PLAY FREE Bulbasaur in PokeIdle: Which Stone, Which Level, Which Version
The query asks for a stone. The honest answer is a version table, because net never asks for one.
The starter people expect a leaf stone for
Catalog row for World and io: hunt level 20, about 248 XP, NPC sale 3,000, base total 318, the highest of the three starters in that snapshot (Squirtle 314, Charmander 309). That is a reason to consider Bulbasaur. It is not a gym win-rate.
Net starters come from Pallet and evolve by level only. If a friend told you to buy a stone, they were describing World. World's stone path is optional and it preserves the level you already gained. The free path is cheaper and throws the level away. Charmeleon's published recipe, two Fire and two Feather, is the clearest example of how a World recipe is written. Bulbasaur's line follows the same law even when the exact leaf counts are the recipe on the species page rather than a shop listing.
Mega Venusaur's stats live on the Venusaurite page. Do not farm that item on World. For the other starter, see Charizard. For the hunt you will use at level 20, see the hunt guide.

FAQ
Does Bulbasaur evolve with a stone on net?
No. Ivysaur is level 16 and Venusaur is level 32.
What about World?
Hunt level 20 for the species. Evolution follows the target hunt level. A stone keeps your level. The free path resets the Pokémon to level 1.
Where does Venusaurite fit?
Only on Pokeidle.io as a mega stone, and on net as a level-100 mega with no item. World has no Mega Stone in the item catalog.
