14 days of Team for every new account, and new docs

Every new account starts with 14 days of Team, free and without a card: 5-second checks, phone alerts, status pages on your domain. Then pick a plan or stay on Free; nothing is deleted.
Docs for developers: grouped by topic, searchable (press /), with copyable code, a complete API reference, an OpenAPI spec, webhook payloads and signatures, and guides. Every page is also available as Markdown for your agent: see llms.txt.
Published check addresses at /ips, to allow checks through firewalls and bot protection.
Feedback from inside the app: the link next to Sign out goes straight to us.

Your agent can now take the first look at every incident, while your team is paged as usual.

Alert sources: Prometheus Alertmanager and Grafana, Sentry, Datadog, AWS CloudWatch (with SNS signature checks), or any JSON. Related alerts group into one incident with a timeline.
Deploy markers: tell Pulsefast what you shipped, and the agent gets the recent deploys with every incident.
Three ways to connect an agent: Claude run by Pulsefast in your own Anthropic account, your own agent by webhook, or pulsefast listen on any machine, with no public URL needed.
Humans stay in charge: risky actions wait for approval from chat, anyone can take over, and fixes arrive as pull requests for review.

Early access: ask us to join.

Pulsefast is open to its first users:

Checks every 5 seconds for websites, APIs and TCP ports, and heartbeats for cron jobs.
Failures confirmed from a second region before anyone is woken, and a hanging site is caught while the first check is still waiting.
Alerts where your team already is: Slack, Discord, Microsoft Teams, Telegram, PagerDuty, incident.io, ntfy, Pushover, email, webhooks, and phone calls and SMS on Team and Business.
Status pages, on your own domain, with incident notices and email updates for subscribers.
Maintenance windows, an API, uptime badges, and a one-click import from UptimeRobot.
Your whole team included on every paid plan. No per-seat pricing.
