Projects outgrow chat
As projects become more complex, teams need more than conversations and task lists. Integrations or add-ons are needed for structured data, flexible views, dashboards, and automated workflows.
alternativesThe best Slack alternative
Looking for a Slack alternative that brings messaging, docs, meetings, and project management into one place? Lark replaces your scattered tool stack with a single AI-powered workspace without juggling subscriptions or switching between apps.
Why look for a Slack alternative?
Costs grow with your stack
Slack's free plan limits searchable message history to 90 days. As teams scale, paid Slack plus additional tools for broader productivity and business workflows can push total software costs higher.
Too many tools around Slack
Slack connects with thousands of apps, but when projects, docs, meetings, and workflows live in separate tools, managing all the apps, subscriptions, permissions, and integrations becomes a real burden.
Why Lark is the best Slack alternative
Go beyond task lists with Lark Base. Organize complex projects, build custom databases, create dashboards, and automate workflows, all without leaving your workspace.

FAQs about Slack alternatives
What is Slack used for?
Slack is a channel-based messaging platform that helps teams communicate in real time through organized channels, direct messages, and threaded conversations. It also supports file sharing, app integrations, and lightweight audio/video calls. However, Slack focuses on messaging only, without docs, project management, video conferencing, or email.
Are there free alternatives to Slack?
Yes. Lark is the best free Slack alternative, with a free plan supporting up to 20 users, 100 GB of storage, 18 months of message history, video meetings, collaborative docs, project management, and approval workflows all in one app. Discord also provides free messaging and voice channels, though it lacks business features like compliance, admin controls, and document collaboration.
What is the best Slack alternative for businesses?
Lark is the best Slack alternative for businesses because it replaces not just Slack but also the docs, meetings, project management, and workflow tools you would otherwise buy separately. At $12/user/month (Pro), Lark supports up to 500 users with 15 TB storage and 500 participant video meetings, delivering more capability at a lower total cost than Slack Pro plus its required add-ons.
Can I migrate from Slack to another platform?
Yes. Most Slack app alternatives offer data migration support. Lark provides a dedicated migration team that helps transfer your channels, files, and integrations with expert guidance. Microsoft Teams and Google Chat also offer import tools for Slack workspace exports.
Is Microsoft Teams better than Slack?
It depends on your existing stack. Teams is better if your organization already uses Microsoft 365 and needs deep Office app integration. Slack is better for teams that value a lightweight, integration-rich messaging experience. Neither includes built-in docs, project management, or approval workflows in the way Lark does as an all-in-one platform.
Is there an open source Slack alternative?
Yes, there are several options if you are looking for an open source Slack alternative. Platforms like Mattermost, Rocket.Chat, and Zulip provide robust open-source communication solutions that allow organizations to self-host their data and customize the software extensively.
