Browser · 7 modules

One machine, hundreds of browsers that never mix

Each profile keeps its own cookies, proxy, extensions and fingerprint. The rest is about controlling them fast.

Profiles + proxyAvailable

Every profile is a separate browser

Cookies, sign-ins, site storage and extensions of one profile never leak into another. Each profile goes through its own proxy.

The proxy line shows carrier, IP and latency from the latest check
A broken proxy turns red right on the row, with the reason
HTTP, HTTPS, SOCKS4, SOCKS5, with or without a password

Data and leads · 3 modules

Know which groups are worth posting in, and who is looking for a room

Group data stays on your machine. The app tells you which groups are still active and which posts are real guests.

NEXTCORE GROUPCRAWLAvailable

A local group library, with numbers to choose by

Every group you visit is saved with its member count, posting rhythm and the role each profile has in it.

Filter by region, size and posting rhythm
See which profile is admin, moderator or member
Export lists for posting scripts

Automation · 2 modules

Scripts do the repetitive work, you review the results

Scripts run across many profiles at once, paced like a real person, and stop to wait for you where a decision is needed.

NEXTCORE AUTOMATIONSIn NextCore plan

Scripts that run across many profiles

Chain steps like opening profiles, posting and logging results into one script. Run it on a schedule or by hand and watch where each step is.

Auto-post to many groups, spaced 4–9 minutes apart
Images and text rotate through a list
Per-group results reported to NEXTCORE CRM

For developers · 3 modules

Drive it with scripts or with AI agents

Everything you can click in the app can be called through the Local API. It listens only on your machine, with a token.

Local API + CDPAvailable

Playwright and Puppeteer connect straight to a profile

Create and open profiles, then get a CDP port so scripts drive them like a normal browser.

Roadmap
