Chroma
the best developer experience, and honest per-unit pricing
pip install and go, with genuinely transparent pricing — the right call up to a few million vectors and the wrong one well before a hundred.
chroma is the easiest thing here to start with by a wide margin, which is why it dominates tutorials and prototypes. that matters more than it sounds: most rag projects die from friction rather than from scaling limits.
the pricing is unusually honest — storage, writes, queries and returned data each priced per unit with no minimum base fee on the entry tier. after wrestling with vendors who route you to a sales form, that clarity is worth something.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
