CodeTracer is a user-friendly time-traveling debugger designed to support a wide range of web3 programming languages.

EDB is a source-level debugger for Solidity execution with stepping, locals, watches, and breakpoints when you need IDE-grade visibility into contract behavior onchain or in tests.

Simbolik is a powerful Solidity debugger that combines traditional breakpoint debugging with symbolic execution, enabling developers to explore every possible execution path and uncover vulnerabilities with precision. Available as a VSCode extension, Simbolik integrates seamlessly into existing workflows, offering breakpoint-style debugging, Solidity and EVM-level inspection, and formal verification capabilities.

Abi Ninja is a browser UI for calling contracts with known ABIs, pasted ABIs, or decompiled bytecode, with proxy-aware reads across many networks including your locally running Hardhat or Anvil node.

Tenderly provides transaction simulation, trace debugging, alerting, and Virtual TestNets for contracts. Builders use it to replay a failing transaction, watch deployed contracts, and test against a forked network.

Semgrep is a pattern-based static analysis tool with rulesets for Solidity vulnerabilities. Builders run those rules over a codebase to catch known vulnerable patterns and style issues before review.
