    FourSight vs Cronitor

    Looking for a Cronitor alternative?

    Cron and heartbeat monitoring plus full uptime, SSL, DNS, and status pages — one flat plan instead of a point solution.

    FourSight is a Cronitor alternative for teams that want cron/heartbeat monitoring and uptime, SSL, DNS, and status pages in one tool: heartbeats with 5-field cron expressions and grace periods ship in the Growth plan ($40/mo) alongside 100 multi-region uptime monitors — replacing Cronitor (from ~$7/mo) plus a separate uptime product.

    Why switch?

    FourSight vs Cronitor: the breakdown

    Cronitor has owned the cron-job monitoring niche for a decade, and it earns the position: excellent documentation, native SDKs for Python/Node/Ruby/PHP and shell, job telemetry with runtime metrics, and a developer experience that made 'cronitor.link pings' a default pattern. Paid plans start around $7/mo (as published July 2026 — verify with the vendor). If scheduled jobs are the only thing you monitor, this page won't talk you out of it.

    The consolidation argument is the real one. Cronitor is a point solution: the same team that needs cron monitoring almost always also needs website uptime checks, SSL expiry alerts, and a status page — and ends up buying a second product for those. Cronitor has added basic uptime checks, but its depth is jobs, not infrastructure monitoring.

    FourSight approaches it from the other side: a full uptime platform — HTTP, SSL, DNS drift, domain expiry, keyword, ping, port — with heartbeat/cron monitoring as one of the 8 first-class check types. Heartbeats support 5-field cron expressions, grace periods, and miss thresholds, and feed the same incident pipeline, escalation policies, and status pages as everything else. (The Cronitor pricing comparison multiplies out the per-monitor math.)

    The honest trade: Cronitor's job telemetry (capturing runtime, output, and metrics from inside the job) is deeper than FourSight's ping-URL model. If you need per-run metrics and log capture, Cronitor wins that feature. If you need 'alert me when the job doesn't run' plus a complete monitoring stack under one flat price, that's the FourSight lane.

    Advantages

    Why teams choose FourSight over Cronitor

    One tool instead of two

    Cronitor covers cron jobs well, but you still need an uptime/SSL/status-page product beside it. FourSight's Growth plan ($40/mo) covers heartbeats, uptime, SSL, DNS, domain expiry, keyword, port, and ping in one monitor list with one incident pipeline.

    Heartbeats with 5-field cron expressions

    Define expected schedules with standard cron syntax, grace periods, and miss thresholds. Your job pings a unique URL; FourSight alerts when the ping doesn't arrive on schedule.

    4-region quorum for the uptime half

    Heartbeat checks are inherently single-source, but your uptime checks shouldn't be. FourSight validates HTTP/SSL/DNS checks from 4 regions with quorum consensus.

    Status pages and escalations included

    Escalation policies and hosted status pages ship with the same plan — no add-on products to price out.

    Pricing

    Pricing: FourSight vs Cronitor

    Cronitor is fairly priced for what it does — the consolidation math is where FourSight wins. Compare the one-tool bill against the two-tool bill.

    Scenario FourSight Cronitor
    Cron monitoring only, small scale Growth — $40/mo (heartbeats unlock here, alongside everything else). Overkill if cron is truly all you need. Cronitor from ~$7/mo, or its limited free tier. For cron-only, Cronitor is the cheaper pick — honestly.
    Cron + uptime + SSL for one product Growth — $40/mo total. Heartbeats, 100 uptime monitors, SSL/DNS/domain checks, 5 status pages, escalations. Cronitor (~$7–49/mo depending on volume) + a separate uptime/status-page tool (typically $15–30/mo) = ~$25–80/mo across two dashboards.
    Uptime first, cron jobs later Start on Starter — $16/mo (50 uptime monitors), upgrade to Growth when you need heartbeats. Two separate purchasing decisions, two vendors, two incident pipelines.

    Cronitor figures as published July 2026 — verify with the vendor; its pricing scales with monitor volume and team size. FourSight prices are from our public pricing page (annual billing ≈ 25% discount).

    Cronitor's paid plans start around $7/mo and scale with monitor volume and team size (as published July 2026 — verify with the vendor). It's fair pricing for a focused tool — but it covers one job.

    FourSight Starter ($16/mo): 50 monitors for uptime and ping with 1-minute intervals, Slack/webhook alerts, and 2 status pages — the uptime half of the consolidation.

    FourSight Growth ($40/mo): heartbeat/cron monitoring plus all 8 check types, 100 monitors, 30-second intervals, escalation policies, and 5 status pages. For many teams that replaces a Cronitor subscription and an uptime tool at once.

    Full FourSight plan details are on the pricing page — five flat tiers, annual billing ≈ 25% off, no per-monitor surprise fees.

    Honest take

    Who should choose which

    Comparison pages usually pretend the writer's tool wins every scenario. Here's the fair version — when FourSight is the right call, and when Cronitor still is.

    Choose FourSight if…

    FourSight is the better fit when cron monitoring is one requirement among several.

    • You're currently paying for (or about to buy) both a cron monitor and an uptime tool — Growth at $40/mo replaces both.
    • You want cron-miss alerts flowing through the same escalation policies and status pages as your uptime incidents.
    • You need SSL, DNS drift, or domain-expiry coverage that a cron specialist doesn't offer.
    • You want multi-region quorum on the uptime half instead of single-source checks.

    Choose Cronitor if…

    Cronitor is still the right pick in these cases — credit where due.

    • Scheduled jobs are genuinely all you monitor, and ~$7/mo beats $40/mo for that single job.
    • You want deep job telemetry: runtime metrics, output capture, and per-run history via native SDKs.
    • You instrument jobs in code with language SDKs rather than adding a curl ping to the end of a script.

    Migration

    How to migrate from Cronitor to FourSight

    Migrating heartbeat monitors is mostly a URL swap. There's no importer — monitors are re-created manually — but each takes under a minute, and most teams re-create 20 monitors in under 15 minutes.

    Estimated time: 15–30 minutes for a typical setup
    1. 1

      List your Cronitor monitors

      From the Cronitor dashboard or API, list each monitor's name, schedule, and grace period. That's the whole spec you need to carry over.

    2. 2

      Sign up and pick Growth

      Heartbeat monitors unlock on the Growth plan ($40/mo). Start on Free first if you want to migrate your uptime checks and try the platform before paying.

    3. 3

      Create matching heartbeat monitors

      For each Cronitor monitor, create a FourSight heartbeat with the same cron expression and grace period. FourSight generates a unique ping URL per monitor.

    4. 4

      Swap the ping URLs

      In your crontabs, systemd timers, CI pipelines, and scripts, replace the Cronitor ping call with a curl to the FourSight heartbeat URL. Deploy the change.

    5. 5

      Consolidate the rest

      Re-create your uptime, SSL, and DNS monitors in the same dashboard, wire escalation policies, and cancel both the Cronitor subscription and the second uptime tool when the parallel run looks clean.

    No credit card. No import tool needed — monitors are just URLs plus a check type.

    FAQ

    Common questions

    Is Cronitor better at cron monitoring than FourSight?

    In depth of cron-specific tooling, yes — Cronitor has job telemetry, runtime metrics, and language SDKs that FourSight doesn't match. FourSight's heartbeat monitors cover the core job (alert me when a scheduled task doesn't run, with cron expressions, grace periods, and miss thresholds) and bundle it with uptime, SSL, DNS, and status pages in one plan.

    What does a FourSight heartbeat monitor look like in practice?

    You create a heartbeat monitor with a schedule (a 5-field cron expression) and a grace period. FourSight gives you a unique URL; add a curl call to the end of your cron job or CI script. If the ping doesn't arrive on schedule, FourSight opens an incident and alerts your channels.

    Can I migrate from Cronitor to FourSight?

    Yes — list your Cronitor monitors, create matching heartbeat monitors in FourSight (Growth plan), and swap the ping URLs in your crontabs and scripts. There's no importer; most teams re-create 20 monitors in under 15 minutes since each is just a name, a schedule, and a URL swap.

    Does FourSight support cron expressions like Cronitor?

    Yes — heartbeat monitors accept standard 5-field cron expressions plus a grace period and miss threshold. If the expected ping doesn't arrive within schedule + grace, FourSight opens an incident and alerts your channels.

    Can FourSight capture job output and runtime metrics?

    No — that's Cronitor's telemetry strength and we won't claim parity. FourSight's heartbeat model is the ping-URL pattern: it tells you reliably that a job ran (or didn't) on schedule, not how long it took or what it printed.

    Is there a free tier for heartbeat monitoring?

    Not on FourSight — heartbeats unlock on Growth ($40/mo). If you need free cron monitoring, Healthchecks.io's 20-check free tier is the honest recommendation; FourSight's value is the consolidation, not free cron checks.

    What happens if my whole server dies — do heartbeats catch that?

    Yes, that's the point of the dead-man's-switch model: no ping arrives, so the alert fires. Pair heartbeats with FourSight HTTP/ping monitors on the same host and you'll know whether it's the job or the whole box.

    The verdict

    Cronitor is the best pure cron-monitoring tool, and if that's your only need, buy it. FourSight is what you buy when the cron jobs are one line item on a longer monitoring list — heartbeats, uptime, SSL, DNS, and status pages under one $40 flat plan instead of two subscriptions and two dashboards.
