AppSignal vs Measure

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.

Measure is monitoring software for teams responsible for production mobile apps. It collects crashes, ANRs, bug reports, session replays, performance traces, and network activity in one dashboard. Replays can include clicks, navigation, logs, HTTP calls, memory and CPU usage, and stack traces. An app-health view tracks adoption, crash rates, launch times, and app size. Adaptive Capture changes collected data without requiring an app update. SDK support covers Android, iOS, Flutter, React Native, and Kotlin Multiplatform; access is also listed for API, web, and self-hosted deployments. Email and Slack provide alerts and daily summaries, with Slack debugging through Measure Agent. An MCP server connects telemetry to several coding agents. Measure says its software is fully open source. The FREE plan costs nothing with 5 GB monthly and 30 days retention. PRO costs $50 a month, includes 25 GB and 90 days retention, and charges $2 GB/month.
