Keyhold vs Chaster

This is the sharpest difference, and it cuts both ways.

• Chaster free: one lock locked at a time, and up to three extensions on it.
• Keyhold free: three active locks at once, multiple keyholders per lock, and the extensions catalogue.

If you want to run a chastity lock and a bondage lock at the same time, Keyhold’s free tier does that and Chaster’s asks you to pay. Our free tier is the more generous one on both counts, and we would rather it stayed that way than win an argument about it.

The concession is about depth rather than access. Chaster has spent years accumulating extensions and we have not; three of theirs may well beat the whole of ours depending on what you want to play with. More below.

Profile pictures are the other one worth knowing: on Chaster they are a Plus feature. On Keyhold they are free, and always will be.

Chaster Plus is €9.99 a month. Keyhold Plus is $9.99 a month. At current rates those are near enough identical that price should not be your deciding factor, and anyone telling you they are dramatically cheaper is rounding in their own favour.

What differs is what the free tier does before you reach that decision, which is the section above.

The community, by a distance. Chaster has years of users, thousands of community-built lock configurations, and enough people online that you can find a keyholder at three in the morning. Keyhold is new. If your reason for using a platform is that other people are already on it, that is a completely sound reason to use Chaster, and no feature list changes it.

The extension ecosystem. Years of accumulated variety — timers, games, tasks, penalties, pillories. We have an extensions system; we do not have their catalogue.

Combination image verification. A moderator checks that the photo of your combination is actually readable before you close the box. That is a thoughtful safety feature aimed at a genuinely nasty failure mode, and we do not have an equivalent.

Open documentation. Their docs are on GitHub and anyone can file a correction. That is how we sourced the numbers on this page.

Reliability scores and abandonment detection. The oldest complaint in online chastity is the keyholder who stops replying while someone is still locked. Every Keyhold profile carries a public reliability score with a published formula, and locks that go silent are detected and counted rather than left to rot in a list. We could find no documented equivalent in Chaster’s material — if they have one, tell us and this paragraph changes.

The honest limit, since this is the claim the whole page rests on: today that score measures people as wearers — whether they finish the locks they take on. Scoring keyholders on whether they show up is the next thing being built, and until it ships the badge on a keyholder’s profile tells you about their own time locked, not about their record of holding someone else’s key.

A warning when your keyholder goes quiet. If a keyholder-controlled lock sees no keyholder activity for 14 days, we tell the wearer. It does not end the lock — that stays your decision — it just makes sure you know.

A published security page. Actual algorithms, actual failure modes, and a list of what we have not done. Nobody in this niche publishes one. Read it and judge for yourself.

One-click data export. Your account, locks, tasks, verifications, posts and messages as a JSON file, from Settings, immediately. More on why that matters.

Use Chaster if you want the biggest community, the deepest catalogue of extensions, and software that has been shaken out by years of users. Those are the correct reasons and they are not small.

Use Keyhold if being left locked by someone who wandered off is the thing you actually worry about, if you want more than one lock without paying, or if you want to read how a platform handles your data before you hand it over.

Both are free to try, neither asks for a card to sign up, and running a lock on each costs you nothing but the time. That is a better way to decide than a comparison table written by either of us.

There is no automatic import — Chaster has no data-export path we could use to build one, so a migration means starting a fresh lock here rather than carrying your history across. We would rather say that plainly than let you find out after signing up.

The practical approach is to run your next lock on Keyhold rather than trying to move a lock that is currently running. Your history there stays there. If enough people want a real importer we will build one, and if Chaster ever ships an export we will support it.

Chaster’s pricing and Plus features are taken from their own Chaster Plus page, and the free-tier limits from their open-source documentation, which states that normal users have one lock at a time and three extensions.

Checked on 9 September 2026. Both are live documents and will drift. If you are reading this much later, check them rather than us — and tell us so we can correct the page.
