I built Nimer because I was spending too much on Claude API costs. Every request was going to Sonnet or Opus even when Haiku could handle it. Nimer fixes that automatically — it routes each request to the right model based on complexity. No code changes needed, just swap the import. Would love your feedback!

Hey Product Hunt! 👋

I'm Majdi, the builder behind Nimer.

I built this after noticing I was routing every single Claude API call to Sonnet by default — simple tasks, complex tasks, didn't matter. I was paying Sonnet prices ($3/M tokens) for things Haiku could handle at $0.25/M. That's a 12x difference.

Nimer fixes this with a one-line change:

# Before
client = anthropic.Anthropic()

# After  
client = anthropic.Anthropic(base_url="https://api.nimer.dev/v1")

That's it. No prompt changes. No logic rewrites. The SDK handles the routing automatically based on task complexity.

Would love to hear from anyone building with Claude — what's your biggest pain point with the API right now?
