onionwright vs Multilogin
They are sold in the same market and solve different problems. Multilogin isolates identities so a person managing many accounts does not look like one device. onionwright makes automated input look human. If a script is doing the clicking, isolation is not the part that gets you flagged — the clicking is.
Side by side
| Multilogin | onionwright | |
|---|---|---|
| What it is | A profile manager — many isolated browser identities, each with its own fingerprint, cookies and storage | A patched browser plus a humanized-input layer — one identity that behaves like a person |
| Who drives it | A human, clicking through accounts one at a time | An AI agent or script, running a session unattended |
| The problem it solves | Account linkage — stopping two accounts from looking like the same device | Automation detection — stopping a session from looking like a machine |
| Behaviour / input | Whatever drives it. A human supplies human motion; a script driving Multilogin supplies none | Human motor timing — minimum-jerk paths, keystroke intervals from a biometrics dataset, events trusted over CDP |
| isTrusted on synthetic events | Not addressed — a script's el.click() is still untrusted inside any profile | Events are dispatched over CDP, so they are trusted |
| Pricing | Per profile — roughly $7 to $570 a month by profile count | Per browser-hour — $0.10, billed from usage, not seats |
| Where it runs | Their cloud, or a local app managing profiles | Your own machine, so a real host supplies a coherent fingerprint for free |
When Multilogin is the right choice
If a person is doing the work — logging into thirty accounts by hand, keeping them from being linked — Multilogin is built for exactly that and does it well. A profile manager is the correct tool when the operator is human and the risk is linkage.
It stops being enough the moment a script takes over the clicking. An automated session inside a perfectly isolated profile still moves like a machine — instant jumps, no hesitation, and every event marked untrusted the moment it is synthesised in the page. That is the layer onionwright exists for, and it is the one a profile manager does not touch.
What onionwright doesCommon questions
Is Multilogin cheaper than onionwright?
It depends on the shape of the work. Multilogin bills per profile per month (roughly $7 to $570 by profile count); onionwright bills per browser-hour at $0.10. For an agent running sessions on demand, usage billing is usually less than holding many always-on monthly profiles. For a human keeping dozens of identities warm, the per-profile model can fit better.
Can I use Multilogin for AI-agent automation?
It manages identity isolation, but it supplies no behaviour — a script driving a Multilogin profile still emits machine-perfect timing and events marked untrusted. It solves account linkage, not automation detection, so an agent inside a profile is still catchable on how it moves.
Do Multilogin and onionwright solve the same problem?
No. Multilogin stops two accounts from looking like the same device (linkage); onionwright stops a session from looking like a machine (automation detection). A team automating many accounts has both problems, and some use both together.
Running a fleet?
Many accounts, automated, is the case where both problems are real at once — isolation and behaviour. That is an enterprise conversation: concurrency, private deployment, and a coherent identity per account, sized with you.
