Description

StateFabric is a compact infrastructure layer designed for AI agents that require additional context beyond just the chat history. When an agent begins to utilize tools and operates over extended sessions without restarting, relying solely on retained messages is insufficient; it becomes essential to track the following aspects: what events transpired, what changes occurred in the state, which tools were utilized, and what context should be factored into the upcoming model iteration. To address these needs, StateFabric maintains an append-only event log throughout agent operations, enabling the extraction of relevant context from this data. Currently, it offers a range of features, including durable session management and event storage, user/model/tool event timelines, the ability to reconstruct session states from recorded events, and a streamlined model-facing context. Additionally, it includes a user-friendly dashboard for analyzing sessions, inspecting raw payloads, reviewing compaction artifacts, and monitoring usage patterns. Furthermore, StateFabric supports integration with Google ADK through the package @statefabric/adk and facilitates direct usage in Node/REST environments via @statefabric/client, making it adaptable for custom runtimes. This versatility ensures that AI agents can operate more efficiently and effectively in complex environments.

Description

rrweb is a widely used open-source session replay library for recording and replaying user sessions on the web. The platform helps developers, observability teams, analytics companies, product teams, and support tools understand exactly what happened during a user session. rrweb captures the rendered DOM, user interactions, clicks, scrolls, hesitation, UI changes, and other session events so teams can replay experiences with context. Observability teams can attach replays to errors to see what users did before something broke. Product and experience analytics teams can watch real user journeys to understand behavior and improve design decisions. Bug reporting teams can use rrweb to capture precise reproduction steps instead of relying on vague issue descriptions. rrweb Cloud adds managed infrastructure for storage, indexing, querying, insights, deduplication, PII filtering, and replay processing. The platform also supports AI workflows by turning recordings into structured event streams that agents and LLMs can read. By combining open-source replay capture, managed cloud infrastructure, extensible playback, and AI-ready session data, rrweb gives teams a flexible way to build replay-powered products.
