FreeBusy

FreeBusy is a scheduling service that draws availability from multiple calendars and helps individuals and teams arrange meetings. It is best for people who coordinate across separate work and personal calendars or need shared team booking. Its strongest case is the combination of calendar breadth, booking controls and team tools; the main trade-off is that several protections and controls are reserved for Enterprise.

Overview

FreeBusy combines availability across work, personal and school calendars while keeping those calendars separate. That makes it a practical choice for people whose commitments span multiple accounts, and for teams that need to find a suitable colleague rather than simply offer one person’s open slots. Website widgets, a Pick-a-Time button and event-update webhooks also extend scheduling to external visitors.

The product’s depth is split across plans: Personal covers individual bookings and meeting polls, while availability preferences and conferencing integrations begin with Professional. Team scheduling requires Business. Enterprise adds compliance and procurement features, including SAML single sign-on, VPN connectivity and HSM credential protection. FreeBusy says it does not store calendar data, but it does store credentials for some password-based calendar connections.

Key features

Calendar availability and booking controls

Calendar connections include Google Calendar, Office 365 and Outlook, Exchange, iCloud, Salesforce Calendar, Yahoo, Zimbra, Zoho and Amazon WorkMail. Users can set preferences to avoid back-to-back meetings and meetings that are too soon or too far in the future. Those controls matter to anyone offering booking times while trying to preserve breaks or avoid dates outside a useful planning window; they require Professional rather than the free plan.

FreeBusy supports appointment bookings and meeting polls on Personal. Professional adds web conferencing and Outlook and Google add-ons, which reduce the need to shift between scheduling and meeting setup. The conferencing integrations include Zoom, Microsoft Teams, RingCentral, GoToMeeting, Webex, Skype for Business, BlueJeans, Google Meet, join.me and FreeConferenceCall.

Team and website scheduling

Business adds a team scheduling assistant, forms and questionnaires, reminders and follow-ups. Teams can pool availability, identify available teammates, assign delegates and add co-organizers. Group events, round-robin routing and team booking pages support a range of coordination patterns, from a shared meeting to distributing incoming bookings. These are useful for recruiting, sales and customer assistance teams, but they are not included in the lower individual plans.

For public-facing booking, embeddable widgets and a Pick-a-Time button let visitors choose a time, while webhooks send event updates for scheduling, rescheduling or cancellation. Other integrations include a Chrome extension, an Outlook add-in, Salesforce, Greenhouse, HubSpot, Intercom and Zapier, broadening its usefulness for recruiting and customer-facing workflows.

Security and privacy

FreeBusy says calendar credentials are encrypted with AES 256-bit keys wrapped by RSA 4096-bit keys, and that data is encrypted in transit and at rest. It states that it is GDPR compliant and offers a Data Processing Addendum. Enterprise customers can request dedicated encryption keys managed with Azure Key Vault and held in FIPS 140-2 Level 2 certified HSMs. That is a meaningful option for organizations with stricter requirements, but HSM credential protection, SAML single sign-on and VPN connectivity sit behind Enterprise rather than the standard team plan.

Pricing

FreeBusy uses a freemium model, with a 14-day trial for paid plans. The plan split is consequential: free covers basic individual scheduling, the lower paid tiers add controls and team work, and enterprise requirements call for custom pricing.

Business charges per registered user and is the point at which team scheduling, forms and follow-ups arrive. Enterprise is the route for the listed identity, network and dedicated-key protections; organizations should weigh that plan boundary against their security needs.

Platforms

FreeBusy supports API, extension, macOS, web and Windows. The mix covers browser-based scheduling and desktop environments, with an API for integrations; no mobile platform is included in its stated platform set.

Who it's for

FreeBusy is a strong fit for consultants and freelancers managing separate calendars, executive assistants coordinating schedules, and recruiting, sales, marketing or customer-assistance teams that need shared availability and booking workflows. Enterprise subsidiaries are also among its intended use cases, particularly where delegates, compliance or dedicated security controls matter.

It is less suitable for someone who only needs basic individual booking and wants availability preferences without paying, or for a team that requires SAML, VPN connectivity or HSM protection but cannot use a custom-priced Enterprise plan.

Pros and cons

Broad calendar coverage: Connections span major workplace and personal calendar services, useful when a person’s availability is split across accounts.

Useful scheduling controls: Preferences can keep back-to-back or poorly timed meetings off the calendar, though they begin with Professional.

Team and external booking tools: Pooled availability, delegates, round-robin routing, widgets and webhooks support more than one-to-one scheduling, but team features require Business.

Security features have a plan boundary: Encryption and GDPR-related commitments are stated, while SAML, VPN and HSM protections are Enterprise features.

Credential handling needs consideration: FreeBusy says it does not store calendar data but stores credentials for some password-based connections, a distinction security-conscious buyers should account for.

Seat-based team pricing: Business is priced per registered user, so a team’s total depends on its seats rather than a single flat subscription.

Verdict

Choose FreeBusy if your scheduling spans multiple calendars and you need team availability, delegates or public booking tools in the same service. Its calendar coverage and progression from individual booking to team workflows are the main reasons to choose it. Look elsewhere if you need those controls on a free plan, or if Enterprise-only security requirements make its custom-priced top tier necessary.
