I saved 47% on Manus AI credits by building a routing optimizer — here's what I learned
Hey IH! 👋
I've been using Manus AI heavily for the past few months — building side projects, automating workflows, writing code. It's genuinely impressive, but the credit consumption was killing me.
The Problem
Manus has 3 execution modes:
- Chat Mode — free, good for simple Q&A
- Standard Mode — 1 credit/task, handles most coding/writing
- Max Mode — 5 credits/task, for complex multi-step work
The issue? I was defaulting to Max for everything. At $40/month for 39 credits, I was running out by week 2.
What I Did
I tracked 200+ tasks over 6 weeks and categorized which mode each actually needed. The results surprised me:
| Task Type | Best Mode | % of My Tasks |
|-----------|-----------|---------------|
| Quick questions, brainstorming | Chat (FREE) | ~30% |
| Single-file coding, writing, analysis | Standard (1 credit) | ~40% |
| Multi-step research, complex builds | Max (5 credits) | ~30% |
By routing tasks to the right mode, I went from burning 39 credits in 2 weeks to making them last the full month — a 47% savings.
I Built a Tool
I turned my routing logic into a small web tool: Credit Optimizer for Manus AI
It analyzes your prompt and recommends the optimal mode before you run it. Also includes a cheatsheet with 50+ task examples mapped to modes.
I also wrote a detailed breakdown on Dev.to: Manus AI Credit Optimization Cheatsheet
Key Takeaways for Indie Hackers
- Track before you optimize — I assumed I needed Max for everything. Data proved otherwise.
- Free tiers are underrated — Chat Mode handles more than you'd think.
- Small tools can solve real pain — This started as a spreadsheet for myself.
Would love to hear how others are managing AI tool costs. Anyone else building on Manus?
