A check is up while pings arrive within its period plus grace time and goes down, with a notification, when they stop. The Business plan (USD 20 a month, 100 jobs) is offered free of charge to open-source projects and nonprofits on request. - per-object cap: the first 100 kB of the request body of each received ping is stored; the Ping-Body-Limit response header reports the limit in bytes | bytes: 100000 | source: [2] - retention: 100 log entries are kept per job on the Hobbyist plan and the oldest entry is removed when the limit is reached; a job that pings every 5 minutes is covered for about 8 hours | source: [1] | note: Paid plans keep 1000 log entries per job. The API lists at most 100 logged pings for a free account. - egress: not applicable: an inbound ping receiver; the ping log of a check is read back through the API, which returns 100 pings for free accounts and 1000 for paid accounts | metered: no | source: [3] - identity: email | detail: The login page offers Create Your Account and states that a magic login link is emailed; payment details are entered under Account Settings, Billing, when a paid plan is chosen. - interface: rest - limits: - volume-quota (binding): 20 checks per account on the Hobbyist plan [3] - retention-clamped: 100 log entries kept per check, oldest removed first [1] - request-rate: Management API: avoid more than 100 requests per minute; ping endpoints: a check pinged more than 5 times per minute may have requests ignored [3] - per-object-cap: 100 kB of ping request body stored per ping [2] - limits note: Notification credits for SMS, WhatsApp and phone calls are listed on the Business and Business Plus plans only. - binding note: The 20-check cap is reached before any rate limit by an account that monitors many jobs; the 5-pings-a-minute rule binds only a job that pings in a tight loop. - interface detail: Ping endpoints at hc-ping.com take HEAD, GET and POST requests with no key in the URL path beyond the check UUID or slug; a Management API v3 at healthchecks.io/api/v3 takes an X-Api-Key header with a project-specific read-write or read-only key. - endpoint: https://healthchecks.io/api/v3/checks/ - tooling: curl or any HTTP client against the ping URLs and the Management API, and the web dashboard. As a last resort the server is open source under the BSD 3-clause license: the user installs and runs it on a rented or free machine. - composes with: Dead man's switch for the scheduled jobs of free hosts: a cron line, a CI schedule or a serverless timer sends one HTTP request to a ping URL, and the check alerts by email or chat when the ping stops arriving. - reliability: Pings above 5 a minute to one check are answered 200 but not recorded; an account inactive for over a year is closed 30 days after an email notice. - notes: The free plan caps the number of jobs, not the number of pings, so a small set of frequently pinging jobs fits easily; the Business plan at USD 20 a month raises the cap to 100 jobs. - evidence note: Plan limits, rate limits and the sign-up method are quoted from first-party pages. No account was opened, so whether any later step asks for a phone number is unverified: behind a sign-up. An authenticated API call from a free account would move the record to measured. - self hosted: no - evidence: - [1] 2026-11-01: the Hobbyist plan costs USD 0 a month and monitors 20 jobs with 100 log entries per job | capture: sha256:beba7838c3d9291779324073380b01187a5f6954dd278017d5238673c3861143 | quote: ## Hobbyist $0 / month - Monitor 20 jobs - 100 log entries per job - [1] 2026-11-01: the Business plan costs USD 20 a month with 100 jobs, 1000 log entries per job and SMS, WhatsApp and phone call credits | capture: sha256:beba7838c3d9291779324073380b01187a5f6954dd278017d5238673c3861143 | quote: ## Business $20 / month - Monitor 100 jobs - 1000 log entries per job - 50 SMS & WhatsApp credits - 20 phone call credits - [4] 2026-11-01: a check goes down, with a notification, when pings stop arriving within the period plus grace time | capture: sha256:a3ccfe4d843188f5ec1fd3f37413d00202b218be796c8f3d65b8c4b96049432a | quote: Down.
