The Web3 developer community is split between two frameworks: Hardhat and Foundry. Let me compare both after using each for production projects.
Hardhat: The JavaScript Standard
Pros:
- TypeScript/JavaScript (familiar to Web2 devs)
- Rich plugin ecosystem
- Integrates with VS Code seamlessly
- Great for teams transitioning from Web2
Cons:
- Slower tests (JavaScript overhead)
- More complex setup for advanced features
- npm dependency hell
Foundry: The Rust Speed Demon
Pros:
- Written in Rust (blazing fast)
- Tests in Solidity (no language switching)
- Built-in fuzzing and invariant testing
- Simple, clean architecture
Cons:
- Steeper learning curve for JavaScript devs
- Smaller plugin ecosystem
- Command-line focused (less GUI tooling)
My Experience
I started with Hardhat, switched to Foundry, now use both:
- Hardhat for frontend integration and deployment
- Foundry for contract development and testing
Test speed comparison: Foundry runs my test suite in 2 seconds vs Hardhat’s 45 seconds.
Winner: Foundry for serious contract dev, Hardhat for quick prototyping.
