Airbrake vs Xdebug

Airbrake monitors application errors and performance, continuously watching an application stack and sending real-time alerts. Error groups, hotspots, breadcrumbs, backtraces, and aggregations give technical teams context for investigating issues. Deployment Tracking measures errors resolved or introduced with each deployment, while Apdex Scores help interpret user satisfaction. Airbrake supports more than 50 languages, frameworks, and libraries, using agentless and serverless notifiers described as having near-zero application impact. Listed integrations include Bitbucket, GitHub, GitLab, Jira, LogRocket, Okta, OneLogin, PivotalTracker, Slack, Trello, Webhooks, and Zapier. Its mobile notifier supports Android, iOS, Swift, and React Native. The free plan has a quota of 50,000 events per month; paid plans start at $17/mo billed annually. A 30-day trial includes unlimited errors and performance monitoring events, with 30 days of data retention. Accounts have monthly quotas, and excess usage is charged at on-demand rates. Airbrake lists web and API access alongside Android and iOS platforms.

Xdebug is a PHP extension that adds debugging and analysis features to PHP development. Its step debugger lets developers move through code interactively to examine control flow and data structures. It improves var_dump() output and adds stack traces for notices, warnings, errors, and exceptions. Function tracing can record calls, arguments, and invocation locations, with optional variable assignments and return values. The profiler reports execution and memory use in Cachegrind-compatible files, while code coverage can show what runs during PHPUnit tests. Xdebug communicates with IDEs through DBGp, a protocol supported by nearly every PHP IDE, including Visual Studio Code and PhpStorm. Installation instructions cover Linux, macOS, Windows, and Unix-like systems, with compatibility information organized by PHP version. Xdebug itself is free. Paid Pro costs £200 per year for one developer; Business costs £1,000 per year for 2–20 developers. Both paid tiers include email technical support. Xdebug Cloud is described as a relay for situations where a network or firewall blocks direct debugger connections.
