Offers
Free Plan (50 monitors, forever free) high confidence
Official pricing page (fetched 2026-10-22): $0/month. 50 monitors; 5-minute check interval; HTTP/website, keyword, ping, port, API, UDP, dependency, location-specific, slow-response, DNS and SSL/domain-expiry monitor types; 1 basic status page (UptimeRobot subdomain, no custom domain/white-label); 3-month data retention; only 5 integrations allowed; no login seats, no notify seats; monthly email reports only first 3 months; no SMS/voice credits included (pay-per-pack, from $3 one-time for 10). No credit card required. Free for any use including commercial and business use under current terms.
Eligibility
Everyone: no .edu email, no startup age/funding cap, no region limit, no credit card. Commercial use allowed again per terms updated 2026-05-26; governed by a Fair Use Policy (no coordinated multi-account circumvention, no automation patterns straining shared infrastructure; enforcement discretionary).
How to claim
Register free at uptimerobot.com (pricing page 'Register now'); no credit card. Paid upgrades optional via 'Upgrade' in header/My Settings.
Expiry
No expiry — permanent free tier, renews indefinitely while within 50-monitor/5-min limits and Fair Use Policy. Downgrade/lapse of any paid plan reverts account to this plan and pauses monitors above the 50 limit.
Gotchas
2024-12-01 ToS had banned commercial use; that ban was reversed in the 2026-05-26 terms update (stale third-party guides still claim it). SMS/voice alerts are NOT free: one-time credit packs ($3/10 msg, $15/100, ...; Russia/Az/BD etc. consume 2-5 credits per SMS, voice calls 2 each). 3-month log retention is short; API is rate-limited (~10 req/min per third-party reporting — verify in-app). No maintenance windows, no Slack/Webhook/PagerDuty on free (5 integrations only).
Sponsored Plan for non-profits, charities & open-source projects medium confidence
Official help article (updated 2026-09-28): non-profit, charity, or open-source projects that outgrow the free plan 'may be eligible for a Sponsored Plan that provides premium features at no cost'. No published spec of included features or monitor counts; case-by-case via support.
Eligibility
Representatives of non-profits, charities, or open-source projects needing more than the free plan. Not a student/startup program — no .edu requirement mentioned, no funding-cap criteria published. Adjacent, not aimed at for-profit startups.
How to claim
Contact the UptimeRobot support team; they state eligibility criteria and application steps on request. No public application form found on official pages.
Expiry
Not published; treated as a review-based sponsorship, so renewal/duration unknown — confirm terms in writing when granted.
Gotchas
Eligibility and scope are opaque until you apply; 'premium features at no cost' is not itemized, so verify which plan (Solo/Team/Scale equivalents) is covered. For-profits/startups are not the stated audience — a funded startup would need the free plan or paid plans.
AI-agent sign-up flow (free account, no signup form) medium confidence
Announced in official blog (updated 2026-07-29): an AI agent can create the free account and a live HTTPS monitor with no traditional registration. Agent submits site URL + user's email (after solving a proof-of-work anti-abuse puzzle); user clicks 'Activate' in the confirmation email; monitor goes live on the free plan (50 monitors, 5-min checks, 1 public status page, 5 integrations incl. Discord/Google Chat/Pushover/Pushbullet/Splunk, iOS/Android apps).
Eligibility
Same as the Free Plan — any use including commercial; email required; no credit card, no .edu, no region limit. Available via any agent that follows UptimeRobot's llms.txt / agent-skills instructions.
How to claim
Ask your agent: "Set up uptime monitoring for <site> with UptimeRobot's agent flow. My email is <email>"; then click Activate in the inbox confirmation. Nothing is created until you confirm.
Expiry
Same as Free Plan — permanent, no trial clock; subject to the 50-monitor/5-min Fair Use limits.
Gotchas
This is an onboarding channel, not extra quota: it yields the identical free-plan limits, so don't double-count it against the main Free Plan finding. Confirmation email must be opened or the monitor never starts.
No dedicated education license, student program, or startup program medium confidence
Verified against the official help article (2026-09-28): there is no education license, .edu-verified student offer, startup trial credit, or startup accelerator partnership. Students and startups are simply listed as audiences for whom the standard Free Plan fits ('educational institutions monitoring course platforms and student resources', 'startups and side projects'). The only beyond-free cost-free offer is the non-profit/OSS Sponsored Plan above. Web-search budget was exhausted mid-research; no additional official program page was located on uptimerobot.com or help.uptimerobot.com.
Eligibility
n/a — absence finding. Free Plan requires no .edu; startups require no funding-age criteria because no separate program exists.
How to claim
Students/startups claim the standard Free Plan (register free at uptimerobot.com, no credit card). Nothing extra to apply for.
Expiry
n/a.
Gotchas
Do not assume a student discount exists elsewhere; any 'education' framing on third-party sites is marketing, not a UptimeRobot program.
1) Commercial-use ban on the Free Plan (introduced in the Oct 2024 ToS update, enforced 2024-12-01) was REVERSED in the terms updated 2026-05-26 and re-confirmed by the 2026-06-15 help article: the free plan is again explicitly available for business/commercial use. Stale third-party content (e.g., Spork's 2026-03 and StillUp's 2026-05 write-ups) still claims the ban is in force. 2) Paid lineup was re-priced and restructured in 2026: earlier articles cite Solo $7-8/mo and Team $29-34/mo; current US pricing is Solo $13/mo ($12 annual), Team $46/mo ($39 annual), new 15-second Scale plan $98/mo ($79 annual) with 200/500-monitor tiers, Enterprise custom — EU visitors see euro pricing (e.g., Solo €10/mo). Team moved to 30-second checks. 3) No student/education or startup-specific program ever existed to sunset; the only cost-free non-standard offer (Sponsored Plan for non-profits/OSS) remains active with no announced change. 4) New 2026: AI-agent sign-up channel for free accounts (proof-of-work + email confirmation gates). Note: a session-wide web-search budget was exhausted partway through this research, so absence claims rest on the official pricing + help pages fetched today plus full-text search snippets.
