Questions & Answers

As answered by people managing Rectangle and Kanera.

Why should a person choose your product over its competitors?

Kanera's answer:

Kanera is designed for teams that want powerful project management without the complexity and fragmentation that can come with larger work-management suites. It keeps the familiar board-and-card workflow while adding cross-project visibility, structured reporting, automations, notes, client collaboration, API and webhook access, and native MCP support for AI tools. There is also a self-hosted option with no Kanera per-seat licence fee, giving organisations greater control over their infrastructure and data.

How would you describe the primary audience of your product?

Kanera's answer:

Kanera is primarily built for ALL teams that manage multiple projects and need a clearer way to see work across them. It suits development, product, marketing, operations, support, project-delivery, sales and client-service teams, as well as organisations that need self-hosting or greater control over their infrastructure. It is particularly useful for teams that have outgrown basic Kanban boards but do not want the complexity of a heavyweight enterprise project-management platform.

What's the story behind your product?

Kanera's answer:

Kanera was built from a desire for a work-management system that stayed fast and straightforward while still giving teams the visibility and functionality they need as their projects grow. The goal was to keep the simplicity of working with boards and cards, but remove the need to jump between separate projects just to understand what is assigned, overdue, blocked or completed across a team. That grew into a broader project and work-management platform with connected workspaces, cross-project reporting, automations, notes, integrations, API access and AI connectivity through MCP. Kanera is developed and operated by Happen Software Limited in Ireland and is also source-available so organisations can inspect the code and self-host the complete product when required.

Which are the primary technologies used for building your product?

Kanera's answer:

Angular, Node.js, PostgreSQL, Socket.IO, Valkey, Docker and Docker Compose. Kanera’s self-hosted deployment includes the web application, API and real-time services, worker processes, PostgreSQL database, Valkey cache, public API, MCP server and nginx-based web tier.

Who are some of the biggest customers of your product?

Kanera's answer:

Kanera is still in its early commercial stage, and we do not currently publish customer names publicly.

What makes your product unique?

Kanera's answer:

Kanera combines familiar project boards with cross-project visibility and a clear record of who changed what—including your AI agents.

Keep boards independent or group them in workspaces with shared workflows, labels, custom fields, templates, and automations. My Cards, Team Cards, Team overview, and a ranked Up next queue bring priorities together across projects, while Timeline/Gantt planning and dependency maps show what is blocked and what can move next.

Accountability stays alongside the work. Timestamped activity and description diffs help explain changes. OAuth-connected AI agents are clearly identified, and live agent runs show their progress, when they need input, and their outcomes.

Bring the assistant you already use—such as Claude, ChatGPT, Codex, or Cursor—through MCP, the CLI, or API. Kanera does not require a separate Kanera AI subscription; any costs from your AI provider remain separate.

Choose managed cloud hosting or self-host the same Pro feature set with Docker Compose, with no Kanera licence or per-seat fee for self-hosting.
