Frequently Asked Questions
What is Retrace?
Retrace is an execution replay engine that records every LLM call, tool call, cost and error made by an AI agent. By adding a single decorator to a Python or TypeScript agent—compatible with LangChain, CrewAI and LlamaIndex—the SDK captures each step, allowing you to replay a run, fork from the exact point of failure, modify inputs or prompts, and re‑execute to verify a fix before deployment. The platform provides a UI for live streaming of traces, step‑by‑step replay, and interactive RCA analysis, including span timings, costs and error details. It also offers automated quality checks such as groundedness gaps, statistical drift detection, budget or loop limits, and guardrails that can halt or block problematic actions in real time. Users can search raw JSON spans or use semantic search to locate bugs quickly, and share trace tapes for collaboration. Retrace’s free tier includes up to 1,000 recorded traces per month, with no infrastructure to manage beyond signing in with GitHub. GateOnAI Score: 60/100.
What is Cursor?
Cursor is an AI coding agent that helps developers build ambitious software by turning ideas into code. It offers autonomous agents that can run in parallel across tools, with an autonomy slider letting users choose between targeted edits (Cmd+K) or full‑autonomy generation. The Mission Control interface provides a grid of live window previews for quick navigation, accessible via View > Mission Control, F3, or double‑tap. Cursor supports the latest Grok models, cloud‑based agents, code hosting, AI code reviews, and integration of third‑party models (billed separately). Pricing includes tiered plans with shared usage pools that refresh weekly, and higher tiers grant larger pools, priority model access, and additional features such as faster responses and ad‑free scrolling. GateOnAI Score: 87/100.
