Introducing PulseAPI: Serious API Monitoring Without the Enterprise Price

Today we're opening up PulseAPI to early access.

We built it because we kept running into the same problem: API monitoring tools are either built for enterprises with six-figure budgets, or they're too basic to be useful for anything serious.

If you're a small team, a solo developer, or an early-stage startup that cares deeply about API reliability — there wasn't a great option. So we built one.

The Problem We Kept Hitting

Every time we launched a new project, we'd face the same decision about monitoring:

Option 1: Enterprise tools. Incredibly capable. Also incredibly expensive, complex to configure, and designed for teams with dedicated DevOps engineers. The pricing alone is disqualifying for most small projects.

Option 2: Basic uptime checkers. Cheap, easy to set up. Also too simple — a ping to your /healthz endpoint every 5 minutes doesn't tell you much. No response validation. No latency tracking. Single-region checks. Alert noise through the roof.

Neither option felt right. So we started building.

What PulseAPI Does

PulseAPI is an API monitoring platform built specifically for developers who need real coverage without the overhead.

Multi-region availability checks — We check your endpoints from multiple geographic locations simultaneously. You'll know immediately if your API is unreachable in Europe or Asia-Pacific, not just globally.

Response validation — A 200 OK doesn't mean your API is working. PulseAPI lets you write assertions against the response — status codes, headers, response body content — so you're checking that your API is actually doing what it's supposed to do.

Latency tracking — We track p50, p95, and p99 latency over time. You'll see performance trends, catch degradation before it becomes an outage, and have the data you need for post-mortems.

Intelligent alerting — Alerts go to email, Slack, or webhook. You control the thresholds and escalation rules, so you get notified about real problems, not every transient network blip.

Status pages — Share a public or private status page so your users and team always know what's happening. Incident updates are built in.

Affordable pricing — We're free during Early Access. When we launch paid plans, they'll be priced for the teams we built this for: developers and small teams, not enterprises.

Who It's For

PulseAPI is built for:

• Indie developers and solopreneurs who need professional-grade monitoring for projects that customers depend on
• Small teams that care about reliability but can't justify enterprise pricing or complexity
• Early-stage startups that want solid monitoring foundations before they need to scale
• API-first companies where the API is the product and downtime directly impacts revenue

If you're running a production API that customers depend on, PulseAPI is for you.

What We're Launching With

Early Access includes everything you need to monitor your APIs seriously:

• Unlimited monitors (subject to fair use)
• Multi-region checks from North America, Europe, and Asia-Pacific
• 1-minute check intervals
• Response validation with assertions
• Latency percentile tracking
• Email and Slack notifications
• Public and private status pages
• 90-day data retention

This is everything you need to get real coverage. We'll be expanding capabilities throughout the year based on what we hear from users.

What's Coming Next

We have a clear roadmap and we're moving fast. Next up:

• Advanced alerting — Multi-step escalation policies, on-call schedules, and PagerDuty integration
• Assertion builder UI — Visual assertion creation for teams that don't want to write JSONPath
• API versioning checks — Automatic detection of breaking changes between API versions
• Historical incident timeline — A full audit trail of every incident, response, and resolution

We'll share updates here as features ship.

Try It Free

Early Access is open now and completely free. No credit card required.

Set up your first monitor in under five minutes — add your endpoint URL, configure your assertions, and you're covered.
