The Best Free Design Tools for Indie Developers

Shipping something on your own means doing the design work too, usually at the point where you would rather be writing code. You do not need a design education for this — you need a short list of tools that do the specific jobs that block a launch.

This is that list. Everything here has a genuinely usable free tier, and where the free tier has a catch, the catch is stated. Nothing is ranked by popularity; they are grouped by the job they unblock.

Interface design

Figma is the default, and the free tier is unusually generous: unlimited personal files, three collaborative files, real dev-mode inspection so you can pull exact values into CSS. For a solo developer the three-file limit is rarely the thing that bites. Learn frames, auto-layout and components and you have covered most of what you will do.

Penpot is the open-source alternative, self-hostable, with no file limits at all. It is genuinely good and improving quickly. Choose it if you object to depending on a hosted service, or if you have hit Figma's collaboration cap.

If you have never opened a design tool, start by rebuilding a screen you already like rather than designing from scratch. Copying teaches spacing and hierarchy faster than any tutorial. Whatever you settle on, export your logo as a vector master — SVG vs PNG for logos explains why that one file saves you every later request.

Icons

Lucide — around 1,500 MIT-licensed icons, consistent stroke weight, packages for every major framework. This should be your default; consistency across a whole UI matters more than any individual icon.

Heroicons — from the Tailwind team, in outline and solid variants. Pairs naturally with Tailwind.

Simple Icons — brand logos for "sign in with…" buttons and integration pages, which the general sets deliberately do not include.

The rule that matters: pick one set and stay in it. Mixing icon families is one of the most visible signs of an unfinished interface, and it is entirely avoidable.

Fonts

Google Fonts — free for commercial use, no attribution, self-hostable. Inter, Geist and Source Sans are safe, and safe is correct here.

Fontshare — free commercial fonts with noticeably more personality than the Google defaults. Useful when everything you make looks like everything else.

Two rules: use at most two families, and set display: swap so text paints immediately rather than after a font download.

Colour

Coolors for generating palettes quickly and Realtime Colors for the more useful exercise — seeing a palette applied to an actual page layout instead of as six squares.

For accessibility, the WebAIM contrast checker is the reference. Aim for 4.5:1 on body text. This is the single easiest accessibility win available and it takes seconds.

If you already have a logo and need a palette that agrees with it, deriving one from the mark is more reliable than picking swatches in the abstract — our palette generator pulls the dominant colours out of an image and suggests harmonious secondaries.

Illustration and imagery

unDraw — open-licence illustrations whose accent colour you set before download, so they match your brand. Widely used, which is the trade-off.

Unsplash and Pexels for photography, free for commercial use. Applying a consistent treatment — a duotone in your brand colours, for instance — is what stops a page of stock photos from looking like a page of stock photos.

Screenshots and marketing assets

This is where most indie launches lose time, because it is the least interesting part.

Shots and Screely wrap raw screenshots in device frames and backgrounds, which is the difference between a landing page that looks shipped and one that looks like a work-in-progress.

Excalidraw for architecture diagrams. Hand-drawn styling reads as explanatory rather than corporate, and it is fast.

Squoosh for compressing images before they ship. A 2 MB hero image is a real performance problem and this fixes it in the browser.

Asset preparation

The last mile: you have a logo, and now every surface wants it in a different form. A favicon. A white version for the dark header. A transparent PNG for the README. A square icon for the app store. An OG image at exactly 1200×630.

This is the job ICC Images exists for — we build it, so treat this entry as interested rather than neutral. It runs in the browser, colour edits happen locally, and you can recolour a logo, remove a background, or generate every size at once without opening a design application. Editing and previewing are free without an account; a free account plus credits is needed to download full-resolution files, and AI operations like background removal are pay-per-use rather than free. Credits do not expire and there is no subscription — which is the right shape when you need this a few times a month rather than daily.

If you would rather stay in one tool, Figma does all of the above too. It is more setup per task and more capability overall; the trade is convenience against control.

What you do not need

Worth saying, because the temptation is real when you are procrastinating on the hard parts:

• A design system. Not for v1. Use a component library — shadcn/ui or similar — and build your own only when you have felt the pain.
• A custom icon set. Nobody has ever chosen a product for its bespoke icons.
• A logo before you have users. Set your product name in a good typeface and move on. You will rebrand anyway.
• Paid stock photography. The free libraries are more than adequate at this stage.

A minimum stack

If you want one recommendation rather than a menu:

Figma for screens, Lucide for icons, Google Fonts for type, Realtime Colors for the palette, Squoosh for compression, and something to prepare the logo variants. That is enough to launch, and every piece of it is free.

The bottleneck on an indie launch is almost never the tools. It is deciding to stop adjusting things and ship.
