Taiga is the open-source agile project-management platform operated by Kaleidos, a Madrid-based Spanish software cooperative that built and continues to maintain the project since 2014. The platform is positioned as the open-source Jira / Linear / Clickup alternative: Scrum sprints, Kanban boards, issue tracking, customisable dashboards, video-call integrations, and a wiki module, all under the Mozilla Public License 2.0 with the full server-side code on GitHub. Taiga is widely used in EU public administrations, universities, and open-source-friendly engineering teams.
Two deployment paths are offered. Self-hosted on the customer's own infrastructure (Hetzner / OVHcloud / Scaleway / private DC) makes the customer the sole data controller and operator, with no CLOUD Act exposure. The managed cloud at tree.taiga.io is the alternative for teams who prefer not to run the stack themselves; the managed tier runs from the Interxion MAD3 datacentre in Madrid, where Digital Realty/Interxion is only the physical colocation landlord with no logical access to customer data and no US-owned hyperscaler sits in the customer-data path, so under a customer-data-at-rest definition its CLOUD Act exposure is none. The combination of MPL-2.0 licensing and a Spanish-owned operating cooperative makes Taiga the strongest agile / Scrum entry on this directory.
Pricing for the managed cloud is at /deployment-pricing-options with freemium and paid tiers; specific monthly amounts were not captured at audit. Best fit: EU public-sector procurement, universities, open-source-aligned engineering teams, and any organisation that wants a Jira replacement under EU jurisdiction and AGPL-style open governance.
