Best URL Shortener: 6 Tools Compared Head-to-Head
A deeper, six-tool comparison for anyone who already knows they need a URL shortener and wants specifics rather than a long list.

Why a shorter list is more useful than a longer one
Broader roundups are useful for discovery, but once you already know you need a URL shortener, a list of fifteen options mostly adds noise. This comparison covers six tools in real depth: Bitly, Dub, Short.io, Rebrandly, Bl.ink, and UTMLoop, evaluated on the same five criteria for each so you can compare like for like rather than reading six separate marketing pages.
The five criteria are pricing structure, custom domain support, analytics depth, team and permission features, and API or integration maturity.
How we scored each tool on these five criteria
Pricing structure was assessed by comparing what a fixed, identical usage scenario (a single team of five, a few thousand links a month, one custom domain) would cost at each vendor's published rates, rather than comparing entry-level prices that don't reflect real usage. Custom domain support was scored on both whether it's included and at what tier, plus whether more than one domain is supported at all.
Analytics depth was judged on whether reporting goes beyond raw clicks into referrer, device, geography, and UTM-parameter breakdowns, and whether that data is exportable. Team features were scored on whether role-based permissions exist at all and how granular they get. API maturity was judged on documentation quality, the range of endpoints covered, and, where relevant, the size of the surrounding developer community for troubleshooting.
Bitly: pricing structure and analytics depth
Bitly prices on a per-link and per-click basis across tiers, which means costs scale with usage in a way that's predictable but can get expensive for high-volume senders. Analytics cover click counts, referrer, device, and location, which is enough for most general reporting but doesn't break down by UTM parameter in a structured way without manual tagging.
Custom domains are supported starting on a mid-tier plan. Team features exist on higher tiers with basic role permissions. Its API is mature and well-documented, reflecting Bitly's long history, making it a safe integration choice even if the dashboard experience feels dated next to newer entrants. The tradeoff worth flagging directly: Bitly's per-click pricing component means a link that unexpectedly goes viral can push your bill up in a way that a flat volume-based competitor like Short.io wouldn't.
Dub: pricing structure and analytics depth
Dub's pricing is volume-based with a genuinely useful free tier, and its paid tiers are competitively priced relative to Bitly for comparable features. Its analytics dashboard, built with real-time updates, shows device, geography, and referrer breakdowns cleanly, with UTM parameter views available if you tag links manually.
Custom domains are included even on lower paid tiers, which is a meaningful cost advantage over Bitly. Team features are present but simpler than Bitly's, reflecting Dub's newer, smaller-team-oriented product. Its API and open-source nature make it the strongest integration option for teams with in-house engineering.
Short.io: pricing structure and analytics depth
Short.io undercuts most competitors on price at every volume tier, and unusually includes a custom domain even on its free plan. Analytics are functional but less visually polished, presented in more of a raw data table format that power users may prefer and casual users may find less intuitive.
Team features exist on paid tiers but are less refined than Bitly's permission system. API access is available and reasonably documented, though the developer community around it is smaller than Dub's, meaning fewer community resources if you hit an edge case. Its biggest limitation for a marketing-first team is that its UTM reporting requires you to tag links manually and consistently yourself; there's no saved taxonomy or enforcement layer, so consistency depends entirely on team discipline rather than the tool.
Rebrandly: pricing structure and analytics depth
Rebrandly prices around link volume and number of custom domains, making it comparatively expensive if you need several branded domains at once, though each domain gets clean, isolated management. Analytics cover the standard set (clicks, location, device) with decent export options for further analysis elsewhere.
Where Rebrandly shines is domain-level team permissions, useful for agencies managing multiple clients' branded links under one account without cross-client visibility. Its API supports domain and link management well, making it a common choice for agency-built integrations. Its weaker spot relative to the others here is UTM-specific reporting, which exists but reads as an afterthought bolted onto a domain-management-first product rather than a core design principle.
Bl.ink: pricing structure and analytics depth
Bl.ink's pricing sits well above the other five tools here, reflecting its enterprise focus. That price buys SSO, detailed audit logs, and compliance features relevant to regulated industries. Analytics are comprehensive but the dashboard is built more for compliance review than fast marketing iteration.
Team features are the most granular of the six, with role-based access down to individual link ownership. Its API is solid but documentation leans toward enterprise IT teams rather than quick self-serve integration, consistent with its target customer. Onboarding tends to run through a sales conversation rather than a self-serve signup, which fits its enterprise buyer but is a genuine friction point for anyone hoping to trial it quickly on their own.
UTMLoop: pricing structure and analytics depth
UTMLoop prices around team seats and tracked link volume, with a straightforward free tier for testing described on the pricing page. Its analytics are structured specifically around UTM parameters, so campaign, source, and medium roll up into reports without needing a separate manual tagging step, which is the core difference from the other five tools here.
Custom domains and team roles are available on paid tiers, and the features page details QR code generation and bulk link creation alongside the UTM builder. Its API is newer than Bitly's or Dub's but covers the core create, read, and reporting endpoints most integrations need.
Head-to-head: which wins on each criterion
On price at low-to-mid volume, Short.io and Dub lead. On analytics depth for general clicks, Bitly and Bl.ink are strongest. On UTM-specific reporting without manual tagging discipline, UTMLoop is the clear standout among these six. On multi-domain agency use, Rebrandly wins. On compliance and enterprise controls, Bl.ink is in a category of its own.
No single tool wins every category, which is the honest takeaway: pick based on which one or two criteria matter most for your actual use case rather than looking for a single best overall answer.
A practical way to test before committing
Build the exact same set of five to ten links across your top two candidates using your real upcoming campaign, not a hypothetical test case. Time how long it takes, check whether the naming stayed consistent, and pull a report a week later to see whether it actually answers the question your team asks most (which channel drove the most signups, not just which link got the most clicks).
If UTM-specific reporting is the deciding factor, our complete guide for UTM parameters is a good companion read before you commit to any of these six.
Frequently Asked Questions
Which of these six is cheapest at high volume?
Short.io generally offers the best price per link at higher volumes among these six, particularly because custom domains aren't a separate cost tier the way they are with Rebrandly or Bl.ink.
Which tool has the best out-of-the-box UTM reporting?
UTMLoop is built specifically around UTM parameters as the primary object, so campaign-level reporting is structured from the start rather than requiring manual tagging discipline the way Bitly, Dub, or Short.io do.
Is Bl.ink worth it for a small team?
Usually not. Its pricing and feature set are built for organizations with compliance requirements, like SSO and detailed audit logs. A small team without those needs will pay for enterprise features it doesn't use.
Do all six tools support custom domains?
Yes, though the tier at which custom domains become available varies. Short.io includes one free, while Bitly and Rebrandly generally require a paid plan before custom domains unlock.

Link rot happens when a shortening service shuts down or an account lapses, breaking every link it ever created, and a branded domain is the main defense.
