Compute credits power agent runs and evaluation cycles. Free plans get 50 credits per month, Pro plans get 150. Pro plans stay online when usage exceeds the monthly cap — overages are metered rather than blocked.
Yes, you can change your plan at any time. The changes take effect at the start of your next billing cycle.
SpinStack reads your description of what the agent is supposed to do, generates test inputs grounded in that context, scores each run, and surfaces regressions. When a run fails, it inspects the trace, isolates the cause, and applies a fix — iterating until the workflow converges on reliable behavior.
Enterprise is tailored to the complexity and scale of the workflows you run — custom evaluation rubrics, private tool integrations, and dedicated support. We scope it with you based on your team's needs.
