Where Rebrandly earns its reputation
Rebrandly's whole pitch is that a link is a piece of your brand, not just a redirect, and it has built its product around that idea more single-mindedly than most competitors. It supports attaching multiple branded domains to one account, which appeals specifically to agencies managing links across several client brands from a single login, and its API-first design has made it a common choice for developers building link creation directly into another product or internal tool.
A domain-and-links company vs. a links-QR-bio company
The clearest way to understand the difference is scope. Rebrandly is, at its core, a branded link management company — everything it builds serves that one job well. Shorter.gg treats a short link, a QR code, and a bio-page block as three ways of sharing the same underlying destination, all sharing one dashboard, one set of analytics, and one login. If your needs stop at branded links, that narrower focus isn't a weakness. If you also want QR codes and a bio page without adding another vendor, it becomes a meaningful gap.
QR codes: available, but not the main event
Rebrandly does offer QR code generation, but it reads as an addition to a link-management product rather than a feature built with the same depth as its domain and link tools. Shorter.gg's QR codes are generated from the same engine as every other link on the platform, which means a QR code automatically inherits click analytics, expiration dates, and password protection the same way a standalone short link does, without separate setup.
No bio page at all
Rebrandly doesn't offer a link-in-bio page product — it isn't part of what the company builds. If you need a page that gathers several links behind one profile for a social bio, Rebrandly isn't the tool for that job on its own, and you'd need a second product alongside it. Shorter.gg includes bio pages in the core plan specifically so that a business or creator doesn't need a separate subscription just to cover that one use case.
Retargeting pixels: a genuine Rebrandly strength
One feature worth calling out honestly: Rebrandly supports attaching retargeting pixels (like a Meta or Google Ads pixel) to a shortened link, so that anyone who clicks it gets added to an ad-retargeting audience even before they land on the destination page. This is a specific, useful capability for performance-marketing teams running paid campaigns, and it isn't something Shorter.gg markets itself around. If pixel-based retargeting on every link is a hard requirement for your workflow, that's a legitimate reason to weigh Rebrandly seriously.
API access and building links into other tools
Both platforms expose a developer API for creating and managing links outside of the dashboard, and both are reasonable choices if you're generating links programmatically from another system. The difference again comes down to scope: an integration built against Shorter.gg's API can create a short link, a styled QR code, or a bio-page entry through the same credentials, while an integration built against Rebrandly's API is working within a link-and-domain-focused feature set.
Switching considerations
Moving between the two mainly involves re-pointing your branded domain's DNS records to the new provider and recreating your existing links (or accepting that old ones keep resolving on the old platform while new links go elsewhere). Because both platforms support custom domains and bulk import, the technical part of switching is usually straightforward — the bigger question is simply whether your team needs QR codes and bio pages bundled in, or whether pixel-based retargeting on every link is the feature you can't do without.
Who each platform actually fits best
Rebrandly tends to fit performance-marketing and growth teams that live inside ad platforms and specifically want retargeting pixels on their links, along with agencies juggling several client domains from one account. Shorter.gg tends to fit teams and creators who want branded short links, QR codes, and a bio page to function as one connected product, without needing a second tool just to cover the QR or bio-page use case.
Agency workflows and client reporting
Agencies managing links on behalf of multiple clients tend to care about two things above all: keeping each client's links cleanly separated under their own branded domain, and being able to pull clean reporting for each one without mixing data across accounts. Rebrandly's multi-domain support was built with exactly this workflow in mind. Shorter.gg's team workspaces cover a similar need — separate branded domains and separate analytics per workspace — though without the retargeting-pixel layer that some performance-focused agencies specifically build their reporting around.
