What you'll learn

  • Parallel agents in Replit enable developers to run multiple tasks simultaneously, significantly speeding up the development process.
  • You can plan tasks, execute them, and merge changes back to the main branch while you continue working in the chat.
  • Core plan users get 1 parallel task, while Pro plan users can run up to 10 tasks at once.
  • The task board displays task status with color codes (gray, blue, green), so you know exactly which stage each task is in.
  • Auto-approval and bulk management tools help you efficiently handle multiple tasks at once without manual steps.

Frequently asked questions

What is the difference between working in the main thread and building in the background?
In the main thread you interact directly with the AI assistant and work interactively. When building in the background, the agent executes your planned task while you continue working in the chat.
How many parallel tasks can I run at the same time in Replit?
This depends on your plan. Core plan users can have 1 parallel task, while Pro plan users can run up to 10 tasks simultaneously.
How do I merge changes from a background task back to main?
After a background task completes, Replit shows you the changes. You can review them and then merge them back to your main branch. The session covers best practices to avoid merge conflicts.
How do credits work with parallel agents?
Replit calculates credit usage for each parallel task separately. The session goes into detail on how to manage your credits efficiently when running multiple tasks at once.
