Perplexity says two engineers worked with hundreds of AI coding agents to build CobbleDB, a custom Rust database replacing DynamoDB reads in its search stack. The case shows coding agents contributing at real infrastructure scale while keeping production execution outside the agents’ permissions.

Key Takeaways

  • ✓Two engineers coordinated hundreds of AI coding agents to build the custom Rust CobbleDB database
  • ✓CobbleDB replaces DynamoDB read paths in Perplexity’s search stack
  • ✓Agents built the system but were not allowed to run the database, separating coding from production authority
