Looking for a Chaster alternative?

Chaster is very good at what it was built for. It runs time-based locks: the key goes in a lockbox with a code you do not know, Chaster holds the code until the time is up, and a keyholder can change how long it lasts. Extensions such as a wheel of fortune, dice, tasks and verification pictures make a lock-up into a game, and they can be combined freely.

It is also a community. You can join locks other members have made, find a keyholder online, and keep a public profile. If you want to be held by someone you have not met, or to lock yourself with others watching the timer, nothing else comes close.

For self-locking and online keyholders, Chaster is the specialist.

• The keyholder is a partner. When the keyholder is the person you live with or love, a community of strangers able to add time can feel like the wrong shape for the relationship.
• Chastity is one part of the dynamic. We could not find rules, check-ins or a journal on Chaster’s site. Couples who want the lock-up beside their tasks, rules and day-to-day often look for one app for both.
• Privacy. Profiles and locks can be public on Chaster. Some couples want something that only ever exists between the two of them.
• Games that only go one way. Wheels and dice are fun until they can only make things longer. Some couples want more control over what is on them.

• A way out that always works. Pain, numbness or a medical appointment must end a lock-up at once, whatever any timer says.
• Pauses that do not end anything. A cleaning break or a flight should be recorded as a pause, not a failure.
• Care with photos. Ask how long cage checks are kept, and who can see them.
• Both voices on the record. The person wearing the device should be able to confirm what the keyholder recorded.

Our keyholder’s guide covers the safety side in more depth.

Described from each app’s own website. Our guide to chastity apps covers the field in more detail.

ChastiSafe is non-commercial and runs in the browser, holding a combination until a lock-up ends, with timer and card locks, hygiene unlocks, tasks, games and bot keyholders. Its community lives on Discord. It is the closest in spirit to Chaster.

Chastify is built for digital keyholding and smart device control. If you own a smart lock, it is the one to look at.

Kneel is a couples’ app with chastity tracking alongside tasks, rituals and check-ins, in both app stores, where only the Dominant can release.

My Dynamic, which we make, puts chastity inside a private relationship app for two. More on it at the end.

• Who is the keyholder? A partner you live with, a partner far away, or somebody online. The answer decides most of the rest.
• Do we want the community? Some couples love other people joining in on a lock-up; others want it kept between the two of them.
• Where does the key go? In the keyholder’s pocket, in a combination lockbox, or in a smart lock. Not every app suits every one.
• What else lives in the app? If tasks, rules and check-ins already have a home you are happy with, a chastity-only app may be all you need.

Finish the lock-up you are in before you switch, rather than moving mid-way: a timer that disappears halfway through is a recipe for an argument. Write down what you liked about your Chaster setup — the extensions you used, how verification worked, how long your locks tended to run — and agree how each will work in the new app before the first lock-up there. Then talk after the first week. If October is coming, our Locktober guide is a good place to plan a month together.

In My Dynamic, a lock-up has two voices on it: the keyholder starts it and the person wearing the device confirms, optionally with a photograph. There are goals and milestones, cage checks whose photos are deleted once seen unless you both choose to keep them, cleaning breaks and pauses that do not end anything, and a wheel that can open a lock but never close one. A combination can be handed over automatically when the lock-up ends, and there is a way out that can never be switched off. Locktober is built in, and nobody outside the two of you can see any of it.

All of it sits beside the tasks, rules and check-ins of the rest of your dynamic. See the chastity side of the app.
