JustLaunchBot: how a launch is verified
The checker that visits launch URLs when their timer ends, and what it looks for.
Just Launch is a public launch board for indie developers. You commit to a launch date in public, anyone can join your waitlist while you build, and when the timer ends a bot visits your URL to check that the product is actually online. Shipped or missed, the result stays on the public record with the screenshot that decided it.
Method last updated .
When it visits
- Never before the timer ends. Not when a commitment is made, not in the last hours before the deadline.
- When the timer ends, more than once if it has to, so a momentary downtime doesn't burn anyone.
- Again some time after a successful launch, to see that the product is still there.
Before the deadline your site is yours: half-built, private or not up yet, nobody looks at it.
What counts
Something people can use or read today counts as shipped. A parked domain, an error page, an empty page or a coming-soon placeholder does not. Products on third-party platforms (App Store, Play Store…) get limited verification: the listing exists and is public.
Every result is published with the screenshot that decided it. If you think one is wrong, you can open a dispute from the launch page and a person looks at it.
Questions
What is Just Launch?
Just Launch is a public launch board for indie developers. You commit to a launch date in public, anyone can join your waitlist while you build, and when the timer ends a bot visits your URL to check that the product is actually online. Shipped or missed, the result stays on the public record with the screenshot that decided it.
How do I commit to a launch date in public?
Sign in with your X identity, add the product's URL, a name, a one-line pitch and a date, then commit. Your launch page goes live with a countdown and a waitlist anyone can join. The date can move earlier, never later.
Does Just Launch check if my site is live?
Yes, once, when it matters. When the timer ends JustLaunchBot visits your URL, takes a screenshot and decides whether there is something people can use. It never looks before the deadline.
What counts as shipped?
Something people can use or read today. A parked domain, an error, an empty page or a coming-soon placeholder does not count.
What if my site is down for a minute when the timer ends?
The bot tries more than once before it calls a result, so a brief outage doesn't decide your launch. If you think a result is wrong, you can open a dispute from the launch page.
Can I keep my product secret until launch day?
Yes, and the URL is kept for you: it is hidden on every commitment until the timer ends, so nobody can visit your site before the deadline. The board shows the site's icon and how old the domain is. You can also hide the name and the description, and the page then uses an anonymous URL. When the timer ends everything becomes public, whatever the result.
What happens if I miss the date?
The launch is marked missed on your public record, next to the ones you shipped. It can't be deleted. You can commit to a new date whenever you like.
Is it free?
Yes. Committing to a launch is free.
Does public accountability help indie hackers ship?
It removes the quiet option: the date can't slide without everyone seeing it. That's the whole mechanism. We don't publish a success rate we can't back; the board shows the real one, shipped and missed.
