# Serverless & Developer Databases — buyer checklist (RFP)

Derived from ProductArena's evidence-graded user-story taxonomy for Serverless & Developer Databases: 56 judged requirements. Priorities mirror story weights (3 = must-have, 2 = should-have, 1 = nice-to-have).

## Agent workflows

- [ ] **[must-have]** My coding agent can provision a database end to end — create it, fetch the connection string, apply schema, and run queries — through the API, CLI, or MCP without touching the dashboard
- [ ] **[should-have]** An agent can run SQL and schema operations through scoped tools that distinguish read-only from destructive actions, so I can safely delegate database work
- [ ] **[should-have]** Cheaply create thousands of isolated databases — one per agent, tenant, or preview — and manage the fleet programmatically

## Agenticness

- [ ] **[must-have]** Plug MCP servers into this product so it can use their tools
- [ ] **[must-have]** Connect an agent via an official MCP server
- [ ] **[must-have]** Drive the product through a documented public API
- [ ] **[must-have]** Delegate tasks to a built-in AI assistant inside the product
- [ ] **[should-have]** Point an agent at llms.txt or agent-oriented docs
- [ ] **[should-have]** Run the product headlessly / in CI for automation
- [ ] **[should-have]** Use an official CLI
- [ ] **[should-have]** Issue scoped/least-privilege API credentials for an agent
- [ ] **[should-have]** Build against official SDKs
- [ ] **[should-have]** Subscribe to events via webhooks
- [ ] **[should-have]** Get AI-generated insights and suggestions from my data inside the product
- [ ] **[should-have]** Set up automations that run autonomously in the background
- [ ] **[should-have]** Operate the product with natural-language commands
- [ ] **[should-have]** Explore an interactive API reference with runnable examples
- [ ] **[should-have]** Download a machine-readable API spec (OpenAPI or equivalent)
- [ ] **[should-have]** Rely on versioned APIs with a documented deprecation policy
- [ ] **[nice-to-have]** Test against a sandbox environment without touching production data

## Automation depth

- [ ] **[must-have]** Define rules that trigger actions automatically on events
- [ ] **[should-have]** Perform bulk operations across many items at once
- [ ] **[should-have]** Schedule recurring jobs or workflows
- [ ] **[nice-to-have]** Version, review, and roll back my automations

## Branching workflows

- [ ] **[must-have]** Create an instant copy-on-write branch of my database — schema and data — to develop and test against production-shaped data
- [ ] **[should-have]** Create and tear down per-pull-request database branches automatically from CI or my deploy platform
- [ ] **[nice-to-have]** Reset a branch from its parent or restore it to an earlier state without rebuilding from a dump

## Connectivity pooling

- [ ] **[should-have]** Query over HTTP or WebSockets from serverless and edge functions with an official driver built for short-lived connections
- [ ] **[should-have]** Place data or replicas in regions close to my users to keep read latency low worldwide
- [ ] **[should-have]** A built-in connection pooler handles thousands of concurrent connections without me operating my own pgbouncer or proxy

## Data capabilities

- [ ] **[must-have]** I get real engine compatibility — the Postgres, MySQL, or SQLite dialect and extensions my existing code expects — not a lookalike subset
- [ ] **[should-have]** Store embeddings and run vector similarity search natively without adding a separate vector database
- [ ] **[should-have]** Run heavy analytical aggregations over large tables fast enough for dashboards without exporting to a separate warehouse

## Local dev

- [ ] **[must-have]** Run the same engine locally and keylessly — no account or cloud dependency — for offline development and CI tests
- [ ] **[should-have]** The official CLI covers my daily loop — create, connect, shell into, and inspect databases — without opening the dashboard

## Migrations schema

- [ ] **[must-have]** Ship schema changes safely — online DDL, deploy requests, or branch-and-merge workflows — without locking or breaking production
- [ ] **[should-have]** The database works out of the box with my ORM and framework (Prisma, Drizzle, Django, Rails) with documented guides
- [ ] **[nice-to-have]** Import an existing production database with minimal downtime using a documented migration path

## Openness

- [ ] **[must-have]** Export all of my data in open formats and leave
- [ ] **[must-have]** Self-host the core product
- [ ] **[should-have]** Do everything through the API that I can do in the UI
- [ ] **[should-have]** Read the product's source under an open license

## Operations insights

- [ ] **[should-have]** See slow queries, index recommendations, and performance metrics in a built-in insights view
- [ ] **[nice-to-have]** Set spend caps or usage alerts so a runaway query or traffic spike cannot produce a surprise bill

## Pricing plans

- [ ] **[must-have]** Published per-unit pricing for compute, storage, and traffic lets me predict my bill before committing
- [ ] **[should-have]** A genuinely usable free tier lets me run real prototypes before paying

## Privacy posture

- [ ] **[must-have]** Prevent my data from being used to train AI models
- [ ] **[should-have]** Choose where my data is stored (region/residency)
- [ ] **[should-have]** Control data retention and deletion
- [ ] **[should-have]** Opt out of telemetry and usage tracking

## Reliability recovery

- [ ] **[must-have]** Restore or branch the database to any point in time within the retention window to recover from bad writes
- [ ] **[should-have]** Add read replicas and rely on documented high-availability and failover behavior
- [ ] **[should-have]** Automatic backups run on a schedule I can see and configure, and restores are self-serve

## Serverless scale

- [ ] **[must-have]** Idle databases scale to zero so prototypes and side projects cost nothing while the data stays durable
- [ ] **[must-have]** Create a ready-to-connect database in seconds through the CLI or API without capacity planning
- [ ] **[should-have]** Compute autoscales up and down with load automatically, without manual resizes or downtime
