Basecamp knows the plan.
But your client's calendar doesn't.
Fix that.
Every Basecamp project has its own calendar feed. Feedhammer merges them — and lets you control what each audience sees. Your clients see only what you share. Your team sees only what they need.

Four projects. One client. Their Google Calendar shows nothing.
You configure once. Each audience gets exactly their slice.
Two feeds. Two audiences.

Compatibility and Syncing
Works with your calendar app
Feedhammer produces a standard iCal URL. Paste it into any calendar app once — it stays current automatically.
Google Calendar Outlook Apple Calendar Thunderbird Hey Calendar Any iCal app
Sync frequency
Your calendar app pulls the feed on its own schedule — no tool controls this.
Google Calendar: every 5–8 hours.
Outlook: roughly once a day.
Apple Calendar: as per your refresh settings.
Thunderbird: as per your refresh settings.
Reasonable-time sync our term for it
Last-minute plans don't live on calendars. They live in the conversation where they were made. What belongs on a calendar was planned ahead — and that syncs just fine.
Plans
Starter $12/mo Up to 10 feed groups · For freelancers Pro $29/mo Unlimited groups · Team access · White-labelAll Plans
Search & Sort
Find any feed group in seconds with keyboard-focused search. Sort by name, creation date, or last synced — however your brain organises things.
All Plans
Revoke & Replace Feed URL
Shared a feed URL with someone you no longer want to have access? Kill it in one click. The old URL stops working instantly — paste the new one wherever you need.
All Plans
Duplicate Feed Group
Same Basecamp projects, different audience. Duplicate any group as a starting point, adjust the filters, and share a fresh URL. Useful when clients need meetings-only and your team needs everything.
All Plans
Event Filtering
Every Basecamp project mixes meetings, to-dos, and card milestones. Choose exactly which types appear in each feed group — per group, not per account. Clients see only what's relevant to them. You see everything.
Pro
Bulk Operations
When you're managing 20+ feed groups across clients and projects, one-by-one updates don't scale. Select multiple groups at once and regenerate URLs or delete them in bulk — so a client offboarding or a full URL refresh doesn't eat your afternoon.

Pro
Team Access
You keep the billing and account control. Your team gets full access to create and manage feeds. Add up to 2 teammates — 3 seats total including you — each signing in with their own Google account. One subscription covers the whole team.
Pro
Custom Calendar Name
By default, your feed shows up as Feedhammer in Google Calendar. Pro lets you set your own name — so clients see your agency or brand, not ours. Set it before sharing your feed URL: Google Calendar captures the name on first subscription and won't update it afterward.
Pro
Export & Import
Back up your entire Feedhammer setup or migrate it to a new account — every group, every source, every setting, in one JSON file. Export for peace of mind, import to rebuild after a switch or share a tested configuration with your team.

Does my client need a Feedhammer account?
No. You create the feed group, they receive a URL. They paste it into their calendar app — that's the entire interaction on their end. One URL can be shared with as many people as you like. There's no per-person limit, no seat count, no separate login for anyone receiving the feed.
Will events update automatically when Basecamp changes?
Yes — within your calendar app's sync window. Google Calendar typically refreshes every 5–8 hours. The feed always reflects your current Basecamp projects; the only variable is when the app next checks.
Can I share the same feed URL with my whole team?
Yes. A single feed URL works for any number of people simultaneously. If you want different people to see different things, create separate feed groups — each gets its own URL with its own filter settings.
What happens if I cancel my subscription?
Your feed URLs stop serving data. Anyone who added them will see an empty subscription. Give your clients a heads-up before cancelling so they can remove it cleanly from their calendar.
Can I pull from multiple Basecamp workspaces?
Yes. A feed group accepts iCal URLs from any Basecamp workspace. No restriction on accounts or workspaces per group.
