Credits or fixed quotas: which model keeps your AI visibility costs predictable?
Rankscale and growResonance both track how AI search systems talk about your brand, and both are built in the DACH region. The key difference is how you pay: Rankscale bills in credits, while growResonance gives each plan a fixed number of prompts and answers. This comparison shows which model is easier to budget for and when each tool is the better fit. On top of that, growResonance is open source: self-host it with your own API keys or use the hosted version.

Why teams choose growResonance over Rankscale
Most teams start by asking about data quality. Budget planning raises a second question: what will monitoring cost next quarter when new prompts, locations or clients are added? growResonance answers it with five pillars:
- Open source
- Fixed quotas
- Interface-based tracking
- Tasks, not just metrics
- Built for agencies in the EU
1. Open source: pay for the API, not for conversions
growResonance's source code is public on GitHub under AGPL-3.0. When you self-host, the software is free. You add your own API keys and pay providers directly for each query, with no credits to translate into answers. Your data stays on your own infrastructure, and because the code is open, you can verify exactly how tracking works. There is no lock-in: you can move between self-hosting and the hosted version at any time. If you would rather not run a server, the hosted version runs in the EU, in Frankfurt. The documentation lists which features are included when you self-host.
2. Fixed quotas, no conversion math
Every growResonance plan states three numbers: prompts, models and a monthly answer cap. Growth includes 150 prompts, three models, daily tracking and up to 13,950 answers. You never need to work out how many credits a run will consume. Once the quota is reached, tracking pauses until the next cycle while your data and reports stay available. Failed queries are credited back.
3. Measured the way your customers ask
growResonance asks ChatGPT, Gemini and Google AI Mode your audience's questions every day through the models' user interfaces, not their APIs. You see the answers your customers see, including position, cited sources and the sub-queries ChatGPT runs for a question (query fan-out).
4. From data to tasks
Each run produces prioritised tasks. The agent knows your workspace data, suggests prompts, tasks, articles and reports, and only creates them after you approve. Once a task is done, growResonance shows how the affected prompts develop.
5. Built for agencies in the EU
Agency plans include a cross-client overview, white-label reports without growResonance branding and a data processing agreement under Art. 28 GDPR. Data is hosted in Frankfurt, and support is available in German.

growResonance vs. Rankscale: feature comparison
Billing: credits vs. quotas
With Rankscale you buy a monthly credit budget. Its pricing page says 1,200 credits on Pro equal up to 4,800 answers, and 5,500 credits on Growth up to 22,000 answers. Unused credits can roll over: up to 2x on Pro and Pro+, up to 3x on Growth and Enterprise, none on Essentials. That flexibility helps when demand varies from month to month.
growResonance counts fixed prompts and a fixed answer cap. The answers per prompt follow from three models and daily tracking, so each prompt uses the same share of your quota every month. Teams that must sign off a fixed monthly budget will find this simpler. Teams with highly variable workloads may benefit more from Rankscale's rollover.
Coverage: three interfaces vs. 17+ engines
Rankscale lists Google AI Overviews and AI Mode, ChatGPT, Perplexity, Gemini, Claude, Copilot, DeepSeek, Grok and Mistral among others, and speaks of 17+ engines with no per-engine upsell. It also covers 240+ regions and languages. If you need to watch many engines or countries at once, Rankscale offers the wider range.
growResonance tracks ChatGPT, Gemini and Google AI Mode daily through their interfaces, with Claude and Perplexity coming soon. The range is narrower, but every answer appears as users see it, with position, sources and sub-queries.
Analysis: competitors, sources, sentiment
Analyse competitors and sources
Both tools analyse competitors, citations and sentiment. According to its website, Rankscale lets you slice sentiment by brand, topic and model and calculates an AI visibility score.
growResonance reports visibility, share of voice, average position, sentiment from 0 to 100 and rank per model, location and week. Source analysis groups cited pages by type, such as trade press, user-generated content, your own site or competitors. Sentiment shows the original sentences, most critical first.
Optimisation: audit, agent and content
Technical audit and content audit
Rankscale runs page audits on AI readiness, AI bot crawlability, site hierarchy and technical SEO, with monthly allowances per plan (Pro: 50 audits).
growResonance's technical audit checks AI bot access in robots.txt, llms.txt, structured data and load time, and gives a fix prompt for every finding. The article assistant writes articles from AI answers and the Google top 10, with fact-checking and a content score. Existing pages can be improved automatically, and any article can become a social media carousel.
Reporting and agencies
Rankscale explicitly targets agencies. Its Growth plan includes white-label dashboard links with API access, a commission-based partner programme and a listing in its agency directory.
growResonance delivers reports as slides, PDF or link in your logo and colours, without growResonance branding on agency plans. Links can be password-protected and expire after 7, 30 or 90 days. You can also build pitch decks for prospects.

As of October 29, 2026. growResonance prices are net, in euros per month. Rankscale prices per rankscale.ai/pricing, in US dollars per month, billed monthly or annually. Currencies are not converted. Rankscale answer counts are maximums ("up to") per its pricing page.
Example 1: about 4,700 answers a month
A team wants to track about 50 questions a day across three AI systems, roughly 4,500 answers a month.
- Rankscale: This fits Pro, with 1,200 credits and up to 4,800 answers, at $99 monthly or $84 billed annually.
- growResonance: This fits Start, with 50 prompts and up to 4,650 answers, at €25 cancel-monthly or €20 on a 12-month term.
Rankscale lets you choose from more engines and set up to 10 brand dashboards. growResonance ties the answer count to a fixed 50 prompts.
Example 2: an agency with 10 clients
An agency manages 10 brands and needs white-label reports.
- Rankscale: White-label dashboard links start on Growth, at $385 monthly or $327 annually, with up to 22,000 answers and 50 brands. Pro covers 10 brands but has no white label and up to 4,800 answers.
- growResonance: Agency includes 10 client workspaces, a pool of 450 prompts, up to 41,850 answers and white-label reports for €195 monthly or €165 on 12 months.
If you need far more than 10 brands or many engines per client, Rankscale Growth is the better-sized plan.

What is a credit in Rankscale?
A credit is the unit Rankscale uses to bill tracking runs. Its pricing page says 1,200 credits on Pro produce up to 4,800 answers a month. How many answers you actually get depends on your setup. Depending on the plan, part of your unused credits can roll over to the next month.
Which pricing model is easier to plan?
Fixed quotas are easier to budget because every prompt uses the same amount each month. Credits are more flexible when your needs change often, and Rankscale's rollover cushions quieter months. The deciding factor is whether you must approve a fixed amount or need room for fluctuation.
Which tool works better for agencies?
Both serve agencies. Rankscale offers white-label dashboard links, a partner programme and up to 50 brands from its Growth plan. growResonance has dedicated Studio and Agency plans for 5 or 10 clients, with a cross-client overview, white-label reports as slides, PDF or link, and an Art. 28 GDPR agreement.
Is growResonance open source?
Yes. The source code is public on GitHub under AGPL-3.0. You can run growResonance on your own server, review the code and adapt it to your workflows. If you would rather not handle operations and updates yourself, you can book the hosted version instead, with servers in Frankfurt.
How much does self-hosting cost?
The software itself is free. You pay only for your server and for the queries you send to AI providers through your own API keys. Unlike a credit model, that means paying directly for actual usage, with no conversion step. Your API costs depend on how many prompts, models and runs you set up.
Can I try growResonance before buying?
Yes. The free visibility check shows, without sign-up, how ChatGPT, Gemini and Google AI Mode mention your brand. You can then pick a plan; Start costs from €20 a month on a 12-month term.
