Run your freelance business from one file.
Clients, projects, invoices and your real revenue — in one clean dashboard. No account, no subscription, no cloud. Open it in your browser and get to work.
Your business, scattered everywhere
If your clients live in your inbox, your projects in your head, and your invoices in three different apps, you never actually know where you stand.
You scroll through emails trying to remember which invoice got paid.
Projects blur together and deadlines sneak up.
No single number tells you what you collected versus what's pending.
Everything in one place
Studio OS is deliberately small and fast. Four modules, one file, zero setup.
Collected, outstanding and active pipeline — updated live.
A lightweight CRM: contacts, company, rate, notes.
Value, status and due date for every job.
Issue, track and mark Paid / Sent / Draft. Totals auto-calc.
How it works
One HTML file. Double-click it. It runs in any modern browser, online or off.
Drop in a client, a project, an invoice. The dashboard fills in instantly.
Export a backup or CSV any time. Your data stays on your device.
