Developers can now debug and evaluate AI agents locally with Raindrop's open source tool Workshop
Our take
Developers can now debug and evaluate AI agents locally with Raindrop's newly launched open-source tool, Workshop. This robust solution provides a lightweight SQL database that captures every action taken by AI agents in real-time, allowing users to analyze errors and improve performance. With its self-healing eval loop, Workshop empowers coding agents to autonomously fix logic errors. Available for macOS, Linux, and Windows, this tool fosters a community-driven approach to AI development.
The launch of Raindrop AI's open-source tool, Workshop, marks a significant evolution in AI development. By providing developers with the ability to debug and evaluate AI agents locally, this tool addresses a critical gap that has been felt since the rise of agentic AI. The timing of this release is particularly noteworthy, coinciding with the increasing complexity of AI systems and the need for robust observability tools. As we see in emerging platforms, like Clawdmeter turns your Claude Code usage stats into a tiny desktop dashboard, the demand for tools that can simplify and enhance user experience is paramount.
Workshop offers a lightweight SQL database file to track every token, tool call, and decision made by AI agents, which is a game-changer for developers looking to understand the intricacies of their models. This real-time telemetry not only enhances the debugging process but also alleviates concerns regarding privacy associated with traditional methods that often require sending data to external servers. The ability to see a comprehensive view of what an agent has done empowers developers to learn from mistakes and optimize their systems rapidly. This is particularly important in a landscape where developers are increasingly focused on building secure and efficient AI applications.
Moreover, the self-healing eval loop feature of Workshop represents a significant leap in how AI agents can autonomously improve themselves. This functionality allows agents like Claude Code to read traces, execute evaluations, and autonomously fix errors, which is a profound shift in AI capabilities. The implications of this are far-reaching: as agents become more self-sufficient, we can expect to see a new wave of productivity enhancements across various sectors. This shift aligns with broader trends in automation and AI integration into everyday workflows, echoing sentiments from recent discussions around platforms like YouTube viewers watch 2 billion hours of Shorts on TVs each month, where user engagement is increasingly driven by seamless and intuitive interactions.
The decision to release Workshop under the MIT License further emphasizes Raindrop AI's commitment to fostering community involvement and innovation. By encouraging contributions from developers, the tool not only enhances its own capabilities but also builds a collaborative ecosystem that can adapt to the fast-evolving needs of AI development. This approach is vital in a landscape where the rapid pace of change can leave legacy systems struggling to keep up. It reflects a forward-thinking attitude that recognizes the importance of collective intelligence in driving technological advancements.
Looking ahead, the introduction of tools like Workshop raises critical questions about the future of AI development and debugging. As more developers adopt these innovative solutions, we may witness a significant shift in how AI applications are built and maintained. Will we see a new standard in debugging practices that prioritizes local solutions and community contributions? The answers to these questions will shape the trajectory of AI technology, making it more accessible and efficient for developers everywhere. As we stand on the brink of this new era, it invites us to consider how these advancements will empower not just developers but also the end-users who will ultimately benefit from more reliable and capable AI systems.
Observability startup Raindrop AI’s new open source, MIT Licensed "Workshop" tool, launched today, gives developers something that they've likely wanted, perhaps subconsciously, since the agentic AI era kicked off in earnest last year: a local debugger and evaluation tool specifically designed for AI agents, allowing devs to see all the traces of what their agent has been doing in a single, lightweight Structured Query Language (SQL) database file (.db)
It functions as a local daemon and UI that streams every token, tool call, and decision to a local dashboard—typically hosted at localhost:5899—the moment it occurs. By visiting their localhost, developers can then see everything their agent was up to — including mistakes or errors — and identify what went wrong, when, and ideally, discern why. It's all stored in a single .db file, which takes up relatively little memory, according to a X direct message VentureBeat received from Ben Hylak, Raindrop's co-founder and CTO (and a former Apple and SpaceX engineer).
This real-time telemetry eliminates the latency of traditional polling and addresses a growing developer concern regarding the privacy of sending local traces to external servers.
The tool is available for macOS, Linux, and Windows. It can be installed through a one-line shell command that automates binary placement and PATH configuration for bash, zsh, and fish shells. For developers who prefer to build from source, the repository is hosted on GitHub and utilizes the Bun runtime.
The product: establishing a self-healing eval loop
The platform’s standout feature is the "self-healing eval loop," which allows coding agents like Claude Code to read traces, write evals against the codebase, and fix broken code autonomously.
In a practical application, if a veterinary assistant agent fails to ask necessary follow-up questions, Workshop captures the full trajectory. Claude Code then reads this trace, writes a specific eval, identifies the logic error in the prompt or code, and re-runs the agent until all assertions pass.
Compatibility and ecosystem integration
Workshop is compatible with a broad range of programming languages, including TypeScript, Python, Rust, and Go.
It integrates with popular SDKs and frameworks such as the Vercel AI SDK, OpenAI, Anthropic, LangChain, LlamaIndex, and CrewAI. It is also designed to work seamlessly with various coding agents, including Claude Code, Cursor, Devin, and OpenCode.
Licensing and community implications
Workshop is released under the MIT License, ensuring it remains free and open-source for all users. This permissive licensing is intended to foster community contribution and allow enterprise users to maintain data sovereignty.
Hylak noted on X that the tool was built to provide a "sane" way to debug agents locally, changing how their team and early customers build autonomous systems.
To celebrate the launch, Raindrop offered limited-edition physical merchandise to users who installed the tool and executed a specific "drip" command.
