Mark entire days as unavailable so only genuinely open time is offered when you build an availability table.
Free Blocks tackles the tedious part of meeting planning: telling other people when you are free. Instead of writing out time ranges by hand, you connect your primary Google Calendar and Free Blocks reads your busy periods, then generates a tidy availability table you can paste into an email or share as a personal booking page. It reads the tone of the product well — the company describes it as a way to compose emails with beautiful tables that show when you are free, and it can also block off whole days when you know you are unavailable.
Beyond the core calendar sharing, Free Blocks ships as a small ecosystem: a personal booking page, a Google Workspace app available in the Workspace Marketplace, a Chrome extension and a Slack app. That means teammates and clients can see openings and grab a time without leaving the tools they already use, which is the main reason teams choose it over heavier scheduling suites.
The product positions itself as simple and approachable, targeting individuals, small teams and anyone who coordinates meetings across companies. There is a free tier — the company markets it heavily with "try us out, it's completely free" — and a pricing page plus a contact-sales path for larger or team deployments. If you already live in Google Calendar and Slack, the value is mostly in removing friction rather than in advanced routing, round-robin or complex meeting-type logic.
Send a clean availability block or booking link so prospects can self-select a slot instead of trading scheduling emails.
Share your team's open windows in Slack so meetings land in times that actually work for everyone.
Put a booking page on your site or signature so new clients can book without an onboarding call.
Offer candidates a set of real openings pulled from your live calendar, cutting the rescheduling loop.
