The Free, Open-Source Flowcode Alternative
Both create QR codes, but they sit at opposite ends of the market. Flowcode is a premium, design-led platform built around dynamic codes, scan analytics, and landing pages - powerful, but account-based and paid for anything serious. KoloQR is a free, open-source generator for print-ready static codes you can design and download in seconds, with no account. Here's an honest side-by-side to help you choose.
Feature Comparison
The areas where KoloQR leads on design freedom and access. Flowcode's own strengths - dynamic codes, analytics, and landing pages - are covered in the overview below.
Downloads Without Sign-up
KoloQR downloads need no account. Flowcode requires you to create an account before you can download any code.
KoloQRYesFlowcodeNoOpen Source
Inspect, modify, and self-host the KoloQR source code. Flowcode is a proprietary, hosted platform.
KoloQRYesFlowcodeNoCustom QR Shapes
Circular, rectangular, triangular, and hexagonal outer shapes. Flowcode styles pattern, color, and frame within a square code.
KoloQRYesFlowcodeNoPremium QR Frames
Ready-made frames with a call to action. Both tools offer these.
KoloQRYesFlowcodeYesVector Export (SVG, PDF, EPS)
Both export vectors, but KoloQR's are free and unwatermarked. Flowcode's SVG needs a paid plan and free codes carry a watermark.
KoloQRYesFlowcodeYesCopy Straight to Figma
Paste a QR code into a Figma file without exporting and re-importing.

Generate a QR code from any open webpage in one click.

Where Each Tool Actually Leads
The table only tells part of the story. KoloQR and Flowcode are built for different jobs. Here's the honest picture so you can choose the right tool rather than the one with the longest feature list.
KoloQR: Free, Permanent, Design-Flexible Static Codes
If you want a print-ready QR code in seconds - no account, no watermark, and a code that keeps working no matter what - KoloQR is the simpler path.
- Custom Shapes - Circular, hexagonal, triangular, and rectangular codes, plus logo support and full color control.
- No Account, No Watermark - Download high-quality PNG and vector files without signing up, and with no branding added to your code.
- Codes That Don't Expire - Static codes are encoded directly, so they never expire and don't depend on a platform account or subscription staying active.
- Print-Ready and Open Source - Free SVG, PDF, and EPS export, a contrast checker, plus source code you can inspect and self-host.
KoloQR makes static QR codes. Because the link lives in the code itself, it's platform-independent - you can switch tools anytime without reprinting. The trade-off is that you can't change the destination or track scans once it's printed.
Flowcode: Premium Design, Tracking, and Landing Pages
If you want polished branded codes, scan analytics, landing pages, and lead capture in one platform, Flowcode is built for that - and KoloQR isn't.
Flowcode is a design-led marketing platform, known for high-quality branded codes, dynamic destinations you can edit after printing, and real-time analytics by location, device, and time. It adds Flowpage landing pages, first-party data collection, CRM integrations, bulk generation, an API, and strong privacy compliance (GDPR, CCPA, SOC2). The trade-offs: you need an account to download anything, the free plan adds a watermark and caps scans, SVG export and serious features sit on paid plans from $25/month, and because the codes are dynamic they're tied to Flowcode - if the subscription lapses, they stop working. Choose Flowcode when tracking, landing pages, and data collection matter more than free, permanent, platform-independent codes.
Generate QR CodeHow to Choose - and How to Make a QR Code That Actually Scans
Whichever tool you pick, a few habits keep your codes reliable in the real world. These matter more than most feature lists admit.
Match the Tool to the Job
Need to edit the link, track scans, or capture leads after printing? A dynamic platform is the right call - just check the free-tier limits, like watermarks or scan caps. Just need a clean, permanent link? A static code is simpler, free, and platform-independent.
Keep Static Codes for Permanent Links
Menus, business cards, and packaging that point to a stable URL work fine as static codes - no account, no watermark, and no risk of the code dying if a subscription lapses.
Watch for Platform Lock-in
A dynamic code routes through the vendor's servers, so it only keeps working while your account does. If you print at scale, plan for what happens if you stop paying - static codes have no such dependency.
Test on Real Phones Before Printing
Scan with both an iPhone and an Android using the native camera. A code that reads on screen can still fail on paper at small sizes.
Respect the Quiet Zone
Leave clear space around the code, roughly four modules wide. Crowding it is the most common reason a code won't scan.
Keep Strong Contrast
Dark code on a light background scans best. Light-on-dark can work, but low-contrast or busy backgrounds break scanning. A contrast checker catches this before you print.
Size for Scanning Distance
A rough rule: the code should be about a tenth of the distance it's scanned from. A poster read from 3 m needs a code around 30 cm wide.
Use Vector Files for Print
Export SVG, PDF, or EPS so the code stays crisp at any size. PNG is fine for screens and small prints but degrades when scaled up.
Add a Logo Carefully
A centered logo builds trust, but keep it small and raise the error-correction level so the code stays readable.
Don't Rely on Style for Scannability
Shapes and colors are fine, but they don't speed up scanning - legibility does. Style within the limits of contrast and quiet zone.
Tell People What to Expect
A short prompt like 'Scan for the menu' lifts scans more than any design trick. People scan when they know what they'll get.
Questions? Answered
Yes, if you want free, design-flexible static QR codes with no account and no watermark. KoloQR offers custom shapes, logos, and free vector export, and it's open source. It isn't an alternative for Flowcode's dynamic codes, analytics, or landing pages - those it doesn't offer.
KoloQR makes free static codes with no account and no watermark, and the codes are permanent. Flowcode is a premium platform built around dynamic codes, analytics, and landing pages, with an account required and paid plans for anything serious. One is about free, permanent codes; the other about tracking and marketing.
Yes. Flowcode's own generator asks you to create an account before you can download, even on the free plan. KoloQR lets you download PNG and vector files instantly, with no sign-up.
On its free plan, yes - free Flowcode codes carry a watermark and a 500-scan cap, and SVG export requires a paid plan from $25/month. KoloQR's codes are unwatermarked and its vector export is free.
No. KoloQR makes static codes, where the data is fixed in the code. They never expire and need no account, but you can't change the destination or track scans after printing. For that, a dynamic platform like Flowcode is the right choice.
No. Static codes are encoded directly and keep working as long as the destination page is live. Dynamic codes, like Flowcode's, route through the platform and can stop working if the subscription lapses.
Yes. Circular QR codes are a core KoloQR feature, along with rectangular, triangular, and hexagonal shapes. Flowcode offers strong branded styling - colors, logos, patterns - but keeps the standard square outer shape.
It depends on your needs. For a stable menu link, a free static KoloQR code is simple, unwatermarked, and never expires. If you update the menu often, want scan numbers, or want a branded landing page, Flowcode's dynamic codes and Flowpage are worth the subscription.
No. KoloQR doesn't track scans, since a static code carries no redirect to measure. If analytics matter - location, device, time - Flowcode is built for that and KoloQR isn't.
Yes. You can inspect, modify, and self-host the KoloQR source code. Flowcode is a proprietary, hosted platform, so its code isn't available to review or run yourself.
Yes. Export SVG, PDF, or EPS free and the code stays sharp at any size, from a business card to a billboard. Flowcode also offers vector export, though on a paid plan.
Design Your QR Code in Seconds - Free
If your project needs a beautiful, print-ready static QR code with no account, no watermark, and no subscription, KoloQR is the quickest way there.
And if you need dynamic codes, scan analytics, landing pages, or lead capture, Flowcode is a strong, design-led choice - we'd rather point you to the right tool than pretend one size fits all.
