Overview

Bugsink is an error tracker that shows the stacktrace, code and local variables behind each production failure. It accepts events from Sentry's open-source SDKs, so existing clients connect by changing the DSN. It groups related errors into issues, alerts on them, supports search by release, environment or user, and applies sourcemaps to minified code.

Best for: Teams on Sentry SDKs wanting error tracking on their own servers or EU-hosted at fixed cost
Pricing: Free evaluation tier for 15K monthly events, then hosted plans at €16, €50 and €158 per month for 75K, 600K and 3M events, rising to €568 (15M) and €1,288 (50M); self-hosted pricing is not shown in the captured text.
Runs on: Self-hosted

Trade-offs

Free tier allows one user and retains only 5K events
Retention is capped at the plan's monthly event count
Hosted option is EU-only; no choice of region
Above 50M monthly events, pricing is quoted on request

How this score is made up

Each dimension is scored out of 100 and combined into the headline score using fixed weights.

MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.

Measured, but not part of the score

Useful to know, but not a mark for or against the product — so these do not affect the ranking.

Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
