Bugsly

Bugsly is an AI-powered error tracking and observability platform for software teams. It captures application errors and uses AI to analyze stack traces, explain what went wrong in plain English, and suggest fixes. The platform supports real-time alerts via email, Slack, or webhooks, along with release tracking, session replay, performance monitoring, cron monitoring, and uptime monitoring. Bugsly is designed as a Sentry SDK-compatible alternative, with multi-platform SDKs for React, Next.js, Node.js, Python, FastAPI, Rails, and other environments. It offers a free tier for side projects and individual developers, a Team plan with unlimited users and AI analysis, and Business and Enterprise plans with higher issue volumes, longer retention, SSO/SAML, custom dashboards, and an on-premise option. Unlike event-based billing, Bugsly bills by unique issues, so traffic spikes do not consume quotas. The homepage positions it as a more affordable alternative to Sentry, Datadog, New Relic, Rollbar, Bugsnag, and LogRocket, with AI error analysis included on every plan.
