Plan Mode is 3 months old: Requesting honest reviews & tips

Tips & Tricks
1

Hey all,

I’ve been using Plan Mode since it dropped back in September 2025, now I’m wondering if it has been helping or hurting.

  • Is It Redundant: To a degree, it’s nice to think through something before going, but wouldn’t Build Mode take more or less the same steps (depending on autonomy level)?
    • I suppose it does allow you to see how the agent is thinking through a solution, and if you understand enough, you can provide feedback.
  • Arbitrary Code: It isn’t clear how Plan Mode is billing me. Sure, it’s typically under $2, but it isn’t clear if it’s how long it works on something or how much code it has to review, or something else (forgive the ignorance on this one).
  • Does it Save Time? I’m honestly curious how others have been doing and if you have any tips or tricks in Plan Mode.

I think this thread would help the masses :slight_smile:

Ooooh Nooooooooooooooooooo! Do not even hint at removing plan mode!! :blush:

Planning an app is mission critical. Never just dive in and tell your developer to start hacking code without planning first. That way lies madness my friend!

:laughing:

I suppose I do my planning outside of Replit, so usually I’m just piecemealing my epics over to the agent for implementation.

Agree with Steve here. I’m a religious user of Plan mode. It’s absolutely not redundant.

Remember, plan mode isn’t just for “planning”. It is for debugging and testing:

Saying to agent things like: “X has gone wrong, I need you to analyse the console errors and the codebase and give me a plan to fix it”.

And then going back and forth a few times, questionning the plan before you agree to switch to build mode.

i agree, plan mode is nice as it is good to settle on your desired UI/UX before generating the backend.

and correct me if i’m wrong but you can always see the cost if you expand the “worked for X seconds” widget.
