Understanding these differences ensures you pick the best tool for your company’s needs.

Key Features and Differences
Slack is built around persistent team messaging. Channels allow teams to organize discussions, share files, and collaborate asynchronously. You can search conversation history, set up private or public channels, and react to messages. Video and voice calls are available, but limited to 1:1 on the free plan.
Zoom is designed for real-time communication. Its main strength is high-quality video conferencing, with support for group meetings, webinars, screen sharing, and breakout rooms. While Zoom has a chat function during meetings, it offers limited ongoing messaging functionality compared to Slack.
Plans, Pricing, and User Limits
Slack: The free plan provides access to the most recent 90 days of message history, supports up to 10 app integrations, and allows 1:1 voice and video calls. Paid plans start at $6.67 per user per month (billed annually), which unlocks additional features and increases limits.
Zoom: The free plan allows group meetings for up to 100 participants but imposes a 40-minute limit per meeting. Paid plans start at $14.99 per month per license, allowing longer meetings and more advanced features. If your business needs frequent, large group sessions, Zoom’s paid tiers provide the necessary scale.
Slack’s user limits on free and paid plans are not publicly specified. Zoom’s primary restriction is meeting participant count and time per session (on the free plan), making these factors critical for teams considering either platform as they grow.
Integration Capabilities
Slack’s free plan allows you to integrate up to 10 third-party apps for added functionality (e.g., file storage, project tracking). Integration limits beyond the free tier are not publicly specified. Zoom’s integration capabilities are not detailed in the available evidence.
In practical business scenarios, app integrations enable workflows across platforms (like connecting project management or CRM tools). Slack’s established integration ecosystem is a draw for businesses prioritizing workflow automation and custom notifications.
Security, Compliance, and SSO
Enterprise security is a top priority for both Slack and Zoom. Slack provides data encryption at rest and in transit, supports SSO (Single Sign-On), and is certified for SOC 2, SOC 3, ISO/IEC 27001, and GDPR compliance. Zoom offers end-to-end encryption, SSO, and compliance with SOC 2, ISO/IEC 27001, and GDPR. Choosing between platforms should involve reviewing your organization’s specific compliance requirements.
HIPAA Compliance and Data Retention
HIPAA compliance is not publicly specified for either Slack or Zoom based on the current evidence. Slack’s free plan retains up to 90 days of message history, while detailed data retention policies for other tiers or for Zoom are not publicly specified. If HIPAA or industry-specific compliance is vital, you should investigate further or reach out to vendor sales specialists.
Collaboration and User Experience
Slack’s channel-based messaging is ideal for ongoing projects, supporting asynchronous communications and file sharing. This benefits teams who work across time zones or rely on thread-based discussions. Zoom’s intuitive interface and reliable video performance make it better suited for live meetings, presentations, and real-time collaboration where face-to-face interaction is preferred. Your team’s daily communication patterns should influence your selection.
Decision Factors: When to Choose Slack vs Zoom
- Choose Slack if your team’s workflow relies on ongoing text discussions, file sharing, and broad integration with other business tools.
- Choose Zoom if your organization requires frequent, large-scale video meetings, screen sharing, or webinars as a primary mode of collaboration.
- Consider user and meeting limits, integration flexibility, and required security or compliance certifications before investing in either platform.
| Scenario | Best Choice |
|---|---|
| Persistent collaboration and app workflows | Slack |
| Frequent video meetings and live sessions | Zoom |
| Cost-sensitive, small teams | Slack (lower starting price) |
| Large group video events | Zoom |
