JustBrowser vs Nstbrowser

A side-by-side comparison of JustBrowser and Nstbrowser, 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. Nstbrowser prices by saved profiles, daily launches and team members. Their free plan holds 500 profiles and 3 team members for $0, but opens at most 30 different profiles a day before each further launch is billed; their Starter plan, $29.90/month, holds 20,000 profiles and 20 team members with 3,000 launches a day. Their page does not say whether the free plan's 3 team members include the account holder, or what a member past a plan's cap costs, so what 100 profiles with 3 teammates costs cannot be stated from it.

Nstbrowser 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.

Other pages of their own site describe the free plan differently, with up to 1,000 launches a day and unlimited team members; the pricing page's figures are the ones used here. 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. Nstbrowser runs Nstchrome, a Chromium-based kernel, which their profile documentation calls the only kernel supported. Their product page says Nstbrowser is based on Chromium and Firefox engines, but we found no Firefox-based engine named on their pages.

Where Nstbrowser Leads

Nstbrowser has a permanent free plan with 500 saved profiles, a hosted cloud browser that runs headless browsers in their cloud, a Docker image to run it on your own servers (in beta), free proxy traffic every month on paid plans, a no-code RPA builder, a built-in AI agent, and one-time profiles billed per launch. Those are Nstbrowser'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, where Nstbrowser's plans hold 3 to 100 team members and bill the launches past each plan's daily allowance. JustBrowser's Firefox profiles run real Firefox.
