ShiftSee vs. Sling.

Sling has the most generous free scheduling tier in the category. ShiftSee runs your schedule, fills cancellations, and lets workers negotiate — across an external workforce. Different category, different fight.

What it is

What Sling actually is.

Sling is a low-cost employee scheduling and team-communication app, owned by Toast. Free tier for up to 30 users with real shift scheduling, shift swaps, messaging, and task management — genuinely the most generous free plan in the category (CheckThat.ai Sling pricing, March 2026, GetSling.com pricing). Paid tiers: Premium at $1.70/user/month, Business at $3.40/user/month (annual billing).

If your only need is "build the schedule for my existing team without paying anyone," Sling delivers.

The structural wall

Where Sling hits a wall.

No external workforce. No marketplace. No way to reach outside shifters.
No worker negotiation.
Time tracking gated. Free plan has no time tracking — you pay to clock in.
Limited beyond the calendar. No labor cost forecasting on free, no advanced reporting outside Business tier.
Per-user pricing scales. Fine at 30 users; ugly at 100.

What we do that they don't

What ShiftSee does that Sling doesn't.

An external workforce. Targeted shift requests and broadcast fills.
Negotiation on every shift. Rate and time.
A connection graph.
Built-in clock-in included on every account.

Pricing

Pricing in plain English.

Sling free for up to 30 users, then $1.70/user/month (Premium) or $3.40/user/month (Business), annual billing (CheckThat.ai, March 2026).

ShiftSee charges 10% / 10% on completed shifts. If you need a free way to lay out next week's schedule, Sling is genuinely good. If you also need to fill the cancellations Sling can't help with, ShiftSee is what runs underneath.
