Opslane

Opslane is an open source error tracking and session replay tool that goes on to write the fix. It records every session and captures every error, identifies the bugs that actually affect users, and opens a pull request with a proposed fix for the developer to review and merge. A developer installs the SDK, which works with Next.js, Nuxt, React, Vue and vanilla JavaScript. Opslane then watches for two kinds of problems: errors that are thrown, and silent failures where nothing crashes but users give up, such as clicking a button repeatedly with no result. A daily digest, shown in Slack, lists the issues that matter, how many users each affected and links to the session replay. Items are split into those that need a human decision and those with a fix ready to merge. The vendor states it only opens a pull request it can verify, by reproducing the failure and then confirming the fix passes CI. Coding agents can also pull the digest and issue details through MCP tools and link their own pull requests back to an issue. It is aimed at web development teams that want their error backlog prioritized by real user impact and turned into reviewable code changes. The site says it is free to start. It does not publish prices for any paid plan.
