Rollbar announces general availability of Session Replay. News provided by. Developer-first replay, linked to errors, with flexible capture controls, privacy safeguards, and AI analysis via open-source MCP - 1,000 free replays for every account. SAN FRANCISCO, Oct. 22, 2025 /PRNewswire/ - Rollbar today announced the general availability of Session Replay, a developer-first way to see exactly what users saw at the moment an error occurred, without leaving the Rollbar workflow. Replays appear alongside each error occurrence to accelerate root-cause analysis and validation of fixes. Unlike standalone replay tools, Rollbar Session Replay is integrated directly into Rollbar's error monitoring and telemetry. Teams can choose when and how to capture sessions by error level, path, or custom events, and control how many seconds before and after an incident are recorded. A new Replay List also supports capturing all sessions when deeper flow analysis is needed. Rollbar Session Replay ships with built-in privacy controls, including configurable PII scrubbing and the ability to delete replays individually or in batch. Each full-page replay is enriched with linked console events, network calls, and logs, with minimal performance impact. Rollbar has also made replay context available in AI coding tools through its open-source MCP integration, allowing AI agents to review a session alongside the error payload, surface insights, generate tests that reproduce the user's path, and even code a fix for the issue. "Developers shouldn't have to guess how an error happened," said Brian Rue, co-founder and CEO of Rollbar. "Session Replay gives you, and your AI, the user's experience and the technical facts, together in one place, so you can fix faster and ship with confidence." Session Replay is available today for all Rollbar customers. Every account starts with 1,000 free replays (higher limits on paid plans). Getting started takes minutes: update to the latest JavaScript SDK and follow the docs to enable capture. See the launch blog for details.

Back in 2010, Ant Group was seeing its business grow rapidly, but the company was also in a conundrum. Alipay – the tech major’s digital payments app – was thriving, with more than 500 million registered users making daily transactions of around US$376 million (2.6 billion yuan).Photo credit: Ant GroupWith the app leading China’s e-wallet space, ecommerce events like Singles’ Day naturally translated into millions of transactions processed via Alipay. In turn, this meant the firm’s database was receiving scores of queries – far more than it could handle. A query works by sending a message to the system, instructing it to take an action such as retrieving a piece of information to process a transaction. Because Alipay’s database was built on a common monolithic structure, it faced regular bottlenecks, including occasional downtimes on various services and an inability to deal with a high volume of queries all at once
