Describe your idea and Replit builds a working app in minutes
Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
Continuous AI-powered pentesting for web apps and APIs
Run unlimited automated penetration tests per target that mimic real attacker workflows, validating exploitable paths rather than just flagging CVEs.
Scan authenticated areas, business logic and access controls to surface BOLA, IDOR and privilege-escalation flaws that signature scanners miss.
Cover REST, GraphQL, SOAP and gRPC interfaces, discover shadow APIs and detect API attack patterns alongside your web application surface.
Test live production applications without disrupting them, and rely on audit-ready evidence and continuous mapping to GDPR, ISO 27001, PCI-DSS and HIPAA.
