Why DBModeler
Three promises the product is built on.
No accounts to create, no quotas to outgrow, no vendor holding your schema hostage.
Front-end only, secure by design
There is no backend. The app loads in your browser and stays there, and works offline once installed as a PWA. Provider tokens and repository secrets are encrypted at rest with a key derived from a master password you set — so private things stay private, even on your own device.
Your data lives where you choose
Keep your models on this device, or sync them through Google Drive, OneDrive or Dropbox. When you are ready, push the schema straight into your own GitHub or GitLab repository.
A managed edition for teams is on the way. Coming soon.

Smart SQL generation
Engine-aware DDL with correct dependency ordering — full CREATE for v1, precise ALTER migrations for every version after.
ALTER TABLE projects
ADD COLUMN archived_at TIMESTAMPTZ;
CREATE INDEX idx_projects_owner
ON projects(owner_id);First-class versioning
Every change is captured as a version. Compare, roll back, regenerate SQL or sync any past version to Git.
Schema validators
A curated catalog of validation libraries you can copy, download, or push to your repo through the same workflow as your migrations.
Constraints and rules
Primary keys, foreign keys, unique, check and default expressions — declared inline on the column or as table-level rules. Engine-aware syntax included.
PRIMARY KEY FOREIGN KEY UNIQUE CHECK DEFAULT NOT NULL
SQL import
Paste or upload existing DDL. The import planner previews every change before it touches your model.
Custom scripts
Attach pre- and post-migration SQL to any version. Seed data, grants, materialized views — anything your engine accepts, shipped alongside the schema.
-- post-migration
GRANT SELECT ON projects
TO readonly; Supported engines
14 engines. One workflow.
From classic relational stores to distributed SQL and cloud warehouses, DBModeler emits DDL that targets your real engine — never a lowest-common-denominator dialect.

duckdb Storage you control
You decide where your models live.
Connect a cloud provider for cross-device sync, or keep everything strictly on this device. Switch whenever you like.
This browser
Local-first storage via IndexedDB. Nothing leaves your device.
ready
Google Drive
OAuth 2.0 with PKCE. Folders you choose, files you own.
ready
OneDrive
Microsoft Graph integration that works with personal and work accounts.
ready
Dropbox
Native Dropbox API with background sync and conflict resolution.
ready
Auto-sync, three-way merge and offline base snapshots are built in.
Zero trust by default
Your master password never leaves the browser.
Sensitive material — OAuth refresh tokens, Personal Access Tokens and repository secrets — is encrypted at rest with a key derived from a master password you set.
Asked only when needed
You are prompted for the master password the first time you connect a storage provider (Google Drive, OneDrive, Dropbox) or a Git provider (GitHub, GitLab), and again to unlock those secrets when you return.
AES-GCM encryption at rest
Secrets are encrypted with AES-GCM using a key derived from your master password through PBKDF2. Plain-text tokens never touch IndexedDB.
We never see your password
There is no backend. The master password and the derived key live only inside this browser tab — nothing is uploaded, neither the password nor the encrypted material.
Git-native workflow
Push your schema where your code already lives.
Connect GitHub or GitLab with a Personal Access Token. Each new version becomes a commit, a branch, or a Pull or Merge Request — whichever fits your team.
- Per-project repository selection
- Branch-per-version or commit-to-default strategies
- Templated commit messages with version metadata
- Same publishing flow for schemas and validators

Versioning
Every change has a story.
DBModeler captures a full snapshot and a diff for every version. Roll back, branch off, regenerate SQL or sync to Git without losing the context behind each decision.

FAQ
Quick answers.
Is it really free?
Yes. Every feature, every engine and every storage provider — with no tier, no quota and no card on file.
Where is my data stored?
In your browser by default. You can opt in to Google Drive, OneDrive, Dropbox, or push directly to your own GitHub or GitLab repository. Nothing is ever sent to us.
Do I need an account?
No. The app loads and works immediately. You only authorize a provider when you want cloud sync or a Git push.
Does it work offline?
Yes. Install it as a PWA and the editor keeps working without a network. Sync resumes the moment you are back online.
Will there be a paid version?
A managed edition for teams is on the way. The browser app stays free, with no feature held back.
How do I report a bug or request a feature?
