6 free alternatives to Bugsink

BugSnag's free plan includes 1 user, error monitoring with 7.5K events per month, performance monitoring with 1M spans per month, 7 days of data retention, and access to 50+ platforms plus 30+ third-party integrations. That makes it a broader monitoring starter than Bugsink if you want both error and performance coverage in one place. It also adds a wider integration footprint, which helps if your workflow spans multiple tools. It falls short on raw error-event volume, because Bugsink allows 15K monthly events on the free tier. Switch here if you care more about multi-platform coverage and spans than a higher error cap.

• Beats Bugsink: Performance monitoring and 50+ platforms
• Falls short: Lower monthly error-event cap than Bugsink
• Who should switch: Switch to BugSnag if you want a broader monitoring stack with performance data and many integrations in a solo-friendly free plan.

Sentry's free tier includes one user account, error monitoring and tracing, email alerts and notifications, and 10 custom dashboards. It is a better fit than Bugsink when your main need is a more complete debugging workflow around dashboards, tracing, and alerting rather than just exception capture. The free tier is still single-user, so it is aimed at solo use, but the dashboard and tracing layer may be enough to replace a narrower error tracker. It falls short on stateful retention and published monthly volume because the supplied free-tier items do not list those limits, while Bugsink states both events and retained history clearly. Choose Sentry if dashboards and tracing matter more than exact quota simplicity.

• Beats Bugsink: Error monitoring plus tracing and dashboards
• Falls short: Bugsink states clearer event and retention quotas
• Who should switch: Switch to Sentry if you want a solo free tier centered on tracing, alerts, and dashboards.

GlitchTip's free plan includes up to 1,000 events per month, error tracking, unlimited projects, and unlimited team members. Its biggest draw is collaboration, because it removes the user and project ceiling that constrains Bugsink's free hosted tier. It is also straightforward for teams that want a free, perpetual hosted plan without a credit-card requirement. The tradeoff is volume: 1,000 events per month is much smaller than Bugsink's 15K monthly events, so it fits only very light usage. If your team size matters more than event volume, or you are running multiple small projects and need them all on a free plan, GlitchTip is the easier swap.

• Beats Bugsink: Unlimited projects and unlimited team members
• Falls short: Much lower monthly event allowance than Bugsink
• Who should switch: Switch to GlitchTip if collaboration and multiple projects matter more than event volume.

Better Stack's free tier includes 10 monitors and heartbeats, Slack and e-mail alerts, 100,000 exceptions per month, 5,000 session replays, 30 GB of metrics, 3 GB each of logs, web events, and traces for 3 days, plus one status page. That is much broader observability headroom than Bugsink's hosted free tier, especially if you want monitoring, alerts, and incident-facing features in the same package. It falls short if you only need simple error tracking, because Better Stack is a larger observability suite rather than a focused error tracker. It is the right move when the free plan should cover monitoring and incident response, not just exceptions.

• Beats Bugsink: Much larger observability quotas and status pages
• Falls short: Less focused than Bugsink for simple error tracking
• Who should switch: Switch to Better Stack if you need free monitoring, alerts, and incident tooling beyond error tracking.

Bugfender's free plan includes up to 100,000 log lines per day, 24-hour log retention, up to 2,000 customer devices, unlimited apps, unlimited team members, and a daily summary email. That is a very different kind of free tier from Bugsink, and it gives far more room for device-heavy logging than a small hosted error tracker. It is best when you need remote logs, device context, and broad app coverage rather than a tight error budget. It falls short on error-tracking specificity, since the supplied free-tier items are centered on logs and devices, not on retention of exception events. Switch if your debugging workflow starts with logs and client-side device data.

• Beats Bugsink: Device count and log-volume headroom
• Falls short: Less specific to exception-centric error tracking
• Who should switch: Switch to Bugfender if you need free remote logging across many devices and apps.

Inspector's free plan includes 30K transactions per month, unlimited events, unlimited hosts and apps, up to 3 team members, live chat support, and AI Bug Fixer access. Compared with Bugsink, it gives more headroom on team size and application coverage, while still staying free for a meaningful amount of traffic. The transaction cap is higher than Bugsink's 15K monthly events, which makes it appealing for small PHP projects that need more room before paying. It falls short if you are not in the PHP ecosystem, because Inspector is positioned around PHP frameworks and code instrumentation. Pick it when your stack is PHP and you want a free tier with more room to grow.

• Beats Bugsink: Higher transaction cap and up to 3 team members
• Falls short: Narrower PHP-focused scope than Bugsink
• Who should switch: Switch to Inspector if you build in PHP and want more free-tier transaction headroom.
