp if
- You want a report every turn by default, without asking for one.
- You want agents that keep their own memory and run on a schedule.
- You don’t have a computer that stays on, and want the agents hosted.
Questions
Is T3 Code free?
Yes. Its FAQ says there’s no way to pay for it, and that its relay has a machine limit that goes up with T3 Chat plans. wisp is free too, and both use your own agent plans.
Does T3 Code run agents in the cloud?
Its FAQ says agents run wherever T3 Code runs: your desktop, a server or a VPS, and the phone is a remote. wisp Cloud is a hosted wisp where the agents run on our server.
Can I run one prompt on several agents?
In both. T3 Code does it with Shift-click in the model picker; wisp does it with Compare.
Does wisp have a phone app?
An Android prototype you build from the repo, a Home Screen web app on iPhone with wisp Cloud, and any phone browser. There’s no native iPhone app.
