of $5,500 toward Spark #1
Live defaults
The stack free compute will actually use.
One winner per category. Not a roundup. The harness reads this the way CI reads the repo. Outbid someone and the next request switches.

Open
package.json of state. The default Postgres.
Schema
Open
Zod for the wire, Drizzle for the table.
UI
Open
The design system generated interfaces inherit.
Auth
Open
Sessions, API keys, the login box everyone forks.
Harness
Open
CI for agents. The suite every Spark run executes before it ships.
Hosting
Open
Where preview apps get a URL.
Vectors
Open
The index RAG actually hits.
Queue
Open
Cron, retries, the work you do not want in the request.

Checkout for the products the harness scaffolds.
Observability
Open
Where a failed eval goes to die visibly.
Search
Open
Keyword search when vectors are overkill.
Models
Open
Fallback when the Spark is busy. The OpenAI-shaped hole.
Analytics

Whether anyone used the thing you just shipped.
SEO

Titles, sitemaps, the crawl. How the generated app gets found on the web.

Keywords, screenshots, the listing. How the generated app gets installed.
