Testable Synthetic Monitoring

Overview

Testable combines Ping, Port, HTTP, Heartbeat, AI-agent and scripted-flow monitors. Browser, API, transaction and journey checks make it relevant beyond basic uptime alerts, while the range of workflow frameworks offers teams room to reuse existing automation approaches.

When a check fails, Testable can capture timing, assertions, screenshots, logs, traces, run history and protocol details. That evidence can help teams investigate failures rather than merely learn that a check failed. AI assistance can generate and smoke-test an initial browser script, which teams can save and reuse deterministically for later runs.

Key features

• Scripted workflows: Playwright, Puppeteer, Selenium, Postman, Node.js, Python, Locust, JMeter and Gatling are supported. This breadth is useful for teams with established test stacks; it also gives advanced workflows a separate monthly run allowance on the free plan.
• Private-network monitoring: Eligible paid plans can run monitors from self-hosted sources inside a VPC, data center or customer environment. This makes the product a stronger fit for services that public probes cannot reach.
• Notifications: Depending on plan, alerts can go by email, voice, SMS, WhatsApp, webhooks, Slack and Microsoft Teams. Slack can also notify configurable workspace channels and conditions when tests start, finish or fail.
• Status pages: Free includes one basic monitor-backed status page. Paid plans add pages, branding, custom domains, subscribers and operational history, with the number and capabilities varying by tier.
• Enterprise controls: Enterprise includes SSO, custom retention, public and self-hosted sources, and support aligned to ISO 27001, GDPR and CCPA expectations. It also lists 24/7 customer support.

Pricing

Testable is freemium, with no free trial. Paid plans are billed annually at the monthly rates shown; that commitment matters for teams that want to evaluate more than the capped free tier before paying.

• Free — free: Up to 50 monitors, unlimited teammates, one basic status page, and unlimited Ping, Port and HTTP checks at five-minute intervals. Advanced workflows have a separate allowance of 100 runs per month. It is a useful no-cost starting point, but the interval is less responsive than paid schedules and the workflow allowance is modest.
• Solo — 23.17 USD per month (billed annual): 10 monitors, one-minute intervals, unlimited HTTP, Port and Ping checks, 12k custom or AI checks per year, and three basic status pages. It suits a small deployment prioritizing faster basic checks, though its 10-monitor cap is lower than Free's 50.
• Team — 39.17 USD per month (billed annual): 100 monitors, one-minute intervals, unlimited HTTP, Port and Ping checks, 120k checks per year, and 100 full-featured status pages. This is the more natural step for teams that need substantially more monitor capacity and richer status pages.
• Pro — 79.17 USD per month (billed annual): 200 monitors, one-minute intervals, unlimited HTTP, Port and Ping checks, 1.2M checks per year, and 200 full-featured status pages. It fits larger workloads needing higher annual check volume, but remains subject to a 200-monitor cap.
• Enterprise — custom pricing: Configurable monitors and checks, public and self-hosted sources, SSO, custom retention and compliance support. It is the tier for organizations that need those controls or tailored capacity.

Across the paid tiers, the move from Solo to Team to Pro increases monitor, annual check and full-featured status-page capacity. The listed prices are annual-billing rates, so they are not a like-for-like monthly commitment with the free plan.

Platforms

Testable supports API, self-hosted and web platforms. Self-hosted sources are particularly relevant to paid-plan customers monitoring private environments; this is not a broad list of native desktop or mobile apps.

Who it's for

QA and automation teams can use the framework choices and browser-script reuse; SaaS engineering teams can combine API and journey checks with failure diagnostics. Platform and DevOps teams monitoring private infrastructure have a reason to consider eligible paid plans, while agencies and service providers may value the status-page options. Teams needing only frequent basic checks at no cost may find the five-minute free interval too slow.

Pros and cons

Pros

• Many monitor and workflow types: Ping through scripted flows cover a wider range than simple availability checks.
• Useful failure evidence: Screenshots, traces, logs and protocol details can make failed runs more actionable.
• Free basic checks have no execution cap: The constraint is a five-minute minimum interval, not a finite number of Ping, Port or HTTP executions.
• Private sources and status pages scale up: Paid plans can support internal monitoring and add branded, subscriber-ready status pages.

Cons

• Free checks run no faster than every five minutes: Teams needing quicker detection must move to a paid plan.
• Advanced free workflows are capped separately: The 100-run monthly allowance can constrain teams relying on scripted or AI checks.
• Solo has fewer monitors than Free: Its 10-monitor allowance is a trade-off for one-minute intervals and annual custom or AI checks.
• Paid prices assume annual billing: The stated monthly rates come with an annual term.

Alternatives

• Dotcom-Monitor may suit a reader who wants a free allowance of up to 25 targets, five-minute monitoring and two locations.
• HostTracker is a simpler fit if two free monitors checked every 30 minutes are enough, or if a 30-day free trial is preferable.
• New Relic Synthetics may suit readers who want synthetic checks alongside a free allowance that also includes platform-user access and data ingest.

Verdict

Choose Testable if your team needs multiple kinds of synthetic checks, reusable scripted workflows and detailed failure diagnostics, especially when private-network monitoring or status pages matter. Look elsewhere if you need faster checks without an annual paid commitment, or if the free allowance for advanced workflows will not cover your run volume.
