Continuum vs T3 Code

The closest match in the category: vendor-neutral agent workbenches, split by source ownership versus a packaged cross-device operating loop.

T3 Code is the open-source control plane for coding agents from T3 Tools Inc, part of the t3.gg and Theo ecosystem. It brings Claude Code, Codex, OpenCode, Cursor, and Grok into one workbench under the subscriptions you already pay for, lets you switch models mid-conversation, gives every thread its own git branch, and can create a pull request in one click with a generated title. Its MIT license, 19k+ GitHub stars, self-hostable control plane, and apps for macOS, Windows, Linux, iOS, and Android make the ownership case unusually strong for a product whose first backlinks appeared in February 2026. Continuum is the other vendor-neutral multi-agent workbench, but it makes a different trade: packaged polish around the same live session as it moves between Mac, iPhone, web, and CLI, with plan-approval gates, first-class diff and PR review, live quota gauges, and a per-repo cost ledger. T3 Code wins when source ownership, Linux, Android, or a fork are non-negotiable. Continuum wins when the review and operating loop has to follow the run without being assembled by the operator.

Choose Continuum when

Pick Continuum when the same live session must follow you across Mac, iPhone, web, and CLI, with plan approval, diff review, PR merge, quota gauges, and repo-level cost already integrated, or when a team needs an organization at all: one bill by live member count, seats and roles, model policy by team and person, and weekly caps that refuse a request instead of emailing about it.

Choose T3 Code when

Pick T3 Code when MIT source, full forkability, self-hosting, a shipped Linux desktop, Android, or its branch-per-thread and one-click PR loop matters more than a packaged cross-device review and instrumentation layer.

Owned control plane vs continuous session

In Continuum

One live run through approval and merge

09:10

Start a Codex worktree session on the Mac. The conversation, branch, plan, diff, and PR state share one session id.

11:35

The read-only plan finishes during standup. Approve it from iPhone; the same host and thread move into the write-capable run.

15:15

Open the session on web, review the live diff hunk by hunk, revert one change, create the PR, and watch its checks.

17:20

Merge from the PR pane. Before the next run, check the provider quota gauge and the day's spend for this repo in Usage analytics.

In T3 Code

Own the workbench and move fast across platforms

09:10

Run T3 Code on Linux and connect the Claude Code, Codex, OpenCode, Cursor, or Grok subscription you already use.

11:35

Open a thread for the ticket. T3 Code gives the conversation its own git branch so the work stays separate.

15:15

Switch models in the middle of the conversation when a different agent is the better fit, without throwing away the thread.

17:20

Create the PR in one click with an auto-generated title. If the control plane needs to work differently tomorrow, fork the MIT-licensed source or self-host your own build.

02

Monday path

Monday with both vendor-neutral workbenches

Install, connect, first session - steps you can run the same day.

01

List the agent subscriptions you already have: Claude Code, Codex, OpenCode, Cursor, or Grok. Both products are built around bringing those relationships with you.

02

Install T3 Code on the desktop platform you want, or self-host the MIT-licensed control plane if ownership is the point of the evaluation.

03

Start one T3 Code thread for a bounded ticket. Confirm that it receives its own git branch, then switch models mid-conversation to test the handoff you will actually use.

04

Use the one-click PR action and inspect the generated title before the branch leaves your machine.

05

Open the same ticket in a Continuum worktree session and put the agent in Plan mode before writes begin.

06

Approve the plan from iPhone or web, then return to Mac or CLI without starting a second conversation.

07

Review the live diff, stage or revert the hunks you want, create the PR, watch checks, and merge from the session.

08

At the end of the day, compare the provider's live quota window with Continuum's per-repo cost ledger. Keep T3 Code for source ownership; keep Continuum for the integrated operating loop.

How Continuum keeps one run intact

How Continuum keeps the session and review loop together

  • A managed Code session binds one conversation to one real git worktree and branch, with plan, diff, PR, terminal, files, and artifacts as panes on the same run.
  • Mac, iPhone, web, and the continuum CLI are clients on the same wire, so an approval or interrupt acts on the live session instead of creating a mobile copy.
  • Plan mode stays read-only and approval-gated. Approval ends planning and respawns the same session with the provider's write permission, carrying the accepted plan forward.
  • The Diff pane reads the repository index directly and supports per-hunk stage, revert, and commit before a PR leaves the worktree.
  • The PR pane creates, reviews, watches checks, and merges through the GitHub CLI on the host, without detaching the result from the conversation that produced it.
  • Provider quota readings are polled live; local agent logs are priced into spend and tokens by repo, provider, model, and day.
  • Claude Code, Codex, Cursor, Grok, and peer providers stay under their own logins and subscriptions rather than a Continuum-specific model account.

Where the products actually diverge

01 · Ownership

T3 Code gives you the source. Continuum gives you the finished operating loop.

T3 Code is MIT licensed, fully forkable, and self-hostable. That is a categorical win when your team must inspect, change, or own the control plane. Continuum is a packaged product: its trade is less control over the workbench itself for a polished session, review, mobile, quota, and analytics contract that arrives integrated.

02 · Session model

A platform list is not the same thing as one live session.

T3 Code reaches macOS, Windows, Linux, iOS, and Android. Continuum's specific promise is continuity: Mac, iPhone, web, and CLI are doors into the same live thread and branch. Approve on the phone, watch the transcript in the browser, and return to the Mac without a restart or fork. The source claim is documented in sessions across every screen.

03 · Platforms

T3 Code wins Linux and Android without an asterisk.

T3 Code lists desktop apps for macOS, Windows, and Linux plus iOS and Android apps. Continuum's Mac client is stable and its Windows/Linux desktop remains beta; its deepest mobile control is on iPhone and Watch. If released Linux desktop support or Android is the gate, choose T3 Code plainly.

04 · Review and instruments

Continuum treats supervision as part of the session.

Continuum keeps Plan mode read-only until approval, projects the same plan card to Mac, iPhone, and Watch, then keeps live diff, per-hunk stage or revert, PR checks, and merge in the workbench. Live provider quota gauges and cost by repo sit beside that loop. T3 Code's verified fast path is different and genuinely useful: branch per thread, model switching mid-conversation, and a one-click PR with an auto-generated title.

05 · Maturity

Young does not mean small, but it does mean young.

T3 Code's first backlinks appeared in February 2026 and it already has 19k+ GitHub stars. That is meaningful open-source momentum, not a reason to dismiss it. It also means buyers should evaluate the repository and self-hosting path as a young product, while Continuum's pitch is the integrated polish of its session, review, quota, and cost surfaces.

Coexistence

Stack recipe

How people run both.

Stack recipe: use T3 Code where owning and changing the control plane is the requirement, especially on Linux or Android. Use Continuum for runs that need one live session across Mac, iPhone, web, and CLI, with plan gates, diff and PR review, quota truth, and cost by repo. Both bring their own agent subscriptions, so the decision can be made per project instead of as a permanent vendor bet.

Pick the tradeoff you want

Continuum

Choose Continuum when the session must travel

  • Need the same live session to follow you across Mac, iPhone, web, and CLI.
  • Want a read-only planning process with an explicit approval gate before writes begin.
  • Review live diffs hunk by hunk, then create, check, approve, and merge the PR from the session.
  • Schedule work against live provider quota windows instead of discovering the ceiling after a run stops.
  • Attribute tokens and API-equivalent cost by repo, provider, model, and day.
  • Prefer a packaged, polished workbench over maintaining or forking the control plane yourself.
  • Need one organization bill, seat provisioning, and three roles instead of every engineer expensing their own subscription.
  • Need weekly spend caps that stop a hosted request at the ceiling, with member requests an admin approves in one click.
  • Need model policy that resolves at organization, team, and member scope, where a lower scope can narrow access but never reopen what a higher scope denied.
  • Need offboarding that blocks provider access, revokes devices and tokens, and destroys the content key in one step rather than laptop by laptop.
  • Need a vendor you can pay: a support relationship, an Enterprise tier, and a counterparty for a security review.
T3 Code

Choose T3 Code when the control plane must be yours

  • Require an MIT-licensed control plane your team can inspect, fork, and change.
  • Want to self-host the full workbench, not only run agents on your own execution host.
  • Need a released Linux desktop instead of a beta client.
  • Need Android as part of the core cross-platform lineup.
  • Prefer branch-per-thread isolation and one-click PR creation with generated titles.
  • Want to build on a young open-source project that already has 19k+ GitHub stars.

What you pay and operate

Continuum

App + your labs

$0 for the app on Mac, web, iPhone, and Watch. Bring the Claude, ChatGPT, Cursor, Grok, or other provider subscriptions you already pay for, and Continuum takes no cut of those sessions. Optional hosted inference is a separate Plus, Max, or Ultra plan.

T3 Code

Their bill

T3 Code is MIT-licensed software you can fork and self-host. Bring your own Claude Code, Codex, OpenCode, Cursor, or Grok subscriptions. This comparison does not invent a separate T3 Code seat price that was not in the verified facts.

How to compare

Total cost of work

Both products leave provider billing with the providers. The economic trade is operational: own and maintain a forkable control plane with T3 Code, or use Continuum's packaged cross-device session, review, quota, and cost layer. For one person the trade is small, because T3 Code costs nothing. For a team it changes shape: T3 Code has no organization bill, so every engineer expenses their own subscription and finance reconciles by hand, while Continuum organizations are one subscription billed by live member count, with seats set at the Plus, Max, or Ultra tier and overage prepaid at cost with no markup. The honest limit on our side is identity: Continuum has no SAML, OIDC, or SCIM today, so a review that gates on SSO fails us as well.

T3 Code plans checked 3 August 2026 against their pricing page. Vendors reprice often - if you spot a stale figure, tell us and we will fix it. Continuum never marks up a session it runs under your own login.

Questions

Continuum vs T3 Code.

Deep dives: docs, providers, sessions.

T3 Code is the open-source control plane for coding agents from T3 Tools Inc in the t3.gg and Theo ecosystem. It puts Claude Code, Codex, OpenCode, Cursor, and Grok behind one workbench while you keep the subscriptions for those products.

Yes. T3 Code is MIT licensed, fully forkable, and self-hostable. Its repository has 19k+ GitHub stars. That source ownership is a real advantage over Continuum when changing or operating the workbench itself is a requirement.

The verified list is Claude Code, Codex, OpenCode, Cursor, and Grok. T3 Code is vendor-neutral and uses the subscriptions you already have for those agent products.

Yes. Multi-model switching mid-conversation is part of the T3 Code workflow, so a thread can move to a different model without being discarded.

Each T3 Code thread gets its own git branch. When the work is ready, T3 Code can create a pull request in one click and generate its title automatically.

Yes. T3 Code lists desktop apps for macOS, Windows, and Linux, plus mobile apps for iOS and Android. Linux and Android are two of its clearest advantages in this comparison.

Both are vendor-neutral multi-agent workbenches. T3 Code centers open source, self-hosting, forkability, and broad platform reach. Continuum centers one live session across Mac, iPhone, web, and CLI, with plan-approval gates, diff and PR review, live quota gauges, and cost history by repo.

Yes. Continuum's PR pane creates a pull request, shows checks and review state, supports approval, and merges through the GitHub CLI on the host. The Diff pane before it supports per-hunk stage, revert, and commit.

Its first backlinks appeared in February 2026, so it is a young product. Its 19k+ GitHub stars show unusually fast open-source interest; evaluate both the momentum and the shorter operating history on their merits.

No. T3 Code has no paid tier at all, so there is no organization bill, no seat to assign or reclaim, no admin console, and no role separation. Individuals on a team can all use it today, each under their own provider subscriptions. See T3 Code for teams for the full gap list.

None of the three. There is no SAML, OIDC, or SCIM, no org-scoped audit export, and no spend cap, because T3 Code never proxies a provider token and so never sees the billing relationship that a cap or a cost report would need. Thread history stays on the machine that ran it.

One subscription billed by live member count, three roles with delegated limits, model policy at organization, team, and member scope, weekly caps where a hosted request past the ceiling returns a 429 rather than an alert, member requests an admin approves in one click, one spend ledger across the gateway and your own keys, and offboarding that blocks provider access, revokes devices and tokens, and destroys the content key together. Every control and its limits are listed on the organizations page.

No, not today, and it is the one procurement row where T3 Code's absence and ours look similar. Sign-in and invitations run on WorkOS AuthKit with Google and Apple login, and there is no screen for federating your own identity provider or syncing a directory. If SSO is a hard gate in your review, neither product clears it. See the enterprise alternative comparison for products that do.

Yes on hosted, no on direct. Hosted traffic proxies through the gateway on purpose, because a pre-flight policy and budget check is the only thing that makes a cap enforceable. Direct and bring-your-own-key sessions run laptop to provider and send usage only, which preserves T3 Code's confidentiality property at the price of a weaker control.

Choose T3 Code for MIT source, self-hosting, forkability, Linux, or Android, and for any team small enough that it has no organization problem to solve. Choose Continuum when a single live session across screens, gated planning, deep diff and PR review, quota gauges, and a per-repo cost ledger matter more than owning the workbench source, or when a team needs one bill, enforced caps, model policy, and an offboarding path that does not run laptop by laptop.
