The Verdict

Lark is built for startups and asian market teams, with a focus on messaging and video-conferencing. Relay.app targets operations teams and agencies and leads with workflow-builder and ai-steps.

Pricing is close: Lark starts at $12/mo versus $16/mo for Relay.app — not a deciding factor on its own.

Both offer free plans, so you can test each with your real workflow before committing to a subscription.

Both tools are a solid fit for small businesses — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.

This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
