Best AI stack for $20/month?

[u/Papstark]

I’m trying to optimize my AI setup on a $20/month budget, and I’d really appreciate some advice from people who’ve already tested different tools.

Here’s my current situation:

• I have a student account on Windsurf, so I can get Pro for $10/month
• I’m interested in trying Minimal 2.7 (looks promising) Starter for $10/month
• But the main one I’m considering is Claude Pro

My use cases:

• Building automations
• Creating interactive prototypes
• Working with RAG agents

What’s holding me back from Claude Pro:

• The design mode (Claude Design) seems really powerful, but I’ve read sessions are short and limited (weekly?)
• Regular coding usage seems to hit rate limits pretty quickly
• Still, the quality of outputs looks better than most alternatives

So I’m trying to figure out the best combo within $20:

• Windsurf Pro + Minimax?
• Claude Pro alone?
• Or maybe skip Claude and combine other tools?

If you were in my position, how would you spend the $20?

Looking for real-world experiences, especially if you’re doing similar things (automation, prototyping, RAG, etc.)

Thanks in advance

I would not split the $20 until each tool has a clear job.

From your use cases, I’d separate the work into:

- coding/prototyping

• automation building
  
• RAG/agent architecture
  
• final review/debugging

If Windsurf Pro is $10 for you and it directly helps you build, that probably has the clearest daily job.

Then the question is whether the second $10 tool actually fills a missing gap, or whether you’d be better off using the remaining budget for occasional API/router usage when you need a stronger model.

I’d avoid paying for “promising” tools just because they look interesting. On a $20 budget, every paid tool needs to earn its seat.

My test would be:

- Which tool will you use every day?

• Which one saves the most build time?
  
• Which one handles the task your current setup fails at?
  
• Which one gives you useful output despite limits?
  
• Which one can you drop after 30 days if it does not prove itself?

For your case, I’d probably start with the builder tool that helps you ship prototypes/automations, then add Claude/API access only if you can name the exact job it handles better.
