Robotalp has a permanent free plan, but it is tight: 10 robots at a 5-minute frequency, 1 user, 1 status page without a custom domain, email alerts only, a cap of 30 alerts, and no access to the Port, API, Safe browsing, Blacklist, DMARC, or DNS robot types. CronAlert's free plan includes 25 monitors at a 3-minute interval, SSL monitoring, a status page, unlimited email/Slack/Discord/webhook/push alerts, and read-only API access.

CronAlert vs Robotalp: Feature Comparison and Pricing

Q: How much does Robotalp cost?

Robotalp prices its Personal plan on a credit slider rather than fixed tiers. As of July 2026, the entry point is 2,000 credits — about 20 robots — at $13.54/mo billed monthly or $11.28/mo billed yearly, scaling up to roughly $41.59/mo (yearly) for 10,000 credits / 100 robots. The Team plan is $124.48/mo billed monthly ($103.73/mo yearly) for 20,000 credits / 200 robots, 10 users, 5 workspaces, and 5 status pages. CronAlert's flat plans are $0 (Free, 25 monitors), $5/mo (Pro, 100 monitors), $20/mo (Team, 500 monitors), and $50/mo (Business, unlimited).

Q: What is a cheaper alternative to Robotalp?

For HTTP uptime, SSL, and status-page monitoring, CronAlert costs a fraction of Robotalp at every fleet size. Robotalp's entry Personal plan is $13.54/mo for about 20 robots; CronAlert Pro is a flat $5/mo for 100 monitors at 1-minute intervals with keyword assertions, heartbeat monitoring, and a full read-write API included. Where Robotalp earns its price is breadth: page speed, DMARC, blacklist, safe-browsing, port, and DNS check types that CronAlert deliberately does not offer.

Q: Does CronAlert offer page speed, blacklist, or DMARC monitoring like Robotalp?

No. Robotalp's pitch is 12 check types in one dashboard — uptime, page speed, SSL, port, API, DNS, DMARC, blacklist, safe browsing, and more. CronAlert deliberately focuses on HTTP/HTTPS checks, SSL certificate monitoring, keyword and content assertions, and heartbeat monitoring for scheduled jobs, and does that slice at flat commodity prices. If you need domain-reputation checks like blacklist or DMARC monitoring, Robotalp covers ground CronAlert does not.

Q: When is Robotalp worth it over CronAlert?

When you actually use the breadth: page speed tracking, DMARC and blacklist reputation monitoring, safe-browsing checks, and port/DNS robots across 20+ probe locations, all in one dashboard. Agencies managing many client domains also like its bulk website wizard. If your real usage is uptime checks, SSL, a status page, and cron job monitoring, CronAlert covers that at $0–5/mo where Robotalp's credit plans start at $13.54/mo for a fifth of the monitors.

Robotalp (robot.alp) is a budget-friendly all-in-one monitoring platform from Mantiksal Ltd: a dozen check types — uptime, page speed, SSL, port, API, DNS, DMARC, blacklist, safe browsing, and more — checked from a network of 20+ locations, with status pages, a well-reviewed dashboard, and a bulk "website wizard" that agencies love for onboarding client sites in one pass. It consistently rates 4.7–5.0 on G2, Capterra, and Trustpilot, and it positions itself as one of the most cost-effective tools in the category.

CronAlert plays in the same budget end of the market but makes the opposite bet: instead of twelve check types on credit-based pricing, it does the uptime slice — HTTP checks, SSL, content assertions, heartbeats, status pages — at flat prices from $0. As with our HetrixTools and Pulsetic comparisons, the useful question is which check types you actually need. Pricing below was verified in July 2026 on Robotalp's pricing page — their credit slider means your exact number will vary, so confirm before committing.

Where Robotalp leans

First, breadth of check types. Robotalp's twelve robots cover categories CronAlert deliberately skips: page speed tracking over time, domain-reputation checks like DMARC, DNS blacklist, and Google Safe Browsing status, plus raw port and DNS record monitoring. If an email domain landing on a blocklist or a page-speed regression is a failure mode you genuinely need alerts for, Robotalp bundles it where CronAlert would leave you assembling separate tools.

Second, agency ergonomics. The bulk website wizard sets up monitors for a list of domains in one pass, and workspaces (5 on the Team plan) separate clients cleanly. Reviewers running web agencies cite exactly this. CronAlert covers the same organizational need with teams and per-team monitor pools, but has no equivalent one-shot bulk wizard — imports go through the API or the UptimeRobot migration importer.

Third, a larger probe network. Robotalp checks from 20+ locations worldwide. CronAlert runs on Cloudflare's edge and offers multi-region quorum checks across five regions on Team and Business plans — enough to kill false positives, but fewer selectable vantage points than Robotalp exposes.

Where CronAlert pulls ahead

The first answer is price at every fleet size. Robotalp's Personal plan starts at $13.54/mo billed monthly for 2,000 credits — about 20 robots — and reaching 100 robots costs roughly $41.59/mo even on yearly billing. CronAlert Pro is a flat $5/mo for 100 monitors at 1-minute intervals, with keyword assertions, heartbeats, maintenance windows, three status pages, and the full API included. That is not a rounding-error gap; at the 100-monitor mark it is roughly 8× cheaper.

Second, a genuinely usable free plan. Robotalp's free tier is 10 robots at a 5-minute frequency with email alerts only, a 30-alert cap, and six of the twelve robot types locked out. CronAlert's free plan is 25 monitors at a 3-minute interval with SSL monitoring, a status page, and unlimited alerts through email, Slack, Discord, webhooks, and push. For a side project, CronAlert free replaces a paid Robotalp seat; our free tools roundup shows how the free tiers across the market stack up.

Third, heartbeat monitoring for scheduled jobs. CronAlert treats cron jobs, backups, and background workers as first-class monitors: the job pings a unique URL on success, and silence beyond a grace period alerts you. It is the check type that catches the failures HTTP monitoring can't see, and it is included from the $5/mo Pro plan.

Fourth, no credit math. Robotalp's slider is transparent as credit systems go, but different robot types still consume different credit amounts, so capacity planning means arithmetic. CronAlert's tiers are one number: how many monitors you get. Predictability is the whole pricing model — the same reason we push back on metered pricing in our Checkly comparison.

Finally, API-first and AI-assistant-ready. Every CronAlert plan includes the REST API (read-only on free, read-write from Pro), and CronAlert ships an MCP server so Claude Code, Cursor, or Windsurf can create and manage monitors conversationally.

When to pick each

Pick Robotalp if: you want page speed, DMARC, blacklist, safe-browsing, port, and DNS checks in one dashboard, you value a large selectable probe network, or you run an agency that will use the bulk wizard and workspaces weekly. It is a well-built, fairly priced tool for the all-in-one niche.

Pick CronAlert if: your requirement is knowing that sites, APIs, SSL certificates, and scheduled jobs are up — and being alerted everywhere your team lives when they are not. You get 25 monitors free (2.5× Robotalp's free robot count, at a faster interval, with real alert channels), and 100 monitors with content assertions and heartbeats for a flat $5/mo.

How to decide

List the check types you will actually configure in the first month. If page speed, DMARC, blacklist, or safe-browsing checks are on the list, Robotalp bundles real value CronAlert doesn't sell. If the list reads uptime, SSL, status page, and cron jobs, you are choosing between $13.54/mo for 20 monitors and $5/mo for 100 — plus a free tier generous enough that you may not pay at all. Our buyer's guide has a fuller checklist for matching tool to requirements.

Then run the real test: Robotalp's 14-day trial and CronAlert's free plan can watch the same endpoints simultaneously. Trigger a genuine failure and compare detection time, alert clarity, and false-alarm rate before any money changes hands.
