RushDB Cloud's new pricing: Knowledge Units are retired

Since November 4, 2026, RushDB Cloud no longer bills in Knowledge Units. You pay for the two things that cost us money, gigabytes stored and AI calls to a model provider. Reads, writes, imports and re-syncs aren't metered. Every workspace already moved over, nothing in any project changed, and if you were paying, you keep what you paid for until the date you paid through.

Highlights

• Storage is the only database meter. A nightly re-sync costs nothing extra.
• Free: 1 GB (~370K records), 3 projects. Pro $49 a month, Team $199, Enterprise by contract.
• Pro and Team start with a spend cap at 2× the plan fee. At the cap, writes pause and AI actions stop; reads keep working and nothing is deleted.
• Paid plans already bought stay active until the end of the period you paid for. No new charge before that date.

Why Knowledge Units had to go

Nobody could predict them, me included. A bulk import could burn a month of KU in an afternoon. A vector search cost KU, a filtered read didn't, and you found out which was which from the bill. Worse, KU didn't follow what running your data actually costs, so someone re-syncing the same records every night paid again for data they already had. That's not fair in either direction.

What actually costs us money, IMO, is simple. Storage sits on disk and in memory every hour whether you query it or not, so it grows with you. Compute is small with the Rust engine: a query or a write is a short burst of CPU, so I don't meter it, and each plan sets a concurrency and request-rate limit instead. AI actions, Smart Search and managed embeddings, are paid per token to a provider. So the price follows storage -> AI calls -> the plan's limits, and nothing else.

The plans

Enterprise is an annual contract with dedicated or BYOC deployment, private networking and a 99.95% SLA; write to hi@rushdb.com. A rough bill is plan fee + storage over the included amount + AI overage, so Pro with 30 GB stored is $49 + $0.50 × 10 = $54. Every limit is on the pricing page, and there's a Markdown version for your agent.

Who pays more

The cheapest paid plan went from $10 to $49, and Pro from $30 to $49. The old low tiers were priced below what a production workload costs to run and support. Free got better on the parts you actually use, with three projects instead of two, a real gigabyte, and writes that aren't metered at all. If you write a lot and store little, you'll likely pay less than before. If you store a lot and rarely touch it, you pay for the storage, because that's the cost.

On every plan, reads keep working and nothing is ever deleted, idle projects included. Payments now go through Paddle, which handles VAT and sales tax and issues the invoices; prices are listed without tax.

If you're already a customer

There's nothing to do. If you were paying for an earlier plan, it stays active until the end of the period you paid for, and you won't be charged again before then. After that date you can pick Pro or Team on the Billing page, or the workspace moves to Free with everything kept. I've written to each paying customer directly.
