Bventy

Overview

Bventy is an open-source infrastructure layer designed to structure how event organizers and vendors interact. Instead of relying on informal coordination through messaging apps and manual negotiation, bventy introduces a structured quote lifecycle, role-isolated dashboards, and controlled communication flows. It transforms fragmented vendor discovery into a transparent, auditable workflow system built with a focus on openness, visibility, and community trust.

Bventy enables organizers to discover vendors through searchable listings and initiate structured quote requests tied directly to event details. Each interaction follows a defined lifecycle - from request to response, revision, confirmation and controlled contact unlocking, ensuring that vendor coordination remains state-driven rather than conversationally ambiguous. This structured process also allows contributors and community developers to reason about system state clearly and extend workflows in predictable ways.

The project is built as marketplace infrastructure, not just a listing platform. Architecturally, bventy implements multi-role dashboards across isolated subdomains, secure cross-subdomain authentication, structured state management for quotes, attachment-controlled negotiations, and analytics-ready data models. The frontend is organized as a turbo-based multi-app workspace powering role-specific dashboards, while the backend enforces lifecycle rules, role-based access control, reproducible behavior, and data integrity in an open codebase.

As an open-source project, bventy focuses on making event marketplace coordination transparent, extensible, and auditable by design. It is purpose-built for the events ecosystem, including community events, tech gatherings, business functions, and small-scale private events, while maintaining a clean, modular architecture that allows communities to deploy and evolve it openly. The backend and frontend both are licensed under AGPL, ensuring that improvements to the core coordination engine remain open and auditable by the wider community.

Architecture

• Multi-role dashboards (organizer, vendor, admin)

• Isolated subdomain architecture

• Structured quote state machine

• Controlled contact unlocking

• Attachment-managed negotiations

• Analytics-ready relational data models

• Cross-subdomain secure authentication

The system is designed to prioritize clarity of workflow, state integrity, and role-based isolation.
