Chaster vs Simply Locked

Simply Locked vs Chaster

Both Simply Locked and Chaster can manage timed chastity locks online, support keyholders, and hold a combination for a physical lockbox.

The main difference is how much complexity you want around the lock.

Chaster details on this page were last checked against Chaster’s official documentation in September 2026.

What is Chaster?

Chaster is an online chastity and keyholding app built around time-based locks.

It lets wearers create their own locks, give control to keyholders, load locks created by other people and add extensions that change how a session works.

Chaster describes its extension system very directly:

“Extensions are the core of Chaster, and allow infinite customization.”

Extensions can add games, tasks, random events and other mechanics to a lock. Chaster also has community-created locks, events and an established user community.

That makes Chaster a good fit for people who want to configure a more elaborate session.

What is Simply Locked?

Simply Locked is a minimalist online chastity locking app for consenting adults.

It is designed around a much shorter setup process.

Choose how long you want the lock to last, decide who should control it, optionally set a lockbox combination, and start.

You can use Simply Locked for:

• self-locking
• keyholder-controlled locks
• crowd-controlled locks
• chastity timers
• combination lockbox codes
• Beg attempts
• hygiene unlocks on longer locks

You do not need to create an account before starting.

Accounts are optional and are mainly useful if you want your locks available across browsers and devices.

Which app is simpler?

Simply Locked.

That is intentional.

Chaster gives you many ways to configure a session. Its extension system is one of the main reasons people use it.

Simply Locked tries to remove decisions that are not necessary to start a lock.

If all you want is a five-hour lock, for example, the basic Simply Locked flow is:

1. Choose five hours.
2. Choose who controls the lock.
3. Set your lockbox if you are using one.
4. Start the lock.

You can then use optional features while the lock is running.

The goal is not to recreate Chaster with a different interface. The goal is to provide a smaller, faster alternative for people who do not need a large extension system.

Do you need an account?

Simply Locked does not require an account to create your first lock.

Your lock can be created and stored in your browser immediately.

If you later create an account, your locks can be attached to it so you can keep access across devices.

Chaster is account-based. Its own sign-up page asks users to create an account before accessing the application.

For someone who just wants to try an online chastity timer without registering first, this is one of the biggest differences between the two apps.

How many locks can you create?

Simply Locked allows unlimited locks as part of the free core app.

Chaster’s official Plus documentation currently says that normal users can have one lock in the locked state at a time, while Chaster Plus members can create unlimited simultaneous locks.

Chaster Plus also removes the free limit on extensions. Chaster’s documentation currently states:

“Free users can add up to three extensions to their locks.”

If you regularly run several locks at once, this is therefore a meaningful difference between the two services.

Self-locking

Both Chaster and Simply Locked support self-locking.

With Simply Locked, you can choose Just lock me when creating the lock.

The release starts with a fixed time. You can then use features such as Beg, add time to your own lock, or give control to the crowd.

This works well if you mainly want a clean chastity timer without setting up a larger session.

Chaster also supports self-locks, with considerably more configuration available through its lock options and extensions.

Keyholder-controlled locks

Both apps support online keyholding.

With Simply Locked, you can create a lock controlled by another person and give them the keyholder link.

The keyholder can then control the lock remotely.

Simply Locked keeps this relationship intentionally straightforward rather than requiring a collection of extensions before the keyholder can take control.

Chaster has a more extensive keyholder system, including configurable permissions and the ability to control other Chaster members.

If you want deeper configuration around what a keyholder can and cannot change, Chaster currently offers more options.

If you want to hand control to a keyholder without configuring a larger session first, Simply Locked is the simpler option.

Crowd-controlled chastity

Simply Locked also lets you give control to a crowd.

Create a crowd lock and Simply Locked gives you a voting link that you can post on Reddit, a forum, Discord, send to friends, or share anywhere else.

Visitors can vote to keep you locked longer or show mercy by removing time.

The result changes the release time of the lock.

Chaster offers a similar concept through its Shared Links feature.

According to Chaster’s documentation, Shared Links allow visitors to add or remove time and can also require a certain number of visits before the wearer is allowed to unlock.

The difference is mostly one of product structure.

In Chaster, Shared Links are part of a larger configurable system.

In Simply Locked, crowd control is one of the main lock types and is designed to be understandable without configuring an extension stack.

Extensions and customization

This is the area where Chaster is clearly stronger.

Chaster has an extension ecosystem covering games, tasks, random events, community mechanics and connections to external services.

Its documentation describes extensions as a central part of the product, and Chaster continues to develop new ones.

Simply Locked does not try to compete on the number of configurable extensions.

Instead, a smaller number of mechanics are built directly into the lock.

For example, Simply Locked includes Beg, which lets a locked user make a timed plea for mercy. Depending on the lock, the result can reduce time, do nothing, add time, or be sent to the keyholder to decide.

Longer locks can also offer temporary hygiene unlocks, followed by a new combination when the user locks back up.

These features are intended to add something to the lock without turning lock creation into a long configuration process.

Where Simply Locked is better

Simply Locked is probably the better choice if you want:

• no account before starting
• unlimited locks
• a faster lock-creation flow
• fewer setup decisions
• straightforward self-locking
• simple keyholder control
• built-in crowd voting
• a minimal active-lock screen
• generated combination storage without a larger configuration process

Simply Locked is particularly aimed at people who like the basic idea behind online chastity locking but find themselves wanting a smaller product around it.

Where Chaster is better

Chaster is probably the better choice if you want:

• a large extension ecosystem
• extensive lock configuration
• community-created locks
• games and tasks
• community events
• combination-photo locking
• detailed keyholder permissions
• an established Chaster community

Those are areas where Chaster deliberately offers more depth. Simply Locked deliberately trades that depth for a faster, simpler locking experience.

If configuring the session is part of the fun for you, Chaster gives you far more to configure.

Is Simply Locked a replacement for Chaster?

Not necessarily.

The two apps overlap, but they are moving toward different experiences.

If you enjoy Chaster because of its extensions, community locks, games and customization, Simply Locked probably will not replace those things for you.

If you mainly use Chaster to hold a combination, run a timer, give someone control or share a lock with other people, Simply Locked may cover what you need with considerably less setup.

Some people may also use both depending on the kind of lock they want.

Is Simply Locked free?

The core Simply Locked app is free.

That includes creating locks, self-locking, keyholder locks, crowd locks and unlimited locks.

A paid Simply Locked Plus plan is planned for optional lock experiences such as:

• random releases
• hidden countdowns
• stricter lock rules
• additional Crowd difficulty levels

The intention is to keep basic locking complete without requiring Plus.

Is Chaster free?

Chaster has a free tier.

According to Chaster’s current documentation, free users can have one active locked lock at a time and can add up to three extensions to a lock.

Chaster Plus removes those limits and includes additional features and early or exclusive access to some extensions.

Because products and subscription limits can change, check Chaster’s official Plus documentation for its current limits and features.

Does Simply Locked have extensions?

No.

Simply Locked deliberately does not use an extension system.

Features such as Crowd, Beg and hygiene unlocks are designed as parts of the lock itself rather than separate extensions that need to be installed and configured.

If you want to combine many different mechanics into a highly customized session, Chaster is the stronger option.

If you would rather make fewer decisions, that is the problem Simply Locked is trying to solve.

Does Simply Locked work with a keyholder?

Yes.

You can start a lock with another person in control.

Simply Locked gives the keyholder their own way to control the lock remotely while the wearer sees their locked view.

You can read more on the Simply Locked keyholder page.

Can other people control a Simply Locked lock?

Yes.

A wearer can create a crowd-controlled lock and share its voting link.

People opening that link can vote on the release without needing to become the wearer’s permanent keyholder.

This is useful for forum posts, Reddit posts, group chats or anyone who wants a lock affected by multiple people rather than one person.

Which should you choose?

Choose Chaster if you want deep customization, extensions, community-created locks, games and a larger ecosystem around your sessions.

Choose Simply Locked if you want the important parts of an online chastity lock with less setup.

Simply Locked’s approach is deliberately narrow:

Set the time. Hand over control. Stay locked.

No account required to start. Unlimited locks. Self-locking, keyholder control and crowd voting without building an extension stack first.

Neither approach is right for everyone.

They are different answers to the same basic idea.

Try Simply Locked

If you are looking at Chaster because you want to manage a chastity lock online, but you would prefer something simpler, you can start a Simply Locked lock without creating an account.

Choose your time. Decide who is in control. Get locked.
