Free & open source · For nonprofits & event teams

Run every event from one organized home

Diony gives nonprofits and event organizers a single, structured space for every event — broken into components, tasks, budgets, and team. From first plan to final task. Free to use, and open source.

Scattered across tools

Contacts in email, budgets in Google Sheets, tasks in Slack — nothing connects to anything else.

No visibility for the team

Collaborators work blind. Organizers become the single source of truth — by necessity.

Built around how event teams actually work

1
Create your event

Spin up an event inside your organization, then break it into components — Finance, Marketing, Volunteer, and more. Each one is its own workspace.

2
Organize the work

Every component gets a kanban board, notes, a calendar, files, and resource links. Group work into activities, then break those into tasks and subtasks.

3
Track the budget

Build line-item budgets per component and detailed estimates in a built-in spreadsheet editor. Always current, always visible to the team.

4
Collaborate with control

Invite collaborators with owner, admin, or member roles — scoped right down to individual components. Mentions and notifications keep everyone in sync.

Component workspaces

Every part of an event, in its own space

  • Kanban boards per component to move work from idea to done, with drag-and-drop reordering
  • Notes, files, and resource links kept right alongside the work they belong to
  • A built-in calendar per component, plus a master calendar across the whole event
  • Reusable templates so a proven component setup launches the next event in seconds

Budgets & estimates

Know where every dollar is going

  • Line-item budgets for each component, rolling up to a clear view of the whole event
  • A spreadsheet estimate editor built in — columns, sections, and cells, no exporting to Excel
  • Clients CRM and a shared file library to keep contacts and documents in one place
  • My Work — a personal task table with custom columns that never touches the shared data

"We were running three events out of one shared spreadsheet. Diony gave every component its own board and budget — and let me invite volunteers without handing over the whole org."
