San Francisco, California, United States
What it is
Rulebricks is a visual decision-management platform for teams automating business processes. Domain experts and process owners can build and update business rules through a no-code interface, then publish API endpoints. Decision tables can also be used to create embeddable calculators with application branding. Teams can import Excel models to generate rules, coordinate multiple rules in workflows, and use the test management UI or API to check rules before deployment. What-if backtests help assess the impact of changing rule conditions. Listed integrations include Salesforce, Excel, Zapier, and PostgreSQL, and the maker says it can connect wherever an API can be called. Developer tools include a JavaScript component for embedding the interface and programmatic options for managing tenants, users, rules, and tests. Deployment choices include major cloud providers, on-premises, and air-gapped environments. The free Design plan is free, billed annually, and allows up to 10 rules and flows, 1,000 monthly executions, and five team members. Paid plans start at $200/mo (annual).
