Every small dev team runs on free tiers. Free GitHub, free Slack, free Vercel, free tier of whatever board tool won the last argument. The invoice says $0, so the cost is $0, right?
Not quite. Free tools charge in currencies that don’t show up on a credit card statement, and three of them get expensive fast.
Currency 1: The cliff
Free tiers are designed funnels, and the funnel has a wall built into it. Slack’s free tier deletes message history past 90 days — which means your team’s institutional memory quietly evaporates until you pay roughly $8.75/user/month to get it back. Notion’s free plan caps collaboration features right around the moment a second person becomes essential. Trello’s free tier limits automation runs; your board gets dumber exactly as your process starts depending on it.
The pattern: the free tier isn’t priced at your team today. It’s priced at the team you’ll be in six months, when migration is painful and the upgrade button is one click away. The $0 was a loan.
Do the math for a five-person team hitting three of these cliffs in a year: chat history ($525/yr), docs ($600/yr), board ($720/yr). Your “free” stack quietly becomes $1,845/year — more than many paid-flat tools would have cost from day one.
Currency 2: Attention
Free tools answer to advertisers, engagement metrics, or upsell funnels — not to you. That’s why your “free” standup bot pings you about upgrading, your free board shows banners for the enterprise plan, and the free chat app nudges you toward features that need a paid tier to use.
Each nudge is small. The sum isn’t. A team of five losing even two minutes a day each to dismissals, workarounds, and upgrade-modal whack-a-mole burns ~40 hours a year — a full work-week, spent negotiating with your own tools.
Currency 3: Migration risk
The deepest cost of a free tool is that you build your process inside a product whose roadmap you don’t control and whose pricing can change overnight. Teams that lived through the Heroku free-tier sunset, or the Docker Desktop licensing change, know how this feels: your workflow was load-bearing, and the terms changed.
The honest test: if this tool doubled its price tomorrow, would we pay, or would we leave? If the answer is “we’d pay,” you were never on a free tool — you were on deferred billing. If it’s “we’d leave,” then ask how many weeks leaving would cost, and who on your team owns that project.
What to do about it
You don’t need to swear off free tiers — some are genuinely generous and stable (GitHub’s core offering has been free for years without funny business). You need to audit them once a year with three questions:
- What’s the cliff, and when do we hit it? Put the date on the calendar before the tool does.
- What’s the upgrade price at our actual headcount? Per-seat pricing at 5 seats is trivia; at 12 it’s a budget line.
- What’s our exit cost? Export formats, API access, data portability. Free tools that hold your data hostage aren’t tools; they’re leases.
The alternative shape
The tools worth betting a small team on have boring pricing: flat, published, and sized for teams like yours. Not because cheap is virtuous, but because boring pricing means the tool’s incentives point the same direction as yours — keep you shipping, not keep you upgrading.
That’s the bet behind Kahoona: free to start, one flat price when you grow, and your board builds itself from your repo so you’re not paying anyone — us included — with your team’s attention.
