Where Dub earns its reputation
Dub grew up in public, on GitHub, which gives it a level of transparency and developer trust that a closed-source competitor can't easily replicate — anyone can inspect how it actually works before committing to it. That open-source foundation, combined with a genuinely clean API and documentation aimed squarely at engineers, has made it a popular default for startups and technical teams who want link infrastructure they can wire directly into their own product rather than manage by hand in a dashboard.
A links-and-API company vs. a links-QR-bio company
The core difference is scope. Dub is built to do one job — link creation and management, programmable and transparent — extremely well. Shorter.gg treats a short link, a QR code, and a bio-page block as three views of the same underlying destination, sharing one dashboard and one set of analytics. If your team's whole workflow is programmatic (links created and managed through code, not a UI), that narrower focus is a genuine strength. If you also want QR codes and a bio page without adding another vendor, it's a gap.
Open source: a genuine, specific differentiator
This is worth calling out plainly: Dub's open-source availability and self-hosting option are real capabilities that Shorter.gg, like most competitors in this space, doesn't offer. For a team with strict data-residency requirements, a preference for owning its own infrastructure, or simply a cultural preference for open tooling, this can be the deciding factor on its own, independent of any feature comparison.
QR codes and bio pages: not part of Dub's scope
Dub does offer QR code generation for its links, but it isn't the deeply integrated, brand-customizable experience Shorter.gg builds around every short link, and Dub doesn't offer a link-in-bio page product at all. A team that wants those two pieces alongside its links would need to add separate tools rather than finding them already built in.
API access on both platforms
Both platforms expose a developer API for creating and managing links programmatically, and both are reasonable choices for that use case. The difference is breadth: an integration built against Shorter.gg's API can also touch QR codes and bio pages through the same credentials, while Dub's API is scoped tightly around its core link-management product — which, for a team that only needs links, is arguably a simpler surface to build against.
Analytics and reporting
Both platforms track clicks by device, location, and referrer, giving a reasonably complete picture of who's engaging with a link and from where. Neither has a meaningful edge here — the real decision point is elsewhere, in scope and deployment model, not analytics depth.
Who each platform actually fits best
Dub tends to fit engineering-led teams and startups that want programmable, transparent link infrastructure and value the option to self-host, especially if links are created and managed primarily through code rather than a dashboard. Shorter.gg tends to fit teams and creators who want short links, QR codes, and a bio page functioning as one connected product, accessed through a UI as often as an API.
Switching considerations
Moving between the two mainly involves re-pointing your branded domain and recreating your link structure, or migrating link data if you're coming off a self-hosted Dub instance specifically. Because both expose an API, most of that migration work can itself be scripted rather than done by hand, which is a small but real convenience either direction.
A note on picking based on team, not just features
This comparison comes down less to a feature checklist than to who's actually going to use the tool day to day. If that's primarily engineers integrating links into a product, Dub's developer-first design and open-source transparency are worth real weight. If it's a broader team — marketing, social, ops — that also wants QR codes and a bio page without learning an API, Shorter.gg's more general-purpose design tends to fit better.
What self-hosting actually commits you to
Before choosing Dub specifically for its self-hosting option, it's worth being honest about what that entails: you're now responsible for uptime, security patching, and infrastructure costs that a hosted platform otherwise absorbs for you. For a team with the engineering capacity and genuine reason to self-host — compliance, data residency, cost at extreme scale — that tradeoff is worth making. For a team without a dedicated infrastructure function, it can quietly become its own maintenance burden.
Migrating an existing Dub setup
If you're self-hosting Dub and considering a move to a hosted platform like Shorter.gg, migration means exporting your link data (Dub's open-source nature makes this more transparent than migrating off a closed-source competitor) and recreating your domain and redirect structure on the new platform. Teams coming from Dub's cloud-hosted version have an even simpler path, since it's already a standard SaaS migration rather than a self-hosted-to-hosted transition.
