Slack review
A capable team-chat hub for integration-heavy teams, with limited free history.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Slack organizes workplace communication around public and private channels, direct messages, shared spaces, and Slack Connect external messaging. It is aimed at teams that need structured conversations alongside searchable message and file history, audio and video huddles with screen sharing, guest accounts, and connections to business tools. Its support across web, Windows, macOS, Linux, iOS, Android, and API makes it suitable for distributed teams working across multiple environments.
The plan structure makes Slack accessible for smaller or trial deployments, but the free tier is deliberately limited. Free is available at no cost per workspace and includes 90 days of message history and up to 10 apps. Pro costs $7.25 per user per month on annual billing and adds unlimited message history, unlimited app integrations, and group meetings. Business+ costs $15 per user per month on annual billing and adds advanced AI features and SAML-based single sign-on. Enterprise+ adds enterprise search and native data loss prevention, with pricing handled through sales. Teams comparing plans should focus on history retention, app limits, meetings, AI, and administrative requirements.
Slack’s strongest case is ecosystem fit. Listed integrations include Salesforce, Jira, Google Drive, ChatGPT, Asana, Miro, Notion, Zendesk, Dropbox, GitHub, GitLab, and PagerDuty, while Workflow Builder supports process automation. AI capabilities include search, conversation summaries, and daily recaps, and higher-tier administration includes SAML single sign-on and SCIM user management. Teams that want a central communication layer around many connected tools should consider Slack. It is a less suitable choice for organizations that need more than 90 days of searchable history without paying or that want predictable Enterprise+ pricing published upfront.
