Steprun.ai sandboxes your AI-generated code into step-by-step REPL sessions, with the following benefits:
- Escape if-else hell – Focus on the current execution path only, skipping exponential branching complexity.
- Debug line by line – Catch and fix errors instantly–line by line, no post-hoc tracing.
- Declare now, implement later – Define function stubs first, fill logic only when called (like human iterative coding).
- Hibernate & restore – Persist sessions mid-execution, ideal for long-running processes and iterative workflows.
