What Stackfield is

Stackfield is an all-in-one project management and team collaboration service from Stackfield, headquartered in Munich, Germany. It combines team chat, threaded discussions, audio and video conferencing, and screen sharing with project tools such as tasks, Kanban boards, timelines, portfolios, reporting, workflows, and time tracking. Channels and guest access are available. Teams can use web, Windows, macOS, iOS, Android, and the Stackfield API, with integrations for Microsoft Teams and incoming webhooks. Stackfield says data processing stays on EU servers and storage uses German data centers. It describes browser-side AES encryption with 256-bit keys and RSA with 2048-bit keys, plus BSI C5 and ISO certifications including ISO 27001. Paid plans start at €9/user/mo when billed annually; there is no free plan. A 14-day Premium-feature trial requires no credit card, although conferences initially last three minutes. Support is offered through live chat, email, phone, and a knowledge base.
