Recost

Your API costs fully visible.

Recost shows you exactly what code is burning money before your API bill explodes. It maps cost to endpoints, flags waste like duplicate calls and bad loops, and simulates scale impact. With AST analysis and runtime tracking, you don’t just track spend, you control it before it gets out of hand.

Hey Product Hunt! 👋

We’re the team behind Recost.

We built this after watching teams unknowingly blow through API budgets.

At a hackathon, a team shipped a feature making ~200 concurrent API requests. It worked perfectly… until their API key got revoked. No visibility. No warning. Just everything shutting off.

Recost gives you a cost intelligence layer for your APIs, so you can see and control cost before it becomes a problem.

What Recost does

🔍 Static analysis (VS Code extension)

  • Detects API calls across your codebase

  • Maps endpoints to files, functions, and features

  • Surfaces cost risks before runtime

Detection is still improving as we expand coverage across frameworks and edge cases.

💸 Cost attribution

  • Cost per endpoint, provider, and feature

  • See what’s actually driving spend

⚡ Runtime tracking (Python SDK)

  • Live request volume, latency, and cost

  • Real-time sync to dashboard

🚨 Waste detection

  • Duplicate calls, loops, polling issues

  • Suggestions to reduce cost

📈 Forecasting

  • Simulate scale and estimate feature cost

  • Catch worst-case scenarios early

🌐 Dashboard

  • Unified view of API usage and cost

  • Trends and drilldowns

What’s coming next

  • MCP integration for API graph + cost intelligence

  • Built-in AI for better detection and estimation

  • Team pricing plans

Why we built this

Every part of engineering has visibility.
Logs. Metrics. Errors.

API cost doesn’t.

Recost makes cost visible at the same level as your code.

Free plan

We’re building fast and want real feedback.

We’re also building this in the open, feel free to check it out or contribute on GitHub(https://github.com/recost-dev).

Where do API costs feel the most unpredictable right now?
