d1-manager
D1 Manager is a web UI and API for managing Cloudflare D1 serverless databases. It provides database, table, and record management through a browser interface, plus an AI assistant that translates natural language to SQL queries.

What d1-manager is
SvelteKit-based web application deployed on Cloudflare Pages that wraps D1 database operations via API routes. Includes optional semantic query layer (OpenAI or Cloudflare AI Workers) to convert natural language input to SQL, with i18n support and environment-driven configuration.

Best use cases
Implementation considerations
- Requires Cloudflare Pages deployment and D1 database bindings; not deployable to arbitrary hosting without rework.
- Semantic query features depend on third-party API keys (OpenAI or Cloudflare AI); budget and API rate limits must be considered.
- Setup involves forking the repo and configuring Cloudflare Access manually; inline documentation is present but assumes Cloudflare platform familiarity.
- Environment variables control plugin behavior; misconfiguration may silently disable semantic query or expose internal SQLite tables.
- No built-in authentication layer beyond Cloudflare Access; custom auth or SSO integration requires code changes.
When to avoid it — and what to weigh
- Complex RBAC or Multi-Tenancy Required — The project's access model relies on Cloudflare Access for protection; fine-grained role-based access control and multi-tenant isolation are not built in.
- Sensitive Data in Unvetted Environments — If using OpenAI API for semantic queries, natural language queries and potentially schema details are sent to OpenAI servers; review compliance and data residency requirements.
- Production Mission-Critical Operations Only — No versioning, audit logging, or transaction rollback visible in core features; suitable for development/staging, less suitable as the sole admin tool for critical production systems.
- Enterprise Support Expectations — This is a community-maintained open-source project with no guaranteed SLA, commercial support, or formal release schedule.

Cloudflare Access provides perimeter authentication but does not enforce row-level security or column masking. If using OpenAI API for semantic queries, ensure compliance with data residency and privacy policies; schema and query text are transmitted to third parties. SQLite internal tables are hidden by default but can be exposed via environment variable. No visible audit logging, query history, or change tracking. Review your organization's data classification before deploying with sensitive databases.
Alternatives to consider
Cloudflare D1 CLI + Direct SQL
Simpler, no external dependencies, but requires command-line proficiency and offers no visual UI for non-technical users.
PlanetScale Insights / MySQL Workbench (for MySQL D1 alternatives)
More mature UI/UX and commercial support, but locks you into specific database platforms; not D1-specific.
Self-hosted pgAdmin / Adminer
Broader database compatibility and mature feature set, but requires separate hosting; not integrated with Cloudflare ecosystem.
