Pulsetic alternative: a close comparison, honestly drawn

What Pulsetic does well

Pulsetic has clearly put effort into the parts customers actually look at, and its entry pricing is aggressive.

• Multi-region checking is built into the pricing model, with the number of checking regions rising by tier. Undownable checks from a single vantage point today, so this is a straightforward advantage.
• The free plan includes three status pages, which is more than most free tiers hand out.
• Its entry paid plan is priced slightly below Undownable Pro, with one minute intervals.
• Higher tiers reach thirty second intervals, faster than Undownable offers.
• Long history retention on the upper tiers, measured in years rather than months.
• Status pages are attractive and easy to set up, which matters more than engineers like to admit when a customer is looking at it.
• Screenshots on incidents at the higher tiers, useful evidence when a page is technically up but visibly broken.

If checking from many geographies is the requirement, that is a real reason to choose Pulsetic and no amount of feature listing on our side changes it.

Where it starts to hurt

• The free plan is email alerts only. Chat and webhook alerting starts on a paid plan, so a free Pulsetic account cannot page your Slack.
• Teammates are gated by tier and only start appearing above the entry plan, so a two-person team is already a tier decision.
• Keyword checking is a paid feature rather than something the free plan can do.
• SMS and voice call alerts arrive as a monthly allowance rather than being unlimited.
• Unlimited status pages are a mid-tier feature rather than a Pro-level default.

Side by side

Where Undownable differs

• Every alert channel on the free plan. Email, ntfy, Telegram, Slack, Discord, and webhooks are all available at no cost, so a free account can genuinely page your team rather than only emailing you.
• Unlimited team members on Pro with no per-seat charge and no tier gate on collaboration.
• Deeper check types: JSON API checks with dot-notation assertions into the response body, DNS record checks, and push heartbeats for cron jobs and self-hosted monitoring boxes.
• SSL checks that validate the full chain and the hostname rather than only reading an expiry date, with escalating warnings at 30, 14, 7, and 1 days out and an all-clear on renewal.
• A degraded state distinct from down, so a warning like a near-expiry certificate is alerted without being counted against your uptime.
• Exactly-once alert delivery backed by a ledger, flap suppression, and confirmation thresholds so a single blip never pages anyone.
• Keyword matching on every plan including free, rather than as a paid upgrade.
• First class ntfy support including self-hosted ntfy servers with access tokens.
• A first-party MCP server alongside a versioned REST API, both with least-privilege tokens pinnable to a single team, plus maintenance windows you can drive from a deploy script.

Who should stick with Pulsetic

• You need checks run from multiple geographic regions to distinguish a global outage from a regional routing problem. This is the clearest reason to choose Pulsetic.
• You need thirty second intervals, which Undownable does not offer.
• You want several status pages on a free account, which Pulsetic gives and Undownable does not.
• You need multi-year history retention.
• You need SMS or voice call escalation.
• Incident screenshots are something you would actually use.
