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.

Quickstart

Get the d1-manager source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/JacobLinCool/d1-manager.gitcd d1-manager# follow the project's README for install & configuration

Best use cases

Rapid D1 Database Admin Interface

Teams using Cloudflare D1 who need a quick, self-hosted UI for browsing schemas, running ad-hoc queries, and editing records without CLI overhead.

Non-Technical User Data Access

Enable business users or content teams to view and modify database records through a web browser without direct SQL knowledge, especially leveraging the semantic query feature.

D1 Multi-Database Management

Organizations running multiple D1 instances can bind all of them to a single manager instance and switch between databases in one UI.

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.

Security considerations

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.

d1-manager FAQ

Can I use D1 Manager without Cloudflare Pages?
Not without significant rework. The project is built on SvelteKit's Cloudflare Pages adapter and relies on D1 bindings. Porting to another host would require replacing the Pages adapter and database connectivity layer.
Is my data secure when I use the semantic query feature with OpenAI?
Your database schema and natural language queries are sent to OpenAI's API if you enable that feature. Review OpenAI's data retention and privacy policies. Alternatively, use Cloudflare AI Workers to keep queries in the Cloudflare ecosystem.
Can I use D1 Manager for production databases?
It can be used for production read-heavy or admin tasks, but lacks audit logging, transaction rollback, and fine-grained permissions. Use it alongside monitoring and backups; do not rely on it as your sole admin interface for critical systems.
What versions of D1 are supported?
Not explicitly documented. Assumed to support current D1 API. Check GitHub issues or test your D1 version before deploying to production.
