I Built 3 MVPs for Under $100: The Token/Credit Conservation Guide

I burned through $200 in credits my first month. Here's how I built better apps for 80% less.


The Hard Truth

Tokens and credits equal money. Wasting them equals wasting cash. Most beginners burn through credits because they don't understand how the pricing works or how to build efficiently.


8 Money-Saving Strategies

1. Build the Skeleton First

  • First prompt: Just structure and navigation

  • Second prompt: Add one feature at a time

  • This catches layout issues early before you've built everything

2. Batch Your Changes

❌ Wasteful:

  • "Change color to blue" [send]

  • "Make font bigger" [send]

  • "Add padding" [send]

✅ Smart:

  • "Change color to blue, increase font size to 18px, and add 20px padding to all buttons"

3. Use the Diff/Edit Mode

  • In Bolt: Enable "diffs" feature to edit existing code

  • In Lovable: Use Visual Edit for style changes

  • Editing uses WAY fewer credits than rewriting entire files

4. Lock Your Files (Bolt-specific)

  • Lock files that work perfectly

  • Prevents AI from "helpfully" breaking things that aren't broken

5. Start with Templates/Examples

  • "Build something like [well-known app]" gives AI a clear reference

  • Reduces back-and-forth clarifications

6. Be Surgical with Fixes

❌ Wasteful: "My app has issues, fix it"

✅ Smart: "In Header.tsx, line 23, change the onClick handler to toggle the menu"

7. Copy-Paste Working Patterns

  • Keep a personal doc of prompts that worked well

  • Reuse successful patterns for similar features

8. The "$5 Rule"

  • Before sending a prompt that will use lots of credits, ask: "Would I pay $5 for this change right now?"

  • If no, refine your prompt or wait


Free Tier Strategies

  • Use free daily credits for learning and testing

  • Build serious projects once you understand the platform

  • Lovable: 5 free credits/day = one meaningful feature addition

  • Bolt: 300K tokens/day = enough for small changes and testing


When to Upgrade

Upgrade when: You're hitting free limits AND actively building something people want

Don't upgrade when: Still figuring things out, building for practice


Real Cost Breakdown

  • Landing page: 10-15 credits/tokens

  • Simple CRUD app: 20-30 credits/tokens

  • Complex app with auth/database: 40-60 credits/tokens

  • Heavy debugging session: 10-20 credits/tokens


Key Takeaway

"The cheapest way to build is to think before you prompt. Five minutes of planning saves 50 credits of fixing."
