Plans & Limits
The limits enforced on each plan are listed below. Every paid tier has finite, predictable caps: Pro is 5x Starter and Enterprise is 20x Starter on most resources.
This table is generated from the same table the product enforces, so it can never drift from what you actually get.
| Free | Starter | Pro | Enterprise | |
|---|---|---|---|---|
| Price | $0/mo | $9.99/mo | $29.99/mo | $99/first user |
| Additional seats | — | — | $20/seat (up to 50) | Degressive pricing |
Free is a real plan tier, not a trial. It runs on your own machine (BYOM) using your own Claude key (BYOK) — there’s no platform AI or compute allowance and no cloud/cloud-worker DevBoxes. You do get one schedule (running at most every 6 hours) to taste automation. It’s the simplest way to self-host ClusterCode; upgrade to Starter+ for platform AI, more (and more frequent) schedules, and managed compute.

5× / 20× mark limits where Pro is exactly 5× Starter and Enterprise 20×.
A few notes:
- Cloud worker DevBoxes are managed cloud compute, so unlike self-hosted DevBoxes (which run on your own hardware) the cap reflects capacity we fund. Free has none — it’s BYOM-only — and the cap scales with your plan. During a free trial it is tighter still: see Trial limits below.
- Custom images is a use-cap: on a capped plan only the newest N managed images stay launchable (Free keeps the newest 3); older ones lock until you upgrade or remove some.
- Concurrent live sessions is the total of terminal + display sessions across all your DevBoxes (not a per-DevBox limit).
- Parallel subagents per run is how many helper agents a single run may spawn; it scales by plan (see the table above).
- Display idle timeout auto-closes an idle VNC display to free a live-session slot — it scales by plan (see the table above).
- Projects group your DevBoxes, runs, and schedules and carry per-project environment variables. The cap counts active projects only — archived projects are inert and don’t consume a slot, so you can keep history without spending against the limit.
- Active prototypes (Beta) is a per-user cap on how many prototype races can be in flight (contenders still working or queued) at once. A finished prototype frees its slot immediately — its preview DevBoxes staying alive doesn’t count against this cap (container compute is governed by the container limits above).
- Contenders per prototype (Beta) is how many engine+model pairs a single prototype may race at once. It’s checked when you create the prototype. Concurrency across those contenders is still governed by Concurrent runs above — extra contenders queue and start automatically as run slots free (on Free, they run one at a time).
Trial limits
Section titled “Trial limits”A free trial on a paid plan gets that plan’s features, with two limits held tighter while the trial is unvetted:
| During a short trial | After it converts | |
|---|---|---|
| Cloud worker DevBoxes | 1 at a time, per user | your plan’s cap (see the table above) |
| Cloud worker specs | Linux Small and Windows Small | every spec, up to Large |
Everything else — self-hosted DevBoxes, schedules, runs, AI allowance, included compute — is exactly the plan you’re trialling.
Both trial limits are per user, matching how cloud worker DevBoxes are counted on every plan. A trial that invites teammates therefore gets one cloud worker DevBox each, not one for the whole workspace.
Because the smallest specs are also the cheapest ($0.06/hr for Linux Small), your included trial compute stretches much further: roughly 100 hours rather than the ~25 you’d get on Linux Large. You can still launch a real Windows DevBox to evaluate it.
These limits do not apply if you:
- add a payment method — your subscription simply starts with a free period, so you get the full plan immediately, and your remaining trial credit is spent first; or
- have a trial we extended for you (an evaluation or a proof of concept).
If you need more headroom during an evaluation, get in touch — we can extend the trial rather than asking you to pay early.
AI & Compute Allowances
Section titled “AI & Compute Allowances”| Resource | Free | Starter | Pro | Enterprise |
|---|---|---|---|---|
| Platform AI allowance | None | $2/mo | $6/mo | $10/mo |
| Included compute | None | $2/mo | $6/mo | $10/mo |
5× / 20× mark limits where Pro is exactly 5× Starter and Enterprise 20×.
On Enterprise both allowances are per user. Pay-as-you-go wallet top-ups are available on every paid tier; BYOK is required on Free and optional elsewhere.
- Platform AI allowance and Included compute are separate monthly pools (LLM spend vs. container runtime), both denominated in USD.
- On Free there is no platform AI pool, so runs and Nucleus work only through your own key (BYOK) configured under Settings → Secrets. On paid tiers BYOK is optional — use the included platform allowance or your own key.
- Once an allowance is spent, paid tiers can keep going via the pay-as-you-go wallet (top-ups); Free cannot.
