# Plan Features Comparison

Find the right Basin plan for your needs. This page provides a detailed comparison of features across all Basin plans.

!!! tip "Current Pricing"
    For up-to-date pricing information, visit [usebasin.com/pricing](https://usebasin.com/pricing).

!!! note "Submission Limits"
    **Paid plans:** If you exceed your monthly submission limit, submissions continue uninterrupted and overages are billed automatically based on volume tiers. See [Overage Pricing](#overage-pricing) below.

    **Free plan:** You'll receive email warnings as you approach your limit.

    **All plans:** Limits reset monthly. Spam submissions never count toward your limit.

## Basin Forms, Chat, and Sites

- **Basin Forms** is the form backend, with endpoints for your own HTML, Form Studio, Basin JS, submissions, spam filtering, email, and integrations.
- **Basin Chat** is an embeddable AI chat widget. Access is included with paid plans; AI usage is billed separately.
- **Basin Sites** are AI-generated websites hosted by Basin with built-in Basin forms.

!!! info "Basin-hosted AI Sites"
    The Basin Sites limit applies only to AI-generated websites hosted by Basin. It does not limit how many externally hosted websites can use Basin form endpoints.

    Domain setup differs by purpose: a **custom site domain** is connected on a Basin-hosted AI Site’s page; a **custom email sending domain** is verified under the account Domains tab (DKIM / Return-Path) for outbound mail. See [Custom Email Sending Domains](email-notifications/custom-email-sending-domains.md).

### Growth Plan
**Best for:** Freelancers and teams managing multiple sites, collaborators, integrations, and autoresponses.

### Pro Plan
**Best for:** Lead generation that needs advanced spam filters, custom email delivery, AI scoring, and secure files.

### Agency Plan
**Best for:** High-volume, multi-client workflows that need multi-step forms, incomplete-submission follow-ups, and priority processing.
