Visual trace replay for AI apps to fix bugs in one click
Glassbrain is an innovative visualization tool designed for AI developers seeking to streamline debugging and bug fixing in their AI applications. It captures every step of an AI's inference process as an interactive visual trace tree, enabling developers to easily explore, swap inputs, and replay executions without redeploying the model. Its snapshot mode offers deterministic replays for consistent troubleshooting, while live mode interacts directly with the actual stack for real-time debugging. The platform also provides auto-generated fix suggestions, referencing precise trace data with a simple one-click copy, and a diff view to highlight exactly what changed between iterations. Shareable replay links facilitate collaborative debugging within teams. Compatible with popular AI models like OpenAI and Anthropic, Glassbrain requires just two lines of code for integration, making it accessible for developers of all levels. Its free tier offers up to 1,000 traces per month, making it an appealing choice for startups and individual developers looking to improve AI reliability efficiently.
Pros
- Interactive visual trace trees for in-depth debugging
- One-click input swapping and replay without redeploying
- Snapshot mode ensures deterministic replays
- Auto-generated fix suggestions with trace referencing
- Easy integration with minimal code (two lines)
Cons
- Limited free tier (1,000 traces/month) may be restrictive for high-volume users
- Primarily focused on AI model debugging, may not suit non-AI applications
- Relatively new tool; ecosystem and community support may be limited
Best for
- • Troubleshooting errors in AI inference pipelines
- • Debugging complex prompt engineering workflows
- • Testing and validating model updates before deployment
- • Collaborative bug fixing with shareable replay links
Pricing: Based on its features and free tier, Glassbrain likely offers a freemium model with a free plan that includes 1,000 traces per month, and paid plans for higher volume and additional features. Exact pricing details are not publicly confirmed.
