How to Decide

Kimai is an open-source time tracking software used by freelancers and small teams. The alternatives split into a few clear camps: Dayflow leans on automatic local‑first tracking with no cloud sync; Super Productivity blends task management with a built‑in Pomodoro timer and GitHub issue sync; Leantime adds integrated project roadmaps, Gantt‑style views and Slack notifications; worklenz offers a full‑stack project, resource and budget management suite with a self‑hosted AGPL‑3.0 community edition; SolidTime provides automatic time tracking together with invoicing templates and Stripe/PayPal payment‑gateway integrations.

When choosing a replacement for Kimai, focus on (1) the deployment model – whether you need a self‑hosted server, a desktop‑only app, or a cloud/SaaS solution, (2) the breadth of built‑in project‑management features – from simple time logs to full roadmaps, resource planning and budgeting, (3) integration depth – native connections to GitHub, Slack, payment processors or other tools you rely on, (4) the pricing tier – pure free versus freemium plans that unlock extra projects or collaboration caps, and (5) automation capabilities – automatic activity capture versus manual entry and invoicing workflows.
