As answered by people managing Mattermost and Wernelo.
Wernelo's answer:
Wernelo brings community, creator, project, website, and live-stream discovery together in one platform.
Instead of focusing on just one type of content, Wernelo offers multiple ways to discover what's happening online:
Wernelo's goal is to make online discovery more connected, helping people find interesting communities and projects while giving creators another place to build visibility.
Wernelo's answer:
Wernelo offers a broader discovery experience by bringing several types of online content together in one place. Rather than using separate platforms to find Discord communities, discover projects, explore creator content, and browse live streams, users can explore these experiences through Wernelo.
It's designed for both sides of discovery: people looking for something new and creators or community owners who want to showcase what they're building.
Wernelo is continuously evolving, with a focus on accessible discovery, community participation, and helping worthwhile projects reach new audiences.
Wernelo's answer:
Wernelo is designed for online communities, content creators, indie developers, website owners, project builders, streamers, and people who enjoy discovering new things online.
Its audience includes Discord server owners looking to showcase their communities, independent creators wanting to share their work, Twitch and Kick streamers looking for additional visibility, and everyday users searching for interesting communities, projects, websites, and live content.
It's particularly relevant to people building online projects and communities who want another way to connect with an audience.
Wernelo's answer:
Wernelo began as PromoHub, a platform focused on helping people discover and promote Discord communities.
As the project developed, its vision expanded beyond server promotion. The platform grew to include a discovery Hub for creators and projects, a Discord Server Directory, and Live discovery for Twitch and Kick streams.
Eventually, the original name no longer represented the broader direction of the platform. The decision to rebrand as Wernelo was about creating an identity that better fits the long-term vision: a place where people can discover communities, creators, websites, projects, and live content.
Wernelo represents the next chapter of that journey. The underlying goal remains the same: help people discover worthwhile things online and give creators and community owners more opportunities to showcase what they build.
Today, Wernelo continues to evolve as an independent project with a broader focus on online discovery.
Wernelo's answer:
Wernelo is built using a modern web technology stack, The platform also includes a custom Discord bot that connects community promotion features with the website.
Wernelo's answer:
Wernelo is an evolving discovery platform serving online communities, independent creators, developers, streamers, and project owners. Rather than highlighting individual customers, the platform focuses on helping a broad range of communities and creators showcase their work and become easier to discover.
