BusyVault vs Slack: flat pricing, no file limits, permanent history
Slack charges per user and hides messages older than 90 days on its free plan, while BusyVault charges a flat fee for the whole team and keeps every message and file forever. BusyVault also adds a third structural level — Server → Channel → Subchannel — plus tickets with SLA and no single-file size limit. Slack remains the stronger pick if your workflow depends on its very large third-party app ecosystem.

When Slack is the better choice
- You depend on a long tail of Slack-only integrations and Slack apps built in-house.
- Your partners and clients are already inside Slack Connect and switching would break shared channels.
- You need a very large marketplace of workflow automations out of the box rather than webhooks you wire yourself.
- Your organisation has a procurement process that already lists Slack as an approved vendor.
When BusyVault wins
- You send large files — design exports, video, datasets — and hit Slack's per-file ceiling.
- You need history that never disappears, for compliance or simply for finding last year's decision.
- Your headcount changes often and per-seat pricing makes budgeting unpredictable.
- You run client or project work that needs a third level of structure below channels.
- You need tickets with an SLA inside the same tool your team already talks in.
- You need EEA data residency, or a fully self-hosted deployment on Enterprise.
Migrating from Slack in 3 steps
1. Export your Slack workspace
Use Slack's built-in export to download channels, messages and files as JSON. Owners can run it from workspace settings; paid plans also cover private channels.
2. Recreate your structure in BusyVault
Map each Slack workspace to a BusyVault Server and each channel to a Channel. Anything that lived as a naming convention (#client-acme-seo) becomes a real Subchannel.
3. Move people, then archive Slack
Invite the team, keep Slack read-only for a two-week overlap, and point integrations at BusyVault webhooks. After the overlap, archive the Slack workspace.
Frequently asked questions
Is BusyVault cheaper than Slack?
For most teams, yes. BusyVault is flat — from $9/month for the whole team — while Slack bills per user each month, so the gap grows with every hire.
Does Slack really delete my old messages?
On the free plan Slack hides messages and files older than 90 days; they become inaccessible until you upgrade. BusyVault keeps full history on every plan.
How large a file can I send in BusyVault?
BusyVault has no single-file size limit, so multi-gigabyte video and design exports go straight into the channel instead of a file-sharing link.
Can BusyVault be self-hosted like Slack cannot?
Yes. Self-hosting is available on the Enterprise plan, which is why regulated and infrastructure-heavy teams evaluate BusyVault against Slack.
Can I keep using my Slack integrations?
Anything built on incoming or outgoing webhooks maps over directly. Slack-marketplace apps do not transfer and need a webhook or API equivalent.
