One toolbox.
One whole workflow.

A network that crawls, a disk in the red, files you can't send, a token bill that overshot, documents you can't find, servers you can't reach, a Wi-Fi password nobody remembers — there is a plugin for each. 100% local, and the library keeps growing.

NETWORK BOOST

Network Boost

WHEN YOU NEED IT

GitHub clones hang, Docker pulls stall, TikTok and overseas SaaS dashboards won't load — and you don't want domestic sites taking the detour.

One click takes over the system connection: overseas traffic rides the fast lane while domestic domains stay on the direct-connect whitelist at full speed.

  • System-level takeover — no manual config
  • Direct whitelist keeps local sites fast
  • Toggle anytime; closing restores everything

DISK CLEAN

Disk Clean

WHEN YOU NEED IT

C: is in the red — WeChat, WeCom and DingTalk caches quietly ate tens of GB. Worse, contracts, quotes and ID photos received in chat have sat on disk for years: wasted space and a leak risk.

Daily Clean sweeps the usual junk; Deep Clean goes further into browser caches, thumbnails, update packages, memory dumps and the recycle bin — and clears documents retained by chat apps along the way, freeing space and cutting leak exposure. Reclaimable size is shown per item.

  • Daily / deep modes — see reclaimable size first
  • IM and browser caches, temp dirs, logs, thumbnails, update packages, dumps, recycle bin
  • Clears files retained by chat apps — less leak exposure

FILE LOCKER

File Locker

WHEN YOU NEED IT

You need to send a multi-GB asset bundle: cloud drives throttle, email caps the attachment, chat tools recompress it — and once it goes out through a chat app it leaves a trace in the group, searchable and traceable forever.

Drag in files or a whole folder; it packs and encrypts locally, then hands you a download link and a password. No chat app is involved, so there is no group trace and nothing to trace back — and it expires on its own.

  • Drag and drop · up to 5 GB per bundle
  • Link and password sent separately
  • No chat app involved — no group trace, nothing to trace back
  • Auto-deleted after 24 hours

TOKEN MONITOR

Token Monitor

WHEN YOU NEED IT

You use Cursor, Codex, Copilot and Kimi all month, then find the bill overshot — with no idea which model burned it.

Aggregates every coding assistant's usage locally: reconcile by model, drill into sessions, and watch daily and monthly trends — you see the spike before the invoice does.

  • Cursor / Codex / Copilot / Kimi and more
  • Breakdown by model and by date
  • Data stays local, history retrievable

FILE SWEEP

File Sweep

WHEN YOU NEED IT

Before an offboarding handover or a compliance audit, you need to know how many contracts, quotes and customer lists are still sitting on this machine — Office documents scattered across terabytes are the easiest leak to miss.

Define which extensions to scan and which directories to skip, surface every Office document scattered across the disk, sort by size, then locate or delete them in one pass — cutting the leak risk from retained files to a minimum.

  • Custom extensions and skip-directories
  • Whole-disk scan · Office docs listed live, sorted by size
  • Reveal or delete in place — clear retained documents in one pass

SSH TERMINAL

SSH Terminal

WHEN YOU NEED IT

Overseas VPS hosts keep failing to connect — timeouts, drops, stalls at auth — and every session also means digging through notes for the address and opening another window.

Group hosts by project and double-click to connect. Sessions can ride the boost channel, which is what fixes unreachable or unstable overseas VPS, and parallel tabs keep your work separate.

  • Host groups · double-click to connect
  • Parallel tabs · drop a file to upload it
  • Optional boost channel — fixes unreachable overseas VPS

WIFI PASSWORDS

Wi-Fi Passwords

WHEN YOU NEED IT

Only this laptop ever joined the home and office Wi-Fi — now a new phone, a guest or a replacement machine needs it, and nobody remembers the password.

Lists every wireless network saved on this machine with its password in one click. Copy to clipboard and paste it over — no need to read the sticker on the router.

  • Every saved network, listed at once
  • One-click copy, paste it anywhere
  • Read locally — nothing is uploaded

FAQ // FAQ

ZStudio, in a few answers

The short version: free, local, portable. Details below.

Is ZStudio free?

Yes — free for personal use. Download the portable build installer (8.7 MB, v1.1.7) from zbstream.com and all 7 plugins are included. No signup, no installation.

Does my data leave my computer?

All plugins run locally: disk cleanup, file scanning, token statistics and WiFi password reading never upload anything. The one exception is File Locker sharing — it creates an encrypted download link that expires and is deleted automatically after 24 hours.

Which systems are supported?

Windows 10 / 11 (64-bit). The portable build runs without installation — unzip and go, and it fits on a USB stick.

Which plugins are included?

Seven today: Network Boost, Disk Cleanup, File Locker, Token Watch, Full-disk File Cleanup, SSH Terminal and WiFi Password Viewer. More plugins are added continuously, all in one package.

Is there an English interface?

Yes. The UI is bilingual (Chinese / English), auto-selected from your browser language on first visit, and you can switch manually — the choice is remembered.

Will Network Boost slow down domestic (China) sites?

No. Boosting only takes over traffic to overseas resources; domestic domains stay on a direct-connection whitelist at full speed. Toggle it anytime — quitting restores your original network settings.

Which AI coding tools does Token Watch support?

Cursor, Codex, Copilot, Kimi and other mainstream AI coding assistants. Usage and cost are broken down by model and by date, and all data stays local for later review.

How do I download and update?

Grab the latest build from zbstream.com and install over the old one — local settings are kept. Downloads come with a SHA-256 checksum.
