Both handle the conversation. The difference is what the free plan keeps and what each extra person costs.
Pulse comes with your Flaxxa plan, next to the other Flaxxa apps, on one login and one bill.
Pulse doesn't cut off older messages by plan; your plan sets limits such as channels and storage instead.
Canvases, the to-do list and workflows are part of Pulse rather than a paid tier.

Slack is mature, with a very large ecosystem.
Other comparisons
A Microsoft Teams alternative: channels, threads, DMs, canvases, to-dos and workflows in the browser, on Flaxxa plans rather than Microsoft 365.
A Google Chat alternative: channels, threads, DMs, canvases, to-dos, workflows and incoming webhooks on Flaxxa plans, with Google Meet in one click.
A Discord alternative for work: channels, threads, DMs and search with canvases, assignable to-dos, workflows and signed webhooks, on a business workspace.

If you mainly need channels, threads, DMs, search and webhooks, plus simple docs, to-dos and automation, Flaxxa Pulse can be started on Flaxxa's Free plan with no card. If you need native huddles, an app directory or phone apps, Slack's paid plans are hard to beat.
Native importer, free migration support, and a Free plan that lets you compare in your own workspace.
