Monitoring and analytics

All 41

Alphabetical. Checked on 2026-09-04; anything that did not answer says so.

• Airbrake
  Error monitoring and alerting, one of the earlier hosted exception trackers.
  Predates most of what it competes with.
• Anteon
  Kubernetes monitoring using eBPF, so service maps come from the kernel rather than from instrumented code.
  Observability without touching the application.
• Baremetrics
  Subscription analytics that reads the billing system and produces the revenue metrics from it.
  Reads Stripe so nobody has to build the dashboard.
• Better Stack
  Logs, metrics, traces, uptime and on-call in one product, sold against assembling four vendors.
  One bill instead of the observability shopping list.
• Carbone
  Generates documents from templates and JSON: PDF, DOCX, XLSX and the rest of the office formats.
  Report generation without a report server.
• devActivity
  Analytics over engineering activity, producing contribution and delivery metrics from repository data.
  Measures the team, which is always contentious.
• DocRaptor
  HTML to PDF over an API with proper CSS Paged Media support, which most converters do badly.
  Takes page breaks seriously, which is the whole difficulty.
• Export SDK
  PDF generation with a template editor, an API and no-code integrations.
  Design the document, then call it.
• Future AGI
  Evaluation and observability for agents, aimed at diagnosing why a run failed rather than only that it did.
  Debugging for systems with no stack trace.
• Heap
  Analytics that captures every interaction automatically, so questions can be asked about events nobody thought to instrument.
  Records first, decides what mattered later.
• Helicone AI
  A proxy in front of model calls that records cost, latency and content, and routes between providers.
  One line of config to find out what the models cost.
• Highlight.io
  Open-source session replay and error monitoring. The address now serves LaunchDarkly.
  Absorbed: the URL now belongs to somebody else.
• Image-Charts
  Renders charts as images from a URL, for emails and PDFs where JavaScript cannot run.
  Charts for the places a chart library cannot go.
• Instatus
  Status pages and incident communication, fast to set up and fast to load when everything else is down.
  The page that must stay up when nothing else does.
• KeenIO
  Managed event streaming on Kafka, so analytics events can be collected without operating a cluster.
  Kafka, without the cluster.
• Laminar
  Open-source tracing and evaluation for agents, built around finding the step where a run went wrong.
  A stack trace for something that has none.
• Langfuse
  Open-source tracing, evaluation and prompt management for model applications, self-hostable.
  Observability for models, without sending the traces away.
• LogRocket
  Session replay joined to console output, network activity and errors, so a bug report becomes a recording.
  Shows you what the user did, not what they remember doing.
• Maple
  Open-source observability built on OpenTelemetry, so the instrumentation is not vendor-specific.
  Standard instrumentation, replaceable backend.
• Maxim AI
  A gateway in front of models and agents providing routing, guardrails, governance and observability.
  A control plane between your code and the models.
• Middleware
  Full-stack observability with real-time monitoring, positioned on cost against the incumbents.
  Competes on the observability bill.
• Mixpanel
  Product analytics built around events and funnels, now with replay, experiments and flags attached.
  Event analytics, from before every tool had it.
• Oh Dear
  Uptime, certificate expiry, DNS, broken links and cron monitoring in one small product.
  Covers the checks that only matter once.
• Opik
  Open-source evaluation and tracing for agent systems, from the Comet team.
  Evaluation treated as a permanent fixture, not a one-off.
• Pagerly
  On-call scheduling and incident response run inside Slack, where the team already is.
  Incident management without a second window.
• PDFBlade
  Listed as an HTML to PDF API. The domain now serves an unrelated online gambling site. Do not follow this link expecting the original product.
  Repurposed: the domain now serves something else entirely.
• PDFShift
  HTML and CSS to PDF over an API, with high-fidelity rendering and no browser to maintain.
  Someone else runs the headless Chrome.
• Pinecone
  Managed vector search at large scale, the product that made vector databases a category.
  Named the category, then had to defend it against Postgres.
• Pirsch
  Cookie-free open-source analytics, light enough that the script is not a performance decision.
  Analytics with no consent banner attached.
• Plausible
  Lightweight open-source analytics with no cookies and no cross-site identifiers. Self-hostable.
  Counts visits without building a profile.
• PoeticMetric
  Free and open-source privacy-first web analytics, licensed to stay that way.
  Free as in freedom, and says so first.
• PostHog
  Product analytics, replay, flags and experiments in one open-source platform, now diagnosing and fixing issues too.
  Absorbed four product categories and kept the source open.
• Quivr
  Listed as an open-source retrieval assistant. The address now serves a customer support automation product.
  Repositioned into a different market.
• Repohistory
  Keeps GitHub traffic statistics past the fourteen days GitHub retains them for.
  Exists because GitHub throws the data away.
• Respan
  Model observability, evaluation, prompt optimisation and a gateway, unified in one control plane.
  Routing and watching, in one place.
• Rollbar
  Real-time error monitoring connecting exceptions to releases and session replays.
  Ties the error to the deploy that caused it.
• Segment
  A customer data platform that collects events once and routes them to every downstream tool. Now part of Twilio.
  One integration instead of thirty analytics snippets.
• Sentry
  Error and performance monitoring built for developers, with the source open and the stack trace as the centre of the product.
  Made the stack trace a shared artefact.
• Tinybird
  ClickHouse behind managed ingestion and API endpoints, so an analytical query becomes a URL.
  The query is the endpoint.
• umami
  Open-source privacy-first analytics, self-hostable, one of the most widely adopted alternatives to the incumbent.
  Small, self-hosted, and enough.
• Zoho Apptics
