General Bots Calendar

General Bots Calendar is a self-hosted team calendar with chat-based scheduling, task visibility, and an API for event management. It best suits teams prepared to run software on their own infrastructure. Its unlimited-user, no-per-user-fee model is compelling, but customers take on deployment and hosting.

Overview

Day, week, month, and agenda views handle everyday planning, with mini-calendar navigation and keyboard shortcuts for moving through dates. Users can request meetings, calls, or reminders in natural language, and invitations are sent automatically. That makes scheduling more direct than entering each event through forms, while the self-hosted model makes infrastructure upkeep part of the choice.

The product is part of General Bots, founded in 2017 and headquartered in Rio de Janeiro, Brazil. Its source is available under AGPLv3, and it is deployed as a self-contained Docker setup on a virtual machine or bare metal, with the suite's apps pre-installed. The desktop launcher provides access without a separate install or signup.

Key features

Scheduling and availability

Calendar supports meetings, calls, all-day and recurring events, and personal reminders with lead time. An availability endpoint can suggest open booking slots, allowing teams to connect scheduling to other workflows through the API. These capabilities make it useful for coordinating varied event types; teams wanting a hosted calendar instead will need another service.

Tasks, APIs, and sync

Tasks with due dates appear alongside events, and completing one marks it done on the calendar too. That keeps deadlines visible in the schedule, though it is a focused task connection rather than a substitute for a full project-management system.

REST endpoints support creating, reading, updating, and deleting events, as well as checking free/busy availability. Calendar also syncs with other apps and names CalDAV servers as a calendar-service integration, giving teams an integration path beyond its own interface.

Pricing

The Self-Hosted plan costs nothing. It includes unlimited users and operations, self-hosting on the customer's infrastructure, and AGPLv3 source, with no per-user licensing fees. That is a strong fit for teams able to provide and maintain their own hosting, particularly those with many users; the price does not remove the work of running the deployment.

There is no cheaper tier to trade down to: this is the free self-hosted offering. The product page also links to a Talk to Us contact option.

Platforms

General Bots Calendar supports API, Linux, macOS, self-hosted, web, and Windows. The stated supported-platform category is web, and desktop-launcher access comes through the General Bots suite without a separate install or signup.

Who it's for

Choose it if your team wants natural-language scheduling, event and task visibility, and API access while keeping calendar data on hardware it owns. It is less suitable for teams that do not want to deploy and operate a Docker-based service, or that prefer a hosted calendar.

Pros and cons

• Pros: Unlimited users and operations with no per-user licensing fees make the free plan scalable without seat charges.
• Pros: Chat scheduling, booking availability, and REST event operations serve both direct calendar use and integrated workflows.
• Pros: Self-hosting and AGPLv3 source support control over where data runs and access to the source.
• Cons: Customers must host the deployment on their own infrastructure, so it is not a hosted-service option.
• Cons: Task support centers on due dates appearing in the calendar and completion syncing back, not broad project management.

Verdict

General Bots Calendar is a good choice for teams that want scheduling, task deadlines, and API-based event management while retaining control of their data and infrastructure. The free plan's unlimited users and operations are its clearest advantage. Look elsewhere if you want a hosted service or do not want to take responsibility for deployment.
