UnderPeaks

Underpeaks is a developer-first headless CMS that generates production-ready Flutter and Next.js applications from a single content model. Define your data model once, and Underpeaks generates real, readable source code for both a mobile app and a web app — not scaffolding, not a black box. The platform supports five database backends (Supabase, PostgreSQL, MySQL, MongoDB, and Firebase) through one consistent adapter layer, so teams aren't locked into a specific database vendor. Underpeaks is available as Underpeaks Core, a free, self-hosted, open-source option that runs on a team's own infrastructure, or as Underpeaks Studio, a fully managed hosted platform with additional collaboration and deployment features. Underpeaks is built for developers and agencies who need to ship both a mobile app and a web app from the same data model without maintaining two separate backends or duplicating business logic.

viingx

viingx is the Marketing Content Hub that unites Digital Asset Management (DAM), Product Information Management (PIM), and headless content delivery in one platform. With more than 1,200 connectors and an API-first architecture, viingx sits at the center of the marketing technology ecosystem. Marketing teams use it to aggregate, enrich, organize, and deliver every type of content, from images, videos, and documents to complex structured product data, across all channels from a single system. viingx was built as the modern alternative to traditional DAM, MAM, PIM, and multi-domain content management systems. Before founding viingx in 2019 in Lucerne, Switzerland, the founders spent many years building and implementing the censhare omnichannel content platform for enterprises worldwide. That experience shaped a clear conviction. Marketing teams do not need heavier enterprise systems. They need a lightweight, flexible platform that delivers enterprise-grade content capabilities without monolithic architecture, months of implementation, or permanent consulting dependency. What viingx is used for: Digital Asset Management (DAM): One central repository and single source of truth for every digital marketing asset, including images, videos, texts, templates, brand guidelines, and product data. Teams find any asset in seconds thanks to fast search, version control, and granular permissions. Product Information Management (PIM): Structured product data of any complexity, managed centrally, linked to the matching media assets, and delivered consistently to every sales channel, from e-commerce and web to print and marketplaces. Marketing Content Hub: viingx breaks down content silos and connects content sources and marketing channels into one seamless ecosystem. Planning, creation, review, and publishing happen in one place. Headless CMS: Content is managed media-neutrally and delivered via API to websites, online shops, and apps. Created once, reused across brands, regions, and use cases. Marketing production automation: Templates for print and digital fill themselves with current content. Regional and language variants of entire campaigns are generated in minutes, not days. Key capabilities: No-code configuration: Content types of any complexity, workflows, input masks, and language variants are set up through the graphical interface. The marketing team implements new requirements itself, without developer support. 1,200+ connectors: Ready-made integrations for e-commerce platforms, CRM systems, marketing automation, CMS, and creative tools, plus a well-documented API for everything else. Collaboration workflows: From creation to approval, teams, agencies, and partners work with clear responsibilities and transparent asset statuses. Feedback happens directly in the system, no file downloads required. AI-assisted content work: Built-in AI tools take over recurring tasks such as image creation and content optimization, freeing the team for creative work. SaaS delivery: Automatic updates, no local operation costs, and a simple, transparent pricing model that scales from small teams to large organizations. Who viingx is for: viingx is built for marketing teams, content managers, and brand managers in mid-sized companies and enterprises. It replaces fragmented tool landscapes and complex legacy platforms such as traditional DAM and PIM suites and universal content hubs. Typical evaluation contexts include the search for censhare alternatives, Pimcore alternatives, or a unified replacement for separate DAM and PIM systems. The result is faster time-to-market for campaigns, lower content operations overhead, and a team that spends its time on creative work instead of routine tasks. Onboarding takes days rather than months, and viingx delivers value from week one.
