Familiars.io is an indie adventure RPG released in 2020 on multiple platforms, developed by a small creator. While it has some cult following due to its similarities to classic Pokémon-style games and was notable when launched for being a lightweight online creature collector, its player base has remained small. Most indie browser RPGs of this style outside major platforms rarely sustain large daily numbers long-term, especially four years after release without ongoing active marketing or major updates.
