In their own words
Float
Float is resource planning software that shows who is working on what, team availability, utilization, delivery, and project margins. Scheduling displays roles and experience for capacity planning, while project planning supports prices, budgets, roles, timeline baselines, and AI-assisted staffing. Reports cover capacity, utilization, actuals, margin, and budget burn. The API works with team data and project workflows, and listed integrations include Aprimo, Asana, Basecamp, Claude via Float MCP beta, ClickUp, Google Calendar, HubSpot, Jira, and Karbon. Calendar sync and recurring tasks are supported, with calendar listed as a task view. iOS and Android apps let staff check schedules, add time off, and log hours. Starter costs $7 a month per scheduled person and includes scheduling, capacity and time-off management, project scoping, API, and integrations access. Pro costs $12 a month per scheduled person and adds time tracking, AI people experience profiles, multi-currency rate cards, cost estimation, advanced reporting, SSO, and domain restrictions. A 30-day Pro trial requires no credit card.
STACK
STACK is project software for working with plan pages, measurements and cost estimation. Its Free plan supports one active project per month, up to 300 plan pages, 50 measurements per project and one viewer seat.

It is available on Android, iOS, web and Windows. The company was founded in 2011 and is headquartered in Cincinnati, Ohio, USA. The listed plan details make the free tier’s project, page, measurement and seat allowances explicit; the two paid tiers specify the same unlimited allowances for those categories.
