Instead of Lark
Lark alternatives
Lark brings chat, calendars, document creation, and cloud storage into one workplace service. Teams can edit shared Docs during video calls, use unlimited real-time translation on Starter, and automate workflows with AnyCross. Its App Directory connects collaboration, recruitment, expense, CRM, and ERP tools, while Lark Open Platform supports custom bots, web apps, blocks, and more than 2,500 APIs. A free plan is available across web, desktop, and mobile platforms, but Starter covers 20 users, 100 GB of storage, and one-on-one meetings. Message history is limited there, and plan prices are not provided.

The alternatives below center on calendars, so they may suit teams that mainly schedule appointments and meetings. Compare shared-calendar support, sync direction, time blocking, scheduling links, video meetings, device coverage, and cost. Switching can also mean giving up Lark’s combined chat, documents, storage, workflow automation, integrations, translation, and developer tools. Decide whether your team needs that broader workspace or prefers a focused calendar with the specific scheduling features and platforms it offers.
