Greptile Summary

This PR addresses two key infrastructure issues in the Sim application: a domain migration for telemetry endpoints and conditional redirect configuration for hosted vs self-hosted environments.

The primary change involves updating all telemetry endpoint URLs from sim.ai to simstudio.ai across four files: telemetry.config.ts, lib/telemetry.ts, app/api/telemetry/route.ts, and the instrumentation configuration. This ensures consistency in where telemetry data is sent when no custom TELEMETRY_ENDPOINT environment variable is configured. The telemetry system collects anonymous usage data including feature usage statistics, error rates, and performance metrics while explicitly avoiding personal information, workflow content, or sensitive data.

The second major change modifies next.config.ts to conditionally apply domain redirects only when running the hosted version of the application. The redirects handle migration from the old simstudio.ai domain to the canonical www.sim.ai domain, but these redirects are now gated behind an isHosted check that verifies if NEXT_PUBLIC_APP_URL equals https://www.sim.ai. This prevents redirect conflicts in development, staging, or self-hosted environments where such redirects would interfere with local testing or alternative hosting configurations.

These changes work together to support a domain migration strategy while maintaining proper functionality across different deployment environments. The telemetry configuration changes ensure data continues flowing to the correct collection endpoint, while the conditional redirects provide a clean separation between hosted and non-hosted application behavior.

Confidence score: 5/5

• This PR is extremely safe to merge with minimal risk of production issues.
• All changes are straightforward URL updates and conditional logic that properly isolates hosted vs non-hosted behavior.
• No files require additional attention as the changes are simple, well-targeted, and maintain backward compatibility.
