Execution timeouts are 5 minutes synchronous and 90 minutes asynchronous. Storage: 5GB of files, up to 5 tables, up to 50,000 rows per table, and 30-day log retention.

What happens when the quota runs out, and whether credits reset on the 1st or on the subscription date, are not published. Source conflict, stated as found: the official docs at docs.sim.ai say a free Community plan with 1,000 one-time credits, that is one-time rather than monthly, and give Pro 5,000 and Max 20,000 credits, which does not match the pricing page's 1,000, 6,000 and 25,000 per month; this site does not pick one as definitive, and uses the pricing-page figures while noting that the docs differ. Sim is an open-source project. (Read from sim.ai/pricing on 2026-08-09)
