Show HN: Forked – Git for AI agent state (github.com)

Forked is a groundbreaking tool that introduces a version control system for AI agent states, allowing agents to fork, rewind, and replay their structured state with remarkable efficiency. This innovative platform features a side-effect log that ensures actions, such as payments or API calls, are executed only once across retries, maintaining reliability in scenarios where agents might crash. Forked achieves this through a robust architecture that supports rapid state branching and rewinding in memory or using SQLite, with no data duplication, enabling thousands of branches to be processed in a matter of milliseconds. For the AI/ML community, Forked represents a significant advancement in managing agent state, especially for AI applications requiring consistent and reliable execution of tasks. By implementing features like content-addressable storage, atomic effect recording, and efficient diffs that minimize computational overhead, Forked streamlines agent development and debugging. Its versatility across different backend systems—from in-memory solutions to durable cloud storage—offers developers a powerful, open-source resource (Apache-2.0 license) that enhances the reliability and scalability of AI systems. This approach transforms traditional debugging and state management practices, enabling more resilient and sophisticated AI agents.
