Dub.co is an open-source link attribution and URL shortener replacing Bitly with branded links, custom social previews, and self-hosted analytics.
A growth marketing team running campaigns across five social channels quickly runs into Bitly's link quotas and domain surcharges. Dub.co handles branded URL shortening, conversion attribution, and custom social share previews from a clean dashboard. The platform pairs a visual interface for campaign editors with an open codebase deployable on independent infrastructure.
Bitly represents the traditional hosted link shortener: an operator configures DNS records, invites marketing staff, and relies on a remote vendor for redirection uptime. While this removes server maintenance duties, it imposes operational limits through monthly link caps, brief analytics retention windows, and steep fees for custom domains or API access. Teams managing expanding link catalogs must pay recurring enterprise fees simply to preserve basic routing.
Dub.co removes those operational limits with an open-source model that teams can self-host or run via managed cloud hosting. Running Dub.co directly ensures ownership of clickstream records, flexible custom domain mapping, and permanent analytics storage without per-link fees. That autonomy brings distinct operational requirements: self-hosting Dub.co means provisioning a Next.js frontend, a MySQL database, a Redis cache, and an analytical engine like Tinybird or ClickHouse. Teams without dedicated operations engineers often pick Dub's hosted service, while engineering teams gain full data sovereignty.
Is Dub.co free to use? Dub.co provides a free tier on its managed cloud service alongside an open-source core, with paid tiers for higher click volumes and enterprise support.
Dub.co vs Bitly — which is better for marketing teams? Dub.co is better for marketing teams needing custom domains, social preview control, and conversion analytics without expensive paywalls, while Bitly suits groups preferring a legacy provider with turnkey publishing integrations.
Can Dub.co be self-hosted on a private server? Yes, the core application can be deployed on private servers, though the setup requires managing MySQL, Redis, and an analytics database pipeline.
Dub.co is an effective choice for marketing teams wanting branded link attribution without Bitly's pricing tiers, provided they either use the managed service or can maintain its multi-service stack. Active maintenance in September 2026 and an AGPL-3.0 codebase ensure organizations retain long-term control over redirection records without vendor lock-in.
Go, gRPC and Protobuf done right, LLM agents in production, and the hard parts of shipping a first product.
