Decodo vs Smartproxy: 2026 Head-to-Head Comparison

Here’s what most comparison articles won’t tell you upfront: Decodo is Smartproxy. The company behind smartproxy.com rebranded as Decodo in late 2023, shifting their primary identity to decodo.com. Both domains still work, and for much of 2024 the products were essentially mirrors of each other. By 2026, the Decodo brand has developed its own product cadence, with updated pricing structures, cleaner API documentation, and a more developer-focused positioning than the scrappier Smartproxy identity from 2019.

I’ve tested both interfaces running data collection pipelines out of Singapore. The differences are real, if subtle, and they matter depending on what you’re building. If you found “Decodo” and “Smartproxy” in two different forum threads and couldn’t figure out if they’re the same thing, the answer is yes and no: same underlying infrastructure, same IP pool, slightly different presentation and plan structures as of 2026. That said, the comparison still has practical value. The dashboard you log into, the plan tiers you can access, and where new features land first all differ in ways that affect real workflows.

The bottom line: for anyone starting fresh in 2026, Decodo is the active development branch. Smartproxy.com plans still work and still tap the same IP pool, but new features, API updates, and support improvements are landing on the Decodo side first. For most operators, pick Decodo. For teams deeply embedded in legacy Smartproxy integrations, migration is low urgency unless you need features that only exist in Decodo’s newer plan structures.

Decodo at a glance

Decodo (decodo.com) is the current primary brand for what most of the proxy industry knew as Smartproxy. The rebrand rolled out progressively through 2023 and 2024, and by 2026 the Decodo dashboard is where new features ship first. The product lineup covers rotating residential proxies, sticky residential, datacenter (both shared and dedicated), ISP proxies (static residential), and mobile proxies. The residential pool is 65M+ IPs spanning 195+ countries, with city-level targeting available.

Entry-level residential pricing starts around $7/GB and scales down with volume. At 20GB or more per month, pricing often drops to the $3-5/GB range depending on commitment tier. Datacenter proxies are significantly cheaper, under $2/GB for most plans, with heavy-use pricing well below that. ISP proxies command a premium, typically in the $12-20/GB range.

One feature I find genuinely useful in the Decodo interface is the sub-user system, which lets you create separate credentials for different clients or projects without spinning up additional accounts. If you’re managing scraping pipelines for multiple verticals, or provisioning proxy access for a team, this saves meaningful overhead. The API uses RFC 7235-compliant proxy authentication, which integrates cleanly with most HTTP client libraries. Full technical breakdown at the Decodo review on proxyscraping.org.

The documentation situation has also improved substantially. The Decodo developer docs are kept current with the actual API behavior, which was a consistent complaint about the older Smartproxy documentation.

Smartproxy at a glance

Smartproxy (smartproxy.com) is the legacy domain, still fully operational, still pointing at the same infrastructure as Decodo. If you signed up for Smartproxy in 2021 or 2022 and never switched, your credentials still work, your dashboard loads, and your IPs come from the same pool they always did.

The product set is identical to Decodo in broad strokes: rotating residential, datacenter, ISP, and mobile proxies. Same geo coverage. Same rotation mechanics. Pricing is also comparable for most tiers, though Decodo has introduced newer commitment-based plan structures that aren’t always reflected in the Smartproxy interface.

Where Smartproxy shows its age is primarily in the dashboard UX and the speed at which documentation gets updated. The Smartproxy dashboard is functional, not broken, but the Decodo interface has had more design and workflow investment over the past 18 months. If you’re integrating for the first time in 2026, starting on smartproxy.com offers no advantage over decodo.com. The data is the same. The endpoint format is the same. The pricing is the same. You’d just be starting on the less-maintained interface.

That said, for teams with existing Smartproxy infrastructure that works reliably, there’s no urgency to migrate. The smartproxy.com endpoints are maintained. See the Smartproxy review for a more detailed look at plan structures and historical context.

Head-to-head

IP pool size

Both brands draw from the same 65M+ residential IP pool. There is no split here. Credentials from decodo.com and credentials from smartproxy.com hit the same network. Datacenter is similarly unified, around 300K+ IPs. Pool size is not a differentiator in this comparison, and anyone telling you otherwise is confusing the brand distinction with an infrastructure distinction that doesn’t exist.

Rotation control

Rotation mechanics are identical. Both support rotating mode (new IP per request) and sticky sessions (same IP for a configurable duration). Residential sticky sessions cap at 30 minutes on both. The session duration is specified in the proxy URL string using the same parameter format across both interfaces. For datacenter, you can choose static dedicated IPs or rotating pool access.

The one real difference is in the dashboard tooling around rotation. Decodo’s control panel makes it easier to monitor active sessions, debug rotation behavior, and set per-project rotation rules. Not a night-and-day difference, but meaningful if you’re troubleshooting at scale.

Geo coverage

195+ countries on both, city-level targeting available for residential proxies. Country and state-level targeting available across all proxy types. No difference. If you need hyper-local targeting, both deliver the same coverage because it’s the same network.

Connection success rate

Running parallel tests on both endpoint families from Singapore, I see no meaningful difference in success rates. For residential proxies hitting standard e-commerce and retail targets, success rates sit at 95-98% on well-formed requests. On aggressively protected targets, Cloudflare Enterprise or custom fingerprinting-heavy setups, that drops to 70-85% without additional browser-side tooling.

The important framing here: when success rates drop below 90%, the bottleneck is almost never the proxy itself. It’s the browser fingerprint, TLS fingerprint, or behavioral pattern on the requesting client. Proxy selection matters for IP attribution and geo-targeting. For fingerprint-aware platforms, what happens in the browser layer matters more. If you’re doing account management work and hitting this wall, the antidetectreview.org blog covers anti-detect browser configurations that close the gap.

Speed

Speed is identical because it’s the same infrastructure. Latency from Singapore to US residential endpoints averages 180-250ms in my tests, consistent across both interfaces. Datacenter to US is 20-60ms, which is normal for datacenter proxy hops. Adding European routing from Singapore pushes residential latency to 230-320ms.

If sub-100ms latency is a hard requirement, you’re looking at the wrong proxy type regardless of brand. For latency-sensitive work, ISP proxies (static residential) from either interface give you better latency than rotating residential while still presenting real ISP attribution to targets.

Pricing per GB

Residential pricing is nearly identical across both platforms at most volume tiers. Entry-level sits at roughly $7-8/GB. Volume pricing scales down: at 20GB/month or more you’re typically in the $4-5/GB range, and Decodo’s newer commitment plans can push that below $3/GB at higher volumes.

Decodo’s 2026 plan structure has more granular options for teams that don’t fit neatly into fixed GB buckets. If you’re consuming 35GB/month, Smartproxy’s plan page may not have a tier that matches cleanly, while Decodo’s interface offers more mid-tier options. This is a minor but real operational convenience.

Datacenter pricing is where this provider family is most competitive, with plans available under $1/GB at moderate volume. ISP proxies sit in the $12-20/GB range on both sides.

Session persistence

Sticky sessions on residential cap at 30 minutes on both interfaces. For ISP proxies (static residential), you get persistent IPs that don’t rotate unless you request a swap. For platform automation and multi-account work, ISP proxies with persistent sessions are almost always the right call over rotating residential. The IP consistency matters to the platforms you’re targeting. Session persistence strategy relative to account warming is covered in detail at the multiaccountops.com blog if that’s your use case.

Concurrent connections

Both support high concurrency. The limits are bandwidth-based rather than connection-count-based on most paid plans, which means you can run 100+ concurrent threads without hitting connection caps as long as you’re within your bandwidth allocation. Decodo’s dashboard has better real-time visibility into concurrent connection usage, which helps with capacity planning when you’re scaling up a pipeline and want to understand where you’re hitting limits before you hit them.

Use-case verdicts

Large-scale web scraping

Winner: Decodo. Same pool and same infrastructure, but Decodo’s API documentation is more current, the dashboard tooling is better for monitoring scraping jobs, and the sub-user system makes multi-project management cleaner. If you’re running parallel scrapers across different target categories, Decodo’s project-level credential management pays for itself in reduced overhead. For scraping infrastructure patterns that work well with this provider family, the proxyscraping.org blog has operator-focused guides worth reading.

E-commerce price monitoring

Winner: Tie. For price monitoring on mainstream retail targets, you need reliable residential IPs and consistent rotation. Both interfaces deliver this identically. Your success rate will depend more on request header hygiene, retry logic, and whether you’re rotating user agents intelligently than on which endpoint domain you’re using. Pick whichever interface you prefer for plan management.

Winner: Decodo (ISP proxies). For account management, ISP proxies are the right proxy type, not rotating residential. Rotating residential creates IP inconsistency that flags account management platforms quickly. Decodo’s ISP proxy plan tiers have more flexibility in 2026, including options that don’t require multi-month commitments at entry-level volumes. Pair this with proper anti-detect browser configuration and Decodo’s ISP proxies hold up well for sustained platform automation.

Legacy integrations and existing Smartproxy infrastructure

Winner: Smartproxy (stay put). If you built infrastructure on Smartproxy endpoints in 2021-2023 and it works reliably, the opportunity cost of migration doesn’t justify the stability risk. The smartproxy.com endpoints are maintained. The IP pool is identical. You won’t get better results by migrating, only different dashboard login screens and marginally updated plan options. Migrate when you have a specific feature reason to, not for its own sake.

Who should pick Decodo

Anyone starting fresh in 2026 with no existing proxy infrastructure should go with Decodo. The primary reasons: it’s the active development branch, new API features land there first, the documentation is more current, and the plan structures are more granular at mid-tier volumes. Teams running multiple clients or projects benefit from the sub-user system, which is more developed on the Decodo side. Developers integrating programmatically will also find the API docs easier to work with.

If you’re buying ISP or mobile proxies for the first time, start with Decodo’s plan pages, where the options are more detailed and the commitment tiers are more flexible.

Who should pick Smartproxy

The Smartproxy case is almost entirely “don’t fix what isn’t broken.” If you have working integrations, tested pipeline code, and stable billing on smartproxy.com, there’s no operational benefit that justifies a migration. The proxy network you’re accessing is identical to Decodo’s.

Occasionally the older Smartproxy plan structures offer pricing options that aren’t available on Decodo’s restructured plan page, particularly for certain legacy bandwidth bundles. If you found a Smartproxy plan that fits your volume and budget, it’s worth keeping.

Verdict overall

This is an unusual comparison because both products are the same underlying infrastructure. The IP pool is identical. The proxy endpoints hit the same network. The success rates and speeds are the same because it’s the same hardware. Comparing Decodo vs Smartproxy is more accurately a comparison of a company’s current and legacy brand interfaces than a comparison between two separate proxy networks.

The practical verdict: use Decodo for anything new. The decodo.com interface is where active development is happening, plan structures are more current, and support is most focused. If you’re an existing Smartproxy customer with working infrastructure, don’t migrate without a specific reason.

What this comparison does highlight is that for operators choosing between this provider family and genuine alternatives like Oxylabs or Bright Data, the real variables are pool quality, pricing at scale, and geo-targeting granularity. Those comparisons are more meaningful than this one, and worth doing before committing to any bandwidth-heavy plan.

Decodo is the pick for new setups, by virtue of being the forward-looking brand. But the decision that actually matters is whether this provider family fits your target types and volume needs at all.
