Expirity checks domain expiry (RDAP/WHOIS), full DNS record sets, nameservers, and SSL certificate status on a schedule (daily on the free tier, near-real-time on paid), and writes a change log every time something differs from the last check - registrar change, NS change, new/removed DNS record, cert reissue, etc. Alerts go out by email, Slack, Discord, or WhatsApp. There's a REST API and CSV/Namecheap/GoDaddy/Route 53 import if you're bringing in an existing portfolio.
Better Stack is an eBPF-based, AI SRE observability tool that helps you ship higher-quality software faster. Monitor everything from websites to servers. Schedule on-call rotations, get actionable alerts, and resolve incidents faster than ever. Connect your Kubernetes or Docker clusters to gather logs, metrics, and network traces with eBPF. No code changes required.

Expirity's answer
Agencies and MSPs managing domains across multiple clients, plus freelance developers and small businesses monitoring their own portfolios. The common thread is anyone responsible for a domain going down, a cert expiring, or DNS getting silently changed - and who can't afford to find out from a client's phone call.
Better Stack's answer:
Engineering teams of all sizes โ from startups to Fortune 500 companies.
Expirity's answer
Expirity combines domain expiry, full DNS record monitoring, nameserver/registrar change detection, and SSL certificate tracking in one tool - instead of stitching together WHOIS reminders, a separate SSL checker, and a PSA workaround. For agencies and MSPs specifically, it adds client folder organization, per-client alert routing, and role-based team access (admin/editor/viewer), so one account can manage domains across many clients without exposing them to each other.
Better Stack's answer:
Better Stack is a modern observability tool that leverages eBPF and OpenTelemetry to make tracing work for you.
Expirity's answer
Domain and DNS problems tend to be invisible until they're urgent - a registrar warning email lands in spam, an auto-renew fails silently, or a compromised registrar account gets its nameservers swapped without anyone noticing until email stops working. Expirity was built to close that gap: continuous monitoring of expiry, DNS, and SSL status with alerts the moment something changes, rather than relying on a reminder email that might never be seen.
Better Stack's answer:
We are software builders at Better Stack.
CEO is a software engineer, COO is a software engineer and you guessed it; CTO is an engineer, too.
Weโre helping developers ship higher quality software faster.
Expirity's answer
Most domain-monitoring tools are either built for individuals (generous on price, no multi-client structure) or built for MSPs (client folders and RBAC, but starting around $99/mo with no free tier). Expirity sits in between: a genuinely useful free tier (50 domains, no credit card), and a Pro/Agency structure ($19-$49/mo) that adds client folders and team roles without the higher price floor competitors in the MSP-focused space charge. Registrar import (Namecheap, GoDaddy, Route 53) also means bringing in an existing portfolio takes minutes, not manual entry.
Better Stack's answer:
You get an unrivaled price-to-performance ratio. Forget sampling and ingest all your data, or decrease your costs by 30x.
Better Stack's answer:
The primary technologies used to build Better Stack are eBPF for low-level, high-performance instrumentation and ClickHouse for storing and querying large volumes of observability data efficiently.

Better Stack bundles uptime monitoring, incident management, on-call scheduling, log management, and status pages into one dashboard. For cloud monitoring, it sits closer to the external/uptime layer than to deep infra telemetry. It watches your cloud-hosted endpoints, collects logs, and gives you on-call and a status page without stitching together separate products. - Source: dev.to / 12 days ago

Better Stack bundles uptime, real Playwright/Chromium browser checks, incident management, on-call, logs, and status pages in one product โ and its native on-call and escalation are the best in this list. You author in JavaScript or paste from Playwright codegen, and you get trace-viewer artifacts on failure, an MCP integration, and a Terraform provider. - Source: dev.to / about 1 month ago
Better Stack (formerly Better Uptime + Logtail) is the most ambitious all-in-one in this list โ it bundles uptime monitoring, on-call scheduling, incident management, status pages, AND log management into a single platform.
