Airbrake vs AppSignal

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.

AppSignal is a cloud application-monitoring service for developers, with error tracking, performance monitoring, logs, and tracing. Error tracking groups exceptions with backtraces and the deployment linked to each issue. Performance monitoring covers response times, throughput, slow endpoints, and slow queries. Log management provides full-text search, attribute filters, saved queries, live tail, and pattern-based alerts. Distributed tracing, transaction tracing, and log correlation are available. AppSignal lists support for Ruby, Elixir, Node.js, JavaScript, Python, Go, Java, PHP, and Rust, with integrations including Slack, GitHub, Jira, Linear, GitLab, and PagerDuty. Its MCP server lets AI assistants such as Claude, Cursor, and Zed query production errors, traces, and deploys. The free plan costs nothing and includes 30K requests, 1GB logging, five-day retention, and unlimited users, teams, applications, and dashboards. Paid access is $279 a year, billed yearly at $23.25/month, with 250K requests per month. A 30-day full-featured trial requires no credit card. AppSignal says it does not charge overages or stop monitoring when limits are crossed.
