Free Sistrix Alternative: 6 Best Tools in 2026

🔬 How I picked these free Sistrix alternatives

I only kept tools that replace a Sistrix feature for $0, with no card and no time limit. ChatSEO is the one exception: it is a paid tool with a free trial, and I flag it because I co-founded it.

Every free limit and price below was checked on the vendors' official pages on October 27, 2026. I took Sistrix's Start plan apart (the Visibility Index, competitor research, keyword research, backlinks and the on-page crawl) and looked for the best free tool for each piece.

My take after years of SEO for clients: a visibility index is a trend line, not traffic. It scores a domain on a fixed keyword set, weighted by position and volume, so it is great for spotting a Google update hit or a competitor's rise, and poor at telling you what your own site earns. For your own site, your Search Console clicks are the truth. Use the free tools below for the rest.

📊 Free Sistrix alternatives compared

🏆 The 6 best free Sistrix alternatives

1. SISTRIX free tools: the Visibility Index without a plan

The best free Sistrix alternative is part of Sistrix itself: its free Visibility Index Check shows the visibility of any domain on Google, with no signup. The same free tools page adds a Google Update Check (was your domain hit, and how hard), a Keyword Tool with related terms and questions, and SISTRIX Smart for a free on-page check.

Use it to read a trend, not a number. A drop that lines up with a dated Google update tells you where to look. A flat line on a small site often only means the keyword set does not cover your niche, which is common outside Germany and the big markets.

2. Semrush Free: competitor research for $0

Semrush's free account replaces Sistrix's competitor research for occasional checks: 10 reports a day across its main tools, with no card. You get a domain's estimated traffic, its top keywords and pages, and its backlinks, as listed on Semrush's pricing page.

Ten reports go fast, so plan them: one domain overview, one keyword list, one backlink report per competitor. The paid SEO plan is $139 a month, so the free tier is for a monthly look, not a daily one. Our free Semrush alternative guide lists the other free options.

3. Google Search Console: your own visibility, with real data

Google Search Console replaces Sistrix for your own site, with better data: the real clicks, impressions and positions of every query, not an estimate from a keyword sample. It keeps 16 months of history, against 3 months on Sistrix's Start plan.

Read a position only with an exact page and an exact query as filters. The site-wide average mixes thousands of queries, and an impression at position 85 is not a view. Our guide to analyzing a website's SEO shows the filters step by step.

4. Ahrefs Webmaster Tools: free backlinks and site audit

Ahrefs Webmaster Tools, now sold as Ahrefs Free, replaces Sistrix's link data and on-page crawl on sites you own. It shows the backlinks pointing to your verified sites and runs a Site Audit with 170+ technical and on-page checks, with 5,000 crawl credits per month per project, against 30,000 URLs a month on Sistrix Start.

The limit is ownership: you must verify each site, so it does not work on competitors. For a competitor's links, Semrush's free reports or our free Ahrefs alternative guide cover the other options.

5. Google Keyword Planner: free keyword research

Google Keyword Planner is free inside a Google Ads account, and it replaces Sistrix's keyword research with keyword ideas straight from Google. You do not have to run a campaign to use it.

Without active ad spend, it shows volume ranges (1K to 10K) instead of exact numbers. That is enough to rank ideas against each other and pick the search intent to target, which is the decision that matters.

6. ChatSEO: best for deciding what to do with competitor data

ChatSEO is the tool I co-founded, and it is not free: the onboarding and your first message cost nothing, then it is a 7-day trial with 30 credits (card required, nothing charged before day 7). After the trial, plans start at $29/month, or $23.20/month billed annually.

It answers the question a visibility chart leaves open: which keywords and pages to work on next. It compares your site with your competitors on live keyword and backlink data, reads your Search Console to find the pages losing clicks, and returns a prioritized list. Do not pick it for a visibility index, a 10-year history or a full crawl of a large site: Sistrix does that, and ChatSEO checks pages one by one.

💸 What Sistrix costs, and what you really pay for

Sistrix has no free plan: after a 14-day free trial, Start costs €119 a month (about $133), plus tax. Start covers 1 user, 3 projects, 30,000 crawled URLs a month, 3 months of data history and 2,500 SERP updates. Plus is €239 a month (about $267) with 3 users and 5 years of history, Professional €419 (about $469) and Premium €799 (about $894). Sistrix bills in euros, every plan cancels monthly, and an annual contract lowers the monthly price.

What you pay for is the history and the scale: years of visibility data on any domain, for many markets. That is worth it for an agency or an in-house team watching many competitors. For one site, the free tools above answer the same questions, and none of them, Sistrix included, tells you which page to fix first.
