Swetrix is an open-source, privacy-focused web analytics platform that collects anonymised, cookie-less metrics about website traffic, sessions, performance and client-side errors. It provides both a self-hostable Community Edition and a managed cloud offering with additional features.

Key Features

• Cookie-less, privacy-first tracking that collects anonymised pageviews, events and session data without cross-device identifiers
• Core analytics: top pages, traffic sources, UTM campaigns, geolocation and device/browser breakdowns
• Session analytics and user flows to visualise journeys and pageview sequences
• Funnels, goals and custom events for conversion tracking and behaviour analysis
• Real-user performance monitoring (TTFB, DNS, TLS, render and other frontend timing metrics)
• Client-side error tracking with aggregation by page, browser, device and geolocation
• Feature flags and rollout controls to target segments and measure feature impact
• Experiments / A/B testing (managed cloud) with exposure tracking and statistical comparisons
• Revenue analytics integrations (Stripe, Paddle) and CSV/API data export for portability
• Lightweight TypeScript tracking script and real-time React dashboard built for low overhead
• Deployable via Docker with a backend API, MySQL for core data, ClickHouse for analytics storage and Redis for caching

Use Cases

• Privacy-compliant website analytics for small businesses, blogs and SaaS sites that want to avoid cookie banners
• Monitoring frontend performance and client-side errors to detect regressions and improve page speed
• Running feature flags and A/B experiments (cloud) to optimize conversions and measure feature impact

Limitations and Considerations

• The Community Edition (self-hosted) provides core analytics, sessions, funnels, performance and error tracking but lacks some managed-cloud features (experiments, revenue analytics, AI insights, and built-in alert/email reports)
• GeoIP accuracy in self-hosted deployments depends on the chosen GeoIP database and may be less precise than the managed cloud's premium DB
• Scaling analytics requires appropriate ClickHouse and infrastructure configuration; self-hosters must manage upgrades, backups and operational costs

Swetrix bundles core web analytics, performance monitoring and error tracking in a privacy-first package suitable for self-hosting or using a managed cloud. It focuses on essential, low-footprint analytics while offering expanded features in its cloud offering.

GlitchTip is an open-source error tracking and observability platform that implements a Sentry-compatible intake API. It provides error aggregation, basic APM-style transaction visibility, and uptime monitoring via a Django backend paired with an Angular frontend.

Key Features

• Sentry-compatible event intake allowing existing Sentry client SDKs to report errors and transactions.
• Error aggregation and issue grouping with searchable issue lists and event details.
• Application performance monitoring that surfaces slow requests, database calls, and transaction traces.
• Uptime monitoring (ping-style checks) with alerts delivered via email or webhooks.
• Deployable with Docker and Docker Compose, Kubernetes Helm chart available for cluster installs.
• Backend built on Django with worker tasks via Celery; PostgreSQL is the primary data store.
• Optional cache/message broker usage of Valkey/Redis for improved performance and Celery brokering.
• Hosted SaaS offering available alongside comprehensive self-hosting docs and Docker images.

Use Cases

• Centralize and triage runtime exceptions and stack traces from web and mobile apps using existing Sentry SDKs.
• Monitor web application latency and identify slow endpoints and database calls for performance troubleshooting.
• Keep track of site uptime with scheduled pings and receive alerts when endpoints fail to respond.

Limitations and Considerations

• Some enterprise SSO workflows (notably SAML multi-tenant SSO) are a known area of ongoing discussion and work; available social/OAuth providers are supported via django-allauth but full SAML multi-tenant support is not yet standard.
• For larger deployments, Valkey/Redis is recommended for Celery brokering, caching, and sessions; Postgres-only mode is experimental and may yield lower performance.
• Feature parity with commercial Sentry varies; a few advanced grouping, fingerprinting and analytics features are under active development or improvement.

GlitchTip is suited for teams that need a budget-friendly, open-source alternative for error tracking and basic observability while retaining compatibility with Sentry client tooling. It supports both small single-server installs and larger containerized deployments with documented configuration and upgrade paths.

Telebugs is a lightweight, self-hosted error tracking system designed as a focused alternative to Sentry. It collects, groups, and notifies teams about application errors while keeping all data under your control.

Key Features

• Ruby on Rails backend with a Turbo + Stimulus-driven UI to minimize JavaScript framework complexity
• Compatible with existing Sentry SDKs and uses DSN-style endpoints for drop-in integration
• Docker-based installer with a single-command setup, automatic SSL provisioning, and optional auto-updates
• Default storage with SQLite for minimal administration and a simple deployment footprint
• Solid Queue for background jobs (designed to avoid a Redis dependency and reduce operational complexity)
• Error grouping, full backtraces, breadcrumbs, tags, contexts, and attachments to aid debugging
• Team management, invite links, email notifications and PWA push notifications for real-time alerts
• One-time licensing model with unlimited events/projects (no recurring event quotas)

Use Cases

• Primary error tracker for small to medium teams that want on-premise control and low operational overhead
• Backup or staging/trunk environment to preserve expensive SaaS quotas while retaining compatible SDK workflows
• Regulated environments (GDPR/CCPA) or agencies that require private hosting and full data ownership

Limitations and Considerations

• Telebugs focuses strictly on error tracking; performance monitoring/APM, profiling, and session replay are not provided
• Telebugs does not include a built-in Sentry data import tool; migrating from Sentry requires a custom script or manual migration
• Default stack (SQLite + Solid Queue) favors simplicity; very high-volume, multi-node deployments may require custom scaling or alternative DB choices
• License restricts reuse and redistribution of the product source outside the allowed scope; each license covers a single domain

In summary, Telebugs is a pragmatic, minimal-dependency error tracker for teams that prioritize privacy, simplicity, and predictable hosting costs. It suits projects that need reliable error aggregation and notifications without the complexity of heavyweight observability platforms.
