EVM-UI – visual tool to interact with EVM-based smart contracts
Hey HN!
We've built https://evm-ui.com, a free tool that allows you to interact with smart contracts visually.
It started as an internal project while building Web3 apps for clients — we needed something more flexible and lightweight than Remix or Etherscan's UI.
Unlike Etherscan or Polygonscan, you don't need to verify and open-source your smart contract to get a working UI. Paste the ABI (or load it from a template) and proceed.
With EVM-UI, you can
- Import contracts by address + ABI, or paste ABIs directly
- Read/write functions with auto-generated UI (supports all Solidity types, including arrays)
- Execute actions with smart inputs (dropdowns, min/max helpers, etc.)
- Switch between EVM chains, testnets, or local RPCs within one workspace
- Use developer tools (Keccak256, ABI encoder/decoder, address utils)
- Share environments with your team and your client
We'd love to receive your feedback, ideas, or constructive criticism.
P.S. We're aware that signup emails may go to spam - fixing that now. EVM-UI is a clean, intuitive, and powerful tool for interacting with smart contracts.
Unlike Etherscan or Remix, it lets you work with any contract via ABI — no verification required.
The auto-generated UI for functions (with full Solidity type support) and built-in dev tools make it ideal for both quick testing and client demos.
Being able to switch chains and share environments is a huge bonus. Great job! This is exactly what I was looking for!
Great job, the UI feels snappy and intuitive.
Curious to see where you take it next. Hi! This looks like a great project. Just wanted to check — are the collaboration features also available for free? Yes — collaboration features are currently 100% free.
In the future, we may introduce paid plans for larger teams or organizations. That said, we plan to keep them free for individuals and small teams. Let us know if you have any suggestions or use cases — we’re shaping the roadmap based on real user needs! Just checked it out this is seriously good. Super lightweight, intuitive, and finally something that makes quick contract interactions painless. Great stuff! Being able to work with a contract without verification on Etherscan was exactly what I needed for quick debugging evm-ui saved me time interacting with unverified contracts for clients.. just paste the abi and go. highly recommend if you're over remix or etherscan. any plans to add save common input presets per contract? Really handy tool! Simple to use and solves a real pain point.
