.replit Config File Invalid on Replit
Replit displays config errors or your custom run command doesn't execute. The .replit configuration file has syntax errors or missing required fields.
The .replit file controls how your app builds and runs on Replit.
Error Messages You Might See
Invalid .replit configuration
Failed to parse .replit file
run: command not found
Common Causes
- TOML syntax errors (missing quotes, invalid characters)
- Missing 'run' key for deployment command
- Wrong build tool command (e.g., mvn instead of ./gradlew)
- File encoding issues or line endings
- Incorrect module path for multi-module projects
How to Fix It
Validate .replit TOML syntax using a TOML linter. Ensure 'run' command is correct (./gradlew bootRun for Gradle projects). For Spring Boot, use './gradlew bootRun' or java -jar. Set appropriate working directory if needed. Verify file is saved as plain text with Unix line endings.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
