Replit adds a Performance Agent that scans apps for bottlenecks before publishing

Replit introduced a Performance Agent for scanning apps for runtime bottlenecks in a changelog published on November 13, 2026, alongside new Agent capabilities for running Google Ads campaigns and completing purchases through Stripe's Link wallet.

What changed in the update

• The Performance Agent scans code for performance bottlenecks and is run from Monitoring using a "Run scan with Agent" action, working before an app is published.
• Using the Performance Agent requires a paid Replit plan and edit access to the project.
• A new Google Ads integration lets the Agent create ad campaigns, including copy, images, and conversion tracking, through connected or Replit-managed ad accounts.
• A Replit-managed ad account requires a Replit Pro plan, a personal Workspace, and auto-reload enabled.
• The Agent can now compare products and complete checkout using Link, Stripe's digital wallet, though connecting a wallet alone does not authorize purchases.
• Project sharing was updated so admins and members can share a project with individual Viewers instead of requiring group-level access.

What it means for people who build with AI

The Performance Agent extends Replit's Agent beyond writing code into auditing runtime quality before an app ships, catching bottlenecks that would otherwise surface only after publishing. The Google Ads and Stripe Link integrations push the Agent further toward running a business end to end, letting builders launch marketing campaigns and complete purchases without leaving the Agent workflow, though authorizing a purchase still takes a separate step beyond connecting a wallet.

Other changes in this release

Replit also enhanced its Microsoft Fabric template, which now supports full CRUD database-backed apps along with server-side functions and analytics.
