Freelancer Stack
Toggl
Stacklite is a calm workspace for solo freelancers tired of juggling 6 different tools just to send one invoice.
Contracts, invoices, time tracking, and client management โ all in one place. Free forever.
The Problem
The average freelancer uses 4-7 apps just to run their business. Notion for notes. Toggl for time. Google Docs for contracts. PayPal for invoices. A spreadsheet for clients.
The result? Fragmented, anxiety-inducing admin work that eats into the actual work you freelance to do.
And before you can try most tools that claim to solve this? A sign-up wall. Email. Password. Verify. Choose a plan. By the time you're in, you've forgotten why you came.
The Solution
Guest mode. Open Stacklite and start working immediately. No email. No password. No friction. Your data saves locally. Create an account later if you want โ or don't.
Core Features
Pricing
Free. Not a free trial. Not a free tier. Free forever.
Solo freelancers shouldn't pay a subscription tax just to manage their own business.

Stacklite.live's answer:
Guest mode. No sign-up wall, no email verification, no account required. You land on the workspace and start working immediately. Contracts, invoices, time tracking, and client management all connect to each other automatically. Built for solo freelancers specifically โ not a stripped-down agency tool.
Stacklite.live's answer:
Three reasons. First, it's free โ not a free trial, not a free tier, free forever. Second, guest mode means zero friction to start. Third, it's calm by design โ no bloated dashboards, no complex workflows, no weeks of setup. Bonsai costs $19-49/month. HoneyBook doubled their pricing in 2025. Stacklite costs nothing and works in 30 seconds.
Stacklite.live's answer:
Built by a product designer who got tired of switching between 6 different apps just to invoice one client. Toggl for hours, Google Docs for contracts, PayPal for invoices, Notion for client notes. One day the context switching got too painful. So I built one calm workspace that does all of it โ and made it free because freelancers shouldn't pay a subscription tax just to manage their own business.
Stacklite.live's answer:
Modern web technologies optimized for speed, reliability, and a seamless guest-to-account experience. Built as a web application accessible from any browser without installation.
Stacklite.live's answer:
Solo freelancers โ designers, developers, writers, photographers, and consultants managing 3-15 active clients. People who bill on project or retainer basis and spend too much time on admin instead of actual work. Not agencies, not teams, not enterprise.
