Basecamp vs Mattermost

Basecamp is the project management and team communication tool made by 37signals, the Chicago company founded by Jason Fried and David Heinemeier Hansson. It is deliberately opinionated: every project gets the same toolkit of a message board, to-do lists, a schedule, docs and files, a Campfire group chat and automatic check-ins, so people always know where to find things and work stays in writing instead of scattered across chat and email.

Beyond the basics, Hill Charts show how far each piece of work has moved from figuring it out to getting it done, Lineup puts all projects on one timeline, Card Table adds a kanban board, and Timesheets track hours. Clients can be invited into projects with fine control over what they see. Pricing is flat rather than per user: a free plan covers one project, paid Freelancer, Studio and Pro plans are capped by active projects, and Unlimited covers unlimited projects and users at one fixed price, which becomes one of the cheapest options in the market once a company passes roughly twenty people.

Basecamp suits agencies, remote companies and small businesses that value calm, asynchronous communication and simple accountability. It intentionally leaves out Gantt dependencies, custom fields, resource planning and deep reporting, and its integration catalogue is thin. Asana and monday.com are better for structured planning and automations, ClickUp for teams that want every feature in one place, and Linear or Jira for engineering workflows.

Mattermost is an open-source collaboration platform for technical and mission-critical teams. It started as an internal chat tool at a game company and is now developed by Mattermost, Inc. in Palo Alto. Organizations deploy it on their own servers, in private clouds or in fully air-gapped networks, which is why defense agencies, governments, banks and critical infrastructure operators use it.

The core is Slack-style team messaging with channels, threads, direct messages, file sharing, search, and desktop and mobile apps. On top of that come Playbooks for repeatable processes such as incident response, and integrations with GitHub, GitLab, Jira, Jenkins and other DevOps tools through webhooks, slash commands and plugins. Free self-hosted editions cover core messaging, though since version 11 (October 2025) the Entry edition shows only the latest 10,000 messages and Team Edition is capped at 250 users; Professional adds SSO, advanced permissions and guest accounts for a per-user fee; Enterprise adds compliance exports, data retention policies, high availability and advanced security.

Mattermost fits organizations that cannot put their conversations in a vendor-hosted cloud, and DevOps teams that want chat tied to their tooling. The trade-off is user experience and ecosystem: the interface is behind Slack, there are far fewer third-party apps, and self-hosting needs operational effort. Slack and Microsoft Teams are easier if data residency is not a constraint; Rocket.Chat is another open-source option, and Element, built on Matrix, adds federation and end-to-end encryption.
