2 Best Open Source Scrunch Alternatives in 2026

Notra is a Generative Engine Optimization (GEO) platform built for marketing teams and founders who want to know whether AI assistants recommend their brand when buyers ask for solutions. Instead of guessing, it runs your chosen prompts against ChatGPT, Claude, Gemini, and Perplexity with live web search enabled, then stores the full answers so you can see exactly what each engine said, where your brand appeared, and which competitors took the spots you didn't.

The dashboard tracks four core metrics:

Mention rate by engine shows what percentage of scans included your brand, your average list position, and how both have shifted since the last run.
Share of voice maps which brands get named when you don't, broken down per prompt, language, and engine. You add competitors and their common misspellings, and Notra handles the rest.
AI traffic attribution separates crawler fetches from genuine citations and human referrals. A bot indexing your site for training isn't the same as an assistant citing your page while answering a buyer, and Notra labels them differently across 66 known AI agents.
Content gaps surfaces the prompts where engines answer without mentioning you, ranked by how winnable each opportunity looks. Pick a gap and the built-in writer drafts a guide, listicle, or comparison using your brand identity, sitemap, and competitor data.

Every scan stores the complete engine response, not just a score. You can open any prompt, read the full answer, see which pages the engine cited, and even send a follow-up in the thread to test whether your recommendation survives a buyer pushing back.

Traffic tracking works without a script tag. It runs as middleware in Next.js, Nuxt, Astro, TanStack Start, or SvelteKit, and human traffic is dropped before anything is stored. Zero data retention is available as an add-on for teams with compliance requirements, restricting scans to model providers that support ZDR.

Plans are tiered by the number of AI answers tracked per month, starting at 2,000 on Starter and scaling to unlimited on Enterprise.

Tracks how often AI tools like ChatGPT, Claude, and Perplexity mention or cite your brand, then fixes the gaps through AEO strategy and content work.

Canonry is an AI visibility tracking platform built for businesses, marketing teams, and agencies that want to show up when AI tools answer buyer questions. It combines measurement with hands-on work: tracking which AI tools mention your brand, which competitors they name instead, and then addressing the gaps through Answer Engine Optimization (AEO).

The platform monitors ChatGPT, Claude, Gemini, Perplexity, Copilot, Grok, Meta AI, and DeepSeek. Scheduled checks record whether each tool names your brand, cites your site, or leaves you out entirely, alongside the competitors it surfaces. Server logs track AI bot visits and traffic from people who follow AI-generated links, giving you both answer-level and traffic-level data.

Canonry offers four distinct products:

Canonry Custom tracks AI search results for each location or market under a single domain, useful for franchise teams and multi-market brands.
Canonry Embedded lets agencies add a client's AI visibility report to their existing portal via a single iframe, with no SDK or private keys required.
White-label AEO puts Canonry's team behind an agency's brand, handling research, fixes, tracking, and client reports while the agency owns the client relationship.
Canonry Managed is a fully done-for-you service for businesses and marketing teams, covering AEO strategy, content, structured data, business detail consistency, and reporting.

The AEO work itself goes beyond adding schema markup. It covers structured data (JSON-LD for business info, services, and FAQs), consistent business details across third-party sources like Google Business Profile and Wikipedia, bot access configuration, and content that directly answers buyer questions. Canonry also offers a free site check covering 16 on-site factors.

For agencies running paid search, Canonry Ads (private beta) surfaces buyer questions, competing brands AI names, and ideas for ChatGPT Ads tests, while leaving strategy and spend decisions with the advertiser. Tools like Otterly.AI, Peec AI, and AthenaHQ occupy similar ground, but Canonry pairs tracking with a managed service layer that handles the actual optimization work.
