JustBrowser vs Undetectable

A side-by-side comparison of JustBrowser and Undetectable, two multi-account browsers: what a team pays on each, and how their features and engines differ.

Pricing

JustBrowser is one price — $9.99/month, or $99.99/year — with unlimited profiles and unlimited teammates. Undetectable prices by plan rather than by profile: every paid plan keeps unlimited profiles on the computer where they were made, and a set number in their cloud, the profiles that sync between devices and that a team works on. Their Base plan, around $49/month, is enough for 100 profiles on one computer, with 50 cloud profiles and one user, and cannot add users. A team means their Professional plan at around $99/month: 100 cloud profiles and 2 users, the account owner one of them, with each further user $20/month. So for 100 profiles and 3 teammates, 4 users of whom 2 are extra, the comparison is roughly $139/month against our $9.99/month.

Undetectable figures read from their pricing page on 5 November 2026. Monthly billing; they also advertise a lower annual rate. Prices change — check theirs before deciding.

Their pricing page opens on its yearly prices, 30% lower; these are the monthly ones. Their documentation says users can be added to Base, but their pricing page says they cannot, and its figures are the ones used here. Undetectable also has a free plan with up to 5 cloud profiles and one user, without local profiles or the API. JustBrowser gives you 7 days of the full product to try, with a card on file so nothing stops when the trial ends.

Browser Engine

JustBrowser uses a custom Chromium build, patched at the C++ source level and rebuilt as upstream Chromium moves, and runs Firefox profiles in real Firefox. Undetectable's default engine is its own Chromium-based browser, on Chromium core 155 since October 2026; an older in-house engine, WebEngine, remains, deprecated, with no extensions and no API. Their documentation names those two engines and no Firefox-based one.

Where Undetectable Leads

Undetectable has a free plan, installers for Intel Macs as well as Apple Silicon ones, an open-source MCP server for AI clients such as Claude, Codex, Gemini and Cursor, a local API that also acts on the page (opening addresses, clicking, filling in fields, running scripts, reading the page and taking screenshots), a synchronizer that repeats actions across several profiles at once, team roles and groups set with more than 33 access parameters, with session tracking and action logs, private cloud storage on your own server on their Custom plan, a converter that moves profiles and their cookies from Dolphin Anty, AdsPower, GoLogin, Multilogin, Octo Browser, Chrome or Firefox, and payment by card, e-wallet or cryptocurrency. Those are Undetectable's descriptions of their product; we have not tested them.

Where JustBrowser Leads

JustBrowser is one flat price with unlimited profiles and free team seats, and every profile can sync to your other computers with no storage cap, where Undetectable's local profiles stay on the computer where they were made and its cloud profiles are capped by plan. Undetectable keeps teams to its Professional plan and up and charges for each user past those a plan includes. The REST API comes with JustBrowser's one plan, where Undetectable keeps it off its free plan, and JustBrowser's Firefox profiles run real Firefox.
