3 Best Ahrefs Alternatives in 2026

Ahrefs is the SEO suite built around the industry's reference backlink index, sold as seat-based subscriptions. Here is the shortlist worth your time, compared on verified pricing, coverage, and the catch each vendor’s own page will not tell you.

The best Ahrefs alternative depends on the job. For daily hands-on SEO work, Semrush is the closest like-for-like suite swap, and Similarweb goes deeper on audience and market intelligence. For backlink, keyword, or authority data inside your own product or scripts, 1Lookup returns the same categories of data as flat-priced API lookups with no suite subscription.

Disclosure: this site is built by 1Lookup. It appears on this list where it genuinely fits, and we say plainly when a competitor is the better choice.

Why teams look beyond Ahrefs

No per-lookup or standalone API pricing: API v3 access requires at least the $129/mo Lite suite subscription, so light programmatic users pay for a full SEO toolset they may not use
API allowances are modest for programmatic volume: every billable request costs at least 50 units, so Lite's 100,000 units support at most 2,000 requests/mo, and Lite caps responses at 100 rows per request (Standard 250, Advanced 500)
Overage pricing for additional API units is not publicly listed - on plans that allow pay-as-you-go charges, extra units are auto-charged with no published per-unit rate, PAYG purchases expire after three billing months, and Ahrefs 'does not issue refunds in general'
Three separate 'credit' systems (API integration units, Site Audit crawl credits, and in-app report credits on Starter/Lite) with different limits; Lite users also face per-user in-app credit caps (1,000/mo) and $40/mo per additional user (max 2 extra)
No free trial and no discounts by stated policy; the free tier only covers sites you verify ownership of, so competitor analysis requires a paid plan; Enterprise requires an annual commitment

These are factual scope and pricing characteristics, not knocks; Ahrefs remains the right tool for the buyers described in the verdict section below.

The shortlist, in order

1. 1LookupOur product

Best pay-per-lookup SEO data: backlinks, keywords, and authority by API

Pick 1Lookup when you need backlink profiles, keyword metrics, or domain authority programmatically and want per-lookup pricing on shared credits instead of a monthly suite subscription with unit allowances.

Starting price: $99/mo for 20,000 credits ($4.95 per 1,000, down to $2.00 on Enterprise)
Free option: Free single lookups via the online tools at 1lookup.io/tools, no account required
The catch: Younger brand with a smaller public review footprint than long-established incumbents

2. Semrush

Best like-for-like suite swap with a broader marketing toolset

Pick Semrush when you want the closest replacement for daily Ahrefs workflows (rank tracking, audits, keyword research) plus content, advertising, and AI-visibility tooling in the same subscription.

Starting price: $139/mo for the entry "SEO" plan (5 websites to monitor, 500 keywords tracked daily; $117.33/mo billed annually). API access requires the $549/mo Advanced plan ($455.67/mo billed annually), with API units purchased separately on top.
Free option: Free plan at $0/mo: '1 demo project', '10 reports per day across all vital tools', AI Visibility features; no credit card required. Semrush's own blog details the free limits further: 10 queries/day on analytics reports, 10 tracked keywords in Position Tracking, 100 URLs/mo in Site Audit. No free API access.
The catch: No contact-data products: Semrush sells SEO and market analytics, not email addresses, phone numbers, or IP intelligence

3. Similarweb

Best for audience and market intelligence beyond the link graph

Pick Similarweb when your competitive questions are about traffic, audiences, and industries rather than backlinks, and you want panel-based market data alongside basic SEO metrics.

Starting price: $125/mo billed annually (or $199 month-to-month) for the Web Intelligence "Competitive Intelligence" plan: 1 user, 3 months of historical data, worldwide view only. Sales Intelligence "Individual" is $99/mo billed annually ($129 monthly, "1 user (1,000 credits)"); the standalone AI Search Intelligence (AEO) plan is also $99/mo billed annually ($129 monthly, 1 user, 150 tracked prompts).
Free option: Free similarweb.com account with high-level website/app lookups - the packages-page FAQ calls the free data "a very high-level taste" of the platform, with no numeric limits published on current pricing pages. Separately, a free DigitalRank API tier gives 100 data credits/month for global website-rank lookups (per Similarweb's own knowledge-center article; that article blocks direct fetches, see notes).
The catch: All self-serve plans are single-user (1 seat); any multi-user setup requires a custom-priced Business/Enterprise package via sales

Who should choose what

1Lookup: Best pay-per-lookup SEO data: backlinks, keywords, and authority by API.
Semrush: Best like-for-like suite swap with a broader marketing toolset.
Similarweb: Best for audience and market intelligence beyond the link graph.

Migration effort

Suite-to-suite moves (Ahrefs to Semrush) mean re-creating projects, tracked keywords, and audit schedules; both sides import keyword lists by CSV, so budget an afternoon rather than a sprint. Moving to API-based data is a different shape entirely: you wire endpoints for the specific metrics you need and stop paying for the dashboard.

Ahrefs alternatives FAQ

What is the best Ahrefs alternative?

For running SEO campaigns day to day, Semrush is the closest replacement and the usual head-to-head choice. For market and audience intelligence, Similarweb. For getting backlink counts, keyword volumes, or authority scores into your own tools, a per-lookup data API such as 1Lookup avoids paying for a whole suite.

Is there a cheaper way to get Ahrefs-style data by API?

Ahrefs' API v3 is included from its Lite plan upward, which is priced as a full SEO suite, and every billable request draws down monthly units. If your usage is a stream of individual lookups rather than daily suite work, per-lookup pricing usually comes out cheaper; the comparison table above shows the verified numbers side by side.

Does any alternative match the Ahrefs backlink index?

Ahrefs' crawler and index are the product's core moat, and its Domain Rating is a de facto industry metric. Semrush maintains its own large index, and third-party studies disagree about which is bigger on a given day. If your work is deep link-graph analysis, shortlist the two suites; if you need summary backlink data per domain, per-lookup APIs cover it.

When is Ahrefs itself the right choice?

When someone on the team is in an SEO tool every day: agencies, in-house SEO teams, and content teams doing serious keyword research. Its free Webmaster Tools tier for verified sites is also genuinely useful. The alternatives here win when the need is programmatic data or market intelligence, not daily suite work.
