The honest answer to “which design tool should I use” is that it matters far less than the internet suggests. Every serious tool in this category can draw the same rectangle. What differs is the friction around the rectangle — handoff, versioning, whether your collaborators can open it.
So this is organised by the friction each tool removes, not by feature count.
Pick by who else has to open the file
| Your situation | What actually matters |
|---|---|
| Working alone, no handoff | Whatever you are fastest in. Genuinely. |
| Handing off to developers | Inspect mode, tokens, a link that works without an account |
| Clients review the work | Comment-in-browser, no install, no login |
| Several designers, one product | Shared components, branching, version history |
| Startup, no budget | A free tier that does not expire your files |
| Offline or restricted network | A desktop-native app that stores files locally |
Three things worth checking before committing
- Can you get your work out? Not “is there an export button” — does the export open somewhere else with the layers intact? Test it with a real file on day one, not in year two when you want to leave.
- What happens to files if you stop paying? Read-only access is normal and acceptable. Files locked away entirely is not, and it is worth knowing which you are signing up for.
- Does the free tier have a file limit or a feature limit? A feature limit is survivable. A file limit becomes a problem exactly when you are busiest.
Where the time actually goes
Designers consistently overestimate how much of the day is spent drawing. In practice a working week looks closer to this:
| Activity | Share of a typical week |
|---|---|
| Drawing and layout | ~30% |
| Revising after feedback | ~25% |
| Explaining decisions | ~20% |
| Finding and organising files | ~10% |
| Preparing handoff | ~10% |
| Talking to users | ~5% |
Which means a tool that makes drawing 20% faster saves you 6% of a week. A tool that removes the file-finding problem, or lets a client comment without an account, saves you more — and neither of those shows up in a feature comparison.
What actually speeds up a small team
- One file naming convention, written down. Unglamorous, and it removes the 10% above almost entirely.
- A components file, however small. Even five components — button, input, card, modal, nav — stops the drift that makes a product look assembled from parts.
- A shared link that never expires. The number of review cycles lost to “can you re-send the link” is genuinely absurd.
- Screens named for the state, not the number. “Checkout — card declined” beats “Screen 14” the moment anyone else opens the file.
None of that requires buying anything. All of it saves more time than switching tools would.
When switching is worth it
Switching a whole team costs weeks — migrating files, rebuilding components, everyone slower for a month. That is worth paying when a specific, named thing is broken:
- Developers cannot get what they need without a designer present
- Two people cannot work on the same product without overwriting each other
- Clients need an account and will not make one
- Pricing changed and the maths no longer works
“The other one looks nicer” is not on that list, and it is the reason most switches happen.
Common questions
Do I need a separate prototyping tool?
Rarely. Built-in prototyping covers most questions; a dedicated tool earns its place only for complex motion or logic-driven flows. Match the fidelity to the question you are answering.
Is AI useful in design tools yet?
For filler content, variants of something that exists, and boring resizing work — yes, meaningfully. For deciding what to make — no, and that remains the actual job.
How do I choose without trying everything?
Pick the row in the first table that matches you, try the two obvious candidates for a week on real work, and stop. The marginal difference between the top options is smaller than a week of your own habit.
When is a design system worth building?
Once more than one person builds interfaces — that is the threshold. Before that, a documented set of colours, spacing and button styles does the same job for a fraction of the effort.
