Each free plan is a trial of one specific thing
Slack's free tier keeps channels, integrations and threads but hides anything older than 90 days, so institutional memory becomes a paid feature. Zoom's free tier is a fine video call that ends at 40 minutes. Meet's is a 60-minute group call in the browser. Teams' free tier is the least restrictive because Microsoft wants the suite. Discord simply does not cap history.
- Slack: history limited to 90 days
- Zoom: 40-minute meeting cap
- Google Meet: 60-minute group call cap
- Discord: no history cap, no time cap on voice
The cost you are already paying
If your company pays for Microsoft 365, Teams is included — so paying for Slack is a decision to buy a nicer chat experience, not to buy chat at all. If your team lives in Gmail and Calendar, Meet is already there and needs no install. Before evaluating anything, check what your existing subscription already contains.
When the 40-minute cap actually matters
For two-person calls and quick standups, Zoom's cap is invisible. For client workshops, classes, interviews and anything with an agenda, it is a real problem that forces a paid plan. If your calls routinely run long, compare Zoom Pro from $13.33/user/mo with what Meet or Teams already give you before you assume Zoom is required.
Chat history is the feature people pay for last
A team can live without a 90-day searchable history right up until the day someone asks 'did we already decide this?' and the answer is gone. Slack Pro at $8.75/user/mo buys the history and more integrations. If your decisions are written down somewhere else, you may never need it; if Slack is where decisions happen, you will.
Where Discord wins and where it fails
Discord is free, unlimited, has always-on voice channels and is excellent for communities, small studios and friend-run projects. What it lacks is business admin: no proper audit trail, no enterprise permissions, no data governance. For anything that touches client data or regulated work, it is the wrong tool regardless of price.
A sensible setup for a small team
Start with what you already own: Teams if you have Microsoft 365, Meet if you live in Google. Add Discord for informal voice if your team wants it. Pay only when a cap bites — Slack Pro when history matters, Zoom Pro when webinars or long client calls become regular. That order keeps the bill near zero until a real need appears.
Frequently asked questions
- Which free video call app has the longest limit?
- Google Meet allows free group calls up to 60 minutes, which is longer than Zoom's 40-minute cap. Discord voice channels have no time limit at all, and Microsoft Teams' free tier is more generous than either, depending on the plan.
- Is Slack's free plan usable for a small business?
- For a small team, yes — channels, threads and integrations all work. The limitation is that messages older than 90 days are hidden, so if your decisions live only in Slack, you will eventually want the paid plan to keep a searchable history.
- Can Discord be used as a business Slack alternative?
- It can, and it is free with unlimited history and always-on voice. The blocker is control: Discord has weak admin tooling, no audit trail and no enterprise permissions, so it suits communities and small informal teams rather than companies handling client data.
- Do I need to pay for video meetings if I have Microsoft 365?
- Usually not for ordinary meetings. Microsoft Teams is bundled with Microsoft 365 and covers chat, meetings and file sharing. You pay separately only for webinar-scale events or extra participant capacity.
