mark yourself away.
the rotation heals itself.

flag an absence and the schedule rebalances itself with a fair swap - no manual edits, no overrides piled on overrides. cron + uptime + on-call + escalation in one tool. one flat price, never per seat.

built by a backend engineer who got tired of overrides on top of overrides - so it does the rebalancing for you.

01 · the pain

on-call breaks in the same four places

these are on-call engineers' own words, from the forums - and what oncaly does about each.

overrides on top of overrides

mark an absence once - the rota finds a fair swap automatically, no stacking.

an hour to remove someone from an escalation policy

remove someone from a policy in about 30 seconds.

cost prohibitive for our team

one flat price for the whole team - add engineers for free, never per seat.

it felt like a tool sold to CTOs, not users

built for the engineer getting paged, not the CTO buying it.
02 · how it works

mark out → the schedule heals → the alert fires → someone wakes up

one flow, one tool - from marking out to someone actually waking up.

- 01 / self-healing schedule

take a vacation. mark it once.

the rotation finds a fair swap automatically - your shifts go to whoever is carrying the least, balanced across the team. no manual overrides, no 11pm group chat.

knows when it's your day off.

syncs with google and outlook and knows public holidays for your region. if you're out, you're not in the rotation - nobody gets paged on a day off.

- 03 / reliable wake-up, included

the page that actually wakes you.

phone call plus critical-alert delivery on every plan - we call again and again until you ack, and a one-time setup makes sure the call rings through silent mode. not an add-on, not behind a paywall. you're on call because you will be called.

- 04 / all in one tool

stop gluing five products together.

cron and heartbeat monitoring, uptime checks, on-call schedule, escalation and alerting - one tool, one bill. checks fire twice from two regions before they wake anyone, so a blip never pages the team.

04 · questions

straight answers for skeptical engineers

yes - that's the point. every plan gets a phone call plus critical-alert delivery - we call again and again until you acknowledge, and a one-time setup guide makes sure the call rings through silent mode. checks fire twice, from two regions, before anyone is paged, so a single blip never wakes the team. it is never an add-on and never behind a paywall.
yes. opsgenie reaches end of life on 5 april 2027, so we're building import first - you'll be able to bring your schedules, escalation policies and monitors over in an afternoon, self-serve on every plan. cron checks from cronhub (shutting down 30 june 2026) import too. on the scale plan we'll also help with the migration hands-on.
at launch / early access: self-healing schedules with fair swaps, calendar + holiday awareness, cron/heartbeat and uptime monitoring, escalation, and reliable wake-up - these are what we're building for the first release. later: alerting on your own prometheus / graphite metrics. we label the roadmap clearly and never sell you something that doesn't exist yet.
not at launch - oncaly is hosted to start, so we can guarantee the wake-up path end to end. self-hosting is something we're listening on; tell us in the waitlist if it's a hard requirement and it'll weigh on the roadmap.
your schedules, contacts and monitoring data are yours. we use them to run your on-call and nothing else - no reselling, no training on your incident data. you can export everything, and you can delete your account and data at any time.
not publicly - oncaly is pre-launch. we're onboarding a first batch of small teams this quarter. join the waitlist and we'll reach out with early access; there's no charge and no card while you're on the list.
