Production-grade observability and enterprise controls
Everything you need to run tools in production while meeting enterprise observability and security requirements. Every execution is logged. Every error is caught. Every action is audited. RBAC, SSO and version control are built in.
Full deployment history
Deploy your app in one click from the UI or via CLI. Backend logic runs on dedicated workers, frontend is served by the platform. Every deployment is tracked with who deployed what, when and which version. Roll back to any previous deployment instantly.
Full execution history
Every script and flow run is logged with input, output, duration and errors. Search, filter and replay past executions to debug issues in seconds.
Error handlers & retries
Configurable retry count with exponential backoff. Custom error handler scripts per step. Apps that don't break silently at 2am.
RBAC & SSO
Granular permissions control who can build, view and execute apps. SSO with SAML, OAuth and LDAP.
Audit logs
Track every user action: logins, permission changes, script edits, resource access. Full audit trail for compliance, security reviews and incident investigations.
Git sync
Sync your workspace with GitHub or GitLab. Push and pull scripts, flows and apps as code. Use your existing CI/CD and code review workflows.
