Dub alternative to Bitly: open-source link infrastructure with an API-first design

Why buyers actually switch from Bitly to Dub

The common thread among people leaving Bitly is that the free plan they built on kept shrinking, and the analytics they wanted kept moving up a tier. Dub's open, API-first model is the reaction.

1. The incumbent kept gating features

Bitly's free plan has narrowed and its analytics depth sits behind paid tiers, so teams that started free found the useful parts increasingly locked. Dub keeps click analytics available without the upgrade wall.

2. No real API-first story

Teams that want to mint and track links programmatically find Bitly's API workable but the deeper features gated. Dub is built API-first with SDKs, so link infrastructure is a first-class part of your product.

3. You can own the whole thing

Bitly is proprietary SaaS. Dub is open source and self-hostable, so teams with data-control or uptime requirements can run it themselves.

Deep dive: Link infrastructure as a product

Dub treats short links as programmable infrastructure rather than a marketing convenience.

API and SDKs

A clean REST API and official SDKs let you create, tag and analyze links from your own code, so links become part of your product's data model.

Deep links and A/B tests

Built-in deep linking and link-level A/B testing cover growth-engineering use cases that Bitly reserves for higher plans.

Deep dive: Owning your link data

Self-hosting

Because Dub is open source, you can run it on your own infrastructure and keep every click event in your control.

Custom domains everywhere

Branded custom domains are a core feature rather than a premium unlock, so your links carry your brand from the start.

Who Dub is actually for

1. The growth engineer

Anyone generating and tracking links programmatically gets an API-first platform instead of a marketing dashboard.

2. The brand that outgrew free Bitly

Teams that hit Bitly's shrinking free limits find Dub's allowance and open model more sustainable.

3. The data-control-conscious team

Companies that want to self-host their link infrastructure can, which Bitly does not allow.

Migration walkthrough: how to switch from Bitly to Dub

Step 1: Claim your custom domain

Add and verify a branded short domain in Dub so new links carry your brand from day one.

Step 2: Export links from Bitly

Pull your existing Bitly links and their destinations via export so you have a full inventory.

Step 3: Recreate branded-domain links

Import links that use a custom domain you own; those can move because you control the domain.

Step 4: Set up the API or Zapier

Wire Dub's API or Zapier integration into wherever you currently generate links automatically.

Step 5: Plan redirects for bit.ly links

Links on bit.ly cannot transfer, so plan a redirect strategy and migrate the highest-traffic ones first.

Step 6: Cut over analytics

Point your reporting at Dub's analytics and confirm geo, device and referrer data is flowing before retiring Bitly.

Objection handling: “Can I keep my existing short links if I move off Bitly?”

Only if you own the custom domain those links use. Links on the shared bit.ly domain cannot be transferred and will break if you cancel, so those need a redirect plan and you should migrate the highest-traffic ones first. Links on a branded domain you control move cleanly, because the domain — not Bitly — is what routes them. The practical approach is to move all branded-domain links immediately, set up redirects for critical bit.ly links during a transition window, and accept that low-value legacy short links may simply be retired. It is a real migration cost, but a one-time one.
