Everything on pre.dev — spec generation, build sprints, browser agent tasks — draws from one credit balance. Every plan refills that balance monthly.
pre.dev/pricing is the source of truth for current prices, credit amounts, and plan features. The numbers below reflect the pricing page at the time of writing.

​
Plans

A few feature notes, per the pricing page:
  • Pro Mode — pin the strongest model to every phase of a build — is included from the Premium plan.
  • Deep Spec — the granular, subtask-level specification — is included from the Pro plan. Fast Spec is available on every plan.
  • Core building blocks — architecture planning, autonomous coding and verification agents, automatic deployment and preview, GitHub automation, and data-source connections — are on every plan, including Free.

​
What credits pay for

Spec generation

Fast Spec: ~5–10 credits, ~1 minute. Deep Spec: ~10–50 credits, ~3–5 minutes. Cost scales with project complexity.

Build work

Sprints consume credits as the agent researches, codes, and verifies. Higher effort levels do more model work and cost more.

Browser agent tasks

1 credit = $0.10, billed per task with a 0.1-credit floor. Failed tasks are free.
Failed browser agent tasks aren’t billed, but you need at least the 0.1-credit floor available for a task to start.

​
Check your balance

Three ways, depending on where you are:

In the workspace

Type /balance in the chat composer for your remaining credits.

On the web

pre.dev/projects/key shows your balance alongside your API key.

From the API

GET /credits-balance returns your remaining credits programmatically.

​
Per-project cost analytics

The workspace tracks what each project has spent, so you can see where credits actually go — which sprints, which phases, which features. Use it to decide where auto effort is fine and where a cheaper low-effort pass would do.

​
What happens when credits run out mid-build

Running out of credits during a sprint doesn’t lose your work:
1

The build pauses safely

The agent stops at a clean point. Nothing is discarded — the code, the plan, and the sprint’s progress are all preserved.
2

You get an email

It includes the build’s current progress, screenshots of the app so far, and a link to the live preview — so you can judge how far it got without opening the workspace.
3

Top up and resume

Add credits or upgrade at pre.dev/pricing, then resume the build. It picks up where it paused.

FAQ

See pre.dev/pricing for the current policy on credit refills and rollover.
Fast Spec (~5–10 credits) is the default and right for most projects. Deep Spec (~10–50 credits) adds granular subtasks and is worth it for complex, production-bound builds. See Fast vs Deep.
At 1 credit = $0.10 with a 0.1-credit floor per task, a credit covers up to ~10 simple tasks — and failed tasks cost nothing.
The Enterprise plan has unlimited credits, the Architect API + MCP, and a dedicated solutions engineer — contact us via pricing.
