What SessionBoard has that OpenSession does not
SessionBoard is a full enterprise suite. OpenSession deliberately excludes:
| Feature | Why it is excluded |
| Speaker CRM | OpenSession focuses on program management, not relationship tracking across events |
| Marketing tools | Content repurposing, transcription, and campaign tools are a separate product |
| CMS / website builder | Most organizers already have an event website |
| AI evaluators | Simple voting and scoring covers the evaluation needs of most events |
| Payment processing | Conference payment is handled by registration platforms like Accelevents |
| Integrations marketplace | OpenSession is self-hosted; you control the data directly |
| Live transcription | Out of scope for program management |
| Digital posters | Niche feature for academic conferences |
