Cerbos's answer
Cerbos stands out in the crowded authorization landscape due to its innovative approach to managing roles and permissions. Unlike traditional systems that embed authorization logic within an application's core code, Cerbos introduces a standalone, self-hosted, stateless service, transforming intricate coding tasks into simpler configurations. This separation not only streamlines the authorization process but also reduces potential security risks and system bottlenecks.
Being open-source, Cerbos fosters a strong community backing, ensuring its evolution aligns with real-world developer needs. Its adaptability is evident in its support for multiple SDKs, YAML configuration, and dynamic context handling, which cater to a wide range of environments and use-cases. This flexibility is further enhanced by Cerbos Cloud, a premium solution offering advanced policy management tools.
Furthermore, Cerbos emphasizes transparency, allowing both technical and non-technical stakeholders to understand and modify the permissions structure. This democratization of authorization logic management reduces reliance on specialized coding expertise. Additionally, its commitment to robust security features, including audit logging and risk mitigation, ensures that businesses can trust Cerbos to safeguard their authorization processes.
In essence, Cerbos' unique blend of innovation, adaptability, community support, and security focus reshapes the way businesses approach and manage authorization, making it a game-changer in the field.
ViewForge's answer:
Three things. (1) Data ownership: ViewForge writes fitment as Shopify metaobjects native to your store — most competitors store fitment in their own database. (2) 8 verticals out of the box: auto, motorcycle, tractor, marine, power equipment, bicycle, printer, electronics — most competitors are automotive-only. (3) Smart Parse: extract fitment automatically from your existing product titles and descriptions instead of re-typing everything.
Cerbos's answer
Cerbos' primary audience is best described as forward-thinking engineering leaders at the helm of emerging startups, particularly within the FinTech and Software Development sectors. These leaders typically oversee small to medium-sized teams, with 5-20 engineers, in companies that have a workforce ranging from 0 to 100 employees. Their technological stack prominently features Kubernetes (k8s), indicating a modern and scalable infrastructure.
Financially, these companies are in their early growth stages, having secured funding between 0 to 10 million dollars, primarily in the Seed to Series A range. This suggests that they are in a phase of rapid expansion and are actively seeking solutions that can seamlessly scale with their growth.
The primary objectives of Cerbos’ users revolve around finding a reliable solution to their authorization challenges, ensuring that the chosen solution can be implemented without disruptions, and that it scales effortlessly as the company grows. In essence, the Cerbos champion is a visionary engineering leader, keen on adopting innovative solutions that align with their company's rapid growth trajectory.
ViewForge's answer:
Shopify merchants whose customers need to know whether a part fits before they will buy it — and who do not have an engineer on staff to build that themselves.
Concretely: auto and truck parts retailers, powersports and motorcycle dealers, tractor and agricultural parts sellers, marine and outboard suppliers, small-engine and power equipment stores, bicycle and e-bike component shops, printer supply merchants, and electronics accessory sellers.
Catalog sizes run from a few dozen products on the free tier up into the tens of thousands; it is running in production on a catalog of roughly 40,000 SKUs. The common thread is not the industry — it is that "does this fit my thing" is the question deciding the sale.
Cerbos's answer
Cerbos, co-founded by Emre and Charith, emerged from a vision to revolutionize the way authorization is approached in modern, cloud-native applications. The duo recognized a persistent challenge in software development: the immense time and effort developers invest in crafting and continually updating custom permissions. This repetitive cycle not only consumes valuable time but also diverts attention from the core essence of product development.
Driven by this realization, Emre and Charith embarked on a mission with Cerbos: to make the implementation of access-control as seamless and painless as possible. Their goal was to eliminate the need for repeatedly writing and rewriting custom permissions implementations. Instead, they envisioned a world where developers could channel their energies and creativity into building outstanding products that resonate with and delight their customers.
ViewForge's answer:
ViewForge came out of agency work. Normal View was building for a parts retailer running roughly 12,000 SKUs who needed fitment search, and every app we evaluated stored the merchant's compatibility data in the vendor's own database.
That is a strange trade when you look at it directly. Fitment data is genuinely expensive to produce — it is weeks of work — and the merchant would not own the result. It would belong to whichever app happened to be installed that year.
Shopify metaobjects made a different answer possible: write fitment as native structured data inside the merchant's own store. The theme reads it, the Storefront API queries it, Admin GraphQL exports it, and it is still there after an uninstall. That decision is what the rest of the app is built around.
Everything else came from real catalogs rather than a roadmap. Eight verticals exist because a tractor catalog is not Year/Make/Model. Smart Parse exists because that retailer had already written fitment into 12,000 product titles, and nobody was ever going to retype them.

Cerbos's answer
A person should choose Cerbos over its competitors for several compelling reasons:
Innovative Design: Unlike many competitors, Cerbos separates the traditionally embedded authorization logic from the application's core code. This standalone, stateless service simplifies authorization changes, converting intricate coding tasks into straightforward configurations.
Open-Source Flexibility: Cerbos' open-source nature ensures continuous evolution based on real-world feedback. This community-driven approach ensures that the product remains relevant and adaptable to changing needs.
Transparency and Inclusivity: Cerbos' structure allows a broader range of stakeholders, both technical and non-technical, to understand and modify the permissions structure. This democratizes the authorization process, reducing the dependency on specialized coding expertise.
Robust Security: Cerbos places a strong emphasis on security, offering features like audit logging and risk mitigation. This commitment ensures businesses can trust Cerbos to maintain the integrity of their authorization processes.
Flexibility and Control: Cerbos provides complete control over its deployment, scaling, and monitoring. Unlike solutions that are solely cloud-based or hardcoded, Cerbos strikes a balance between flexibility, control, and security.
Clear Value Proposition: Cerbos offers straightforward pricing and a user-friendly approach, contrasting with competitors that may have complex pricing structures or less intuitive systems.
Community and Support: As an open-source project, Cerbos boasts a strong community backing, ensuring users have access to a wealth of knowledge and support.
In summary, Cerbos' unique blend of innovation, flexibility, transparency, and security makes it a superior choice in the authorization landscape.
ViewForge's answer:
Data ownership. Fitment lives in your Shopify metaobjects, so uninstalling does not take your compatibility data with it. Convermax, EasySearch and PartFinder all keep it in their own databases, and getting it back depends on their export tooling on the day you cancel.
Cost at the low end. The search widget, the compatibility table on the product page and the saved-vehicle garage are all on the free tier, up to 50 products, with no expiry. EasySearch puts the table and the garage behind its $75/month Premium plan. Convermax starts at $250/month.
Automotive and non-automotive coverage. Eight built-in templates, and fully custom templates from $19/month, for catalogs that do not decompose into Year/Make/Model at all.
