Our apps
Jira Apps by Addonix
Four Atlassian Marketplace apps built on 20+ years of Jira expertise and trusted by over 200 companies worldwide. Plan across projects, turn issues into actionable checklists, connect work with JQL, and personalize your Jira UI.
Every app carries the Runs on Atlassian badge, ships with a dedicated roadmap, and is backed by partner support with cloud migration assistance.
Plan Across Projects & Teams for Jira
My Calendar
One shared calendar for every Jira date. Combine Jira issues, milestones, and custom events from projects, filters, or JQL — and plan across teams, releases, and deadlines with Month, Quarter, and Timeline views.
- Unified calendar for Jira work and custom events: due dates, delivery milestones, release windows, leave, travel, and meetings in a single view.
- Timeline grouping by Assignee, Reporter, Status, Priority, Issue Type, Project, Component, or Fix Version for workload analysis and cross-project planning.
- Flexible calendar sources — Project, Filter, or JQL Query — with configurable start/end date fields, issue fields on cards, status display, and event colors.
- Custom events with all-day or time-based scheduling, participants, event types, and recurring schedules (daily, weekly, monthly, yearly, or cron).
- Quick filters: saved JQL-based toggles above the calendar grid for one-click focus on a team backlog, priority work, or a delivery stream.
- Sharing and permissions: share calendars with users, groups, or roles at Viewer, Editor, or Admin level, including private calendars.
Fast Inline ToDo Lists for Jira
My ToDo Checklist
Turn every Jira issue into a clear, actionable checklist — without sub-task overhead. Manage Definition of Done, acceptance criteria, QA steps, code reviews, approvals, and release readiness in one native issue panel.
- Rich text task management with full Atlassian Document Format support: formatting, lists, links, smart cards, @mentions, and click-to-edit inline editing.
- Status tracking with built-in To Do, In Progress, Done, and Blocked badges — plus custom checklist statuses for your own workflow stages.
- Priorities, due dates (including relative dates like +4d or 2w 3d), drag-and-drop reordering, and seven automatic sorting options.
- Progress bars and completion counters that update in real time, so teams instantly see what is done, in progress, or blocked.
- Reusable checklist templates and default checklists auto-added to new issues by issue type, labels, summary, priority, or Advanced JQL.
- Jira Automation actions and workflow validators to scale checklist governance, plus JQL search across checklist content — all dark-mode ready.
Issue Picker Field and JQL Work Panel
My Issue Linking
JQL-powered linked-issue custom fields and configurable work item panels. Connect and display Jira issues exactly the way you need — through fields, panels, and JQL functions instead of manual linking.
- Advanced Work Item Picker field: select and link issues dynamically using JQL filters, with single or multiple selection.
- Multi-context configuration: customize field and panel behavior per project or issue type without duplicating configurations.
- Configurable JQL Work Items Panel: display related items — Related Epics, Support Tickets, open bugs — in a structured layout with the columns you choose.
- JQL-based linking rules that automatically sync or filter linked items based on project, issue type, or status in real time.
- Permission-aware display: optionally show or hide issues based on user permissions.
- Lightweight report-style dashboards inside Jira issues by combining picker fields and panels.
JS, CSS and UX Extensions for Jira
My UI Toolkit
Safely inject custom JavaScript and CSS into your Jira instance. Tweak the UI, automate repetitive tasks, and add new functionality — with runtime changes that never touch Jira core files.
- Custom CSS injection: modify colors, layouts, and fonts to match your branding or improve readability.
- JavaScript enhancements: automate workflows, add shortcuts, quick-action buttons, and bulk-edit helpers directly in Jira.
- Non-destructive by design: modifications apply client-side at runtime — no backend changes, no Jira restart, no risk of breaking the instance.
- Avatars for User Picker custom fields for quick visual identification of users.
- Select2 autocomplete for select fields, matching system field behavior.
- Script Registry with ready-to-use scripts and a simple migration path from the JS Includer plugin.
