Free to author and inspect. Priced for what you run.

You can author `.swirls` files locally and deploy them to Swirls Cloud for free to inspect the compiled project. To run workflows and talk to agents, Developer is the production tier for a single user, and it starts with a 7-day free trial. If you are an engineering team that needs SSO, role-based access, longer audit retention, and business-hours support, Team is for you. Enterprise is for regulated deployments that need platform-managed provider keys, BYO-KMS, on-prem or customer-VPC, attestation, and a custom SLA.

A credit is the unit of execution for both workflows and agents. In a workflow, most nodes cost one credit, while AI and agent nodes cost 25 credits per call regardless of model. Control flow nodes (switch, wait) are free, and failed node executions are not billed. Talking to an agent costs 25 credits per turn, where a turn is one message you send, on the same credit balance.

Workflow runs pause as a billing hold and agents stop accepting new turns until you have credits again. You can upgrade your plan or buy a one-time top-up. Pile of Credits adds 3,000 credits for $4.99, and Bag of Credits adds 18,000 credits for $19.99. Top-up credits land on your balance right away and never expire, so you can pick up the conversation where you left off.

No. You bring your own provider keys (OpenAI, Anthropic, Google, OpenRouter, Resend, and others) and pay each provider directly. Swirls credits cover orchestration and execution infrastructure only. Enterprise customers can opt into platform-managed keys if they would rather not run their own provider accounts.

You are grandfathered. Your hosted subscription stays active on the original terms: $30 per month, 50,000 credits included, $0.002 credit overage. Your plan was archived (not deleted) when we shipped the new ladder, so no migration is required. You can move to Developer or Team at any time by changing your subscription in the dashboard.

Self-hosted production deployments are available for Enterprise customers that need on-prem or customer-VPC control. The free workflow is local authoring plus cloud deployment for inspection, not a local execution runtime.

Permissions are derived from the SHA-256 hash of the workflow definition; modify the workflow and old tokens stop working. Every execution event lands in an append-only, hash-chained audit log. Team customers get a standard DPA and 90-day audit retention. Enterprise customers get custom DPA, BAA available for healthcare, quarterly attestation reports, SOC 2 / ISO evidence on demand, and security questionnaire turnaround under five business days. See the security page for the full threat model and cryptographic construction.

No. Every paid plan includes unlimited seats. Per-seat pricing doesn't fit a world where agents do most of the work. You pay for what your agents consume (credits) and the organization features your team needs (SSO, audit retention, support tier), not for the number of humans logged in.

Yes. Plan changes take effect at the next billing cycle. If you upgrade mid-cycle, you keep your current plan's included credits for the remainder of the cycle and move to the new plan on renewal. Downgrades follow the same pattern. Cancellations stop billing at the end of the current cycle.

Contact us. Enterprise contracts are priced based on credit volume, deployment surface (multi-tenant, dedicated region, on-prem), encryption posture (managed vs BYO-KMS), retention and attestation needs, support hours, and SLA requirements. Starting point is typically a five-figure monthly commitment.
