Aug 2026
v1.9
NEW

Big-document scene storage

Large boards no longer live entirely in one database row. Oversized scenes are offloaded to encrypted object storage with just a pointer kept in the record, so heavy diagrams open and save without slowing down.

  • End-to-end encrypted upload for scenes over the inline threshold
  • Save, load, realtime, versioning and export all follow the pointer transparently
  • Signed URLs with row-level-security delegation on every fetch
SECURITY

Content Security Policy now enforced

The CSP moved from report-only to enforced on letdraw.com. connect-src is pinned to known endpoints and script-src drops inline scripts. SVG imports are sanitized before they touch the canvas.

Jul 2026
v1.8
NEW

An international, English-first site

LetDraw now speaks 11 languages with per-URL SEO. The app picks your language from the browser automatically, and every page ships localized metadata and hreflang.

  • Per-language routes with a full sitemap and canonical tags
  • Language auto-detected on first visit, changeable any time
Jun 2026
v1.7
NEW

EXPLAIN plan heat-map

Paste a Postgres or MySQL EXPLAIN in JSON and get a heat-mapped plan tree on the canvas. The slowest nodes glow, so the bottleneck is obvious at a glance. Runs entirely in the browser.

IMPROVED

Smart connectors

Arrows can now route around your shapes instead of straight through them. The new obstacle-avoiding orthogonal routing keeps busy diagrams readable, and each route is cached on the element for speed.

May 2026
v1.6
NEW

REST API and MCP server

Automate LetDraw from your own tools. Personal API tokens with scoped access unlock read, write, export and AI endpoints, and the MCP server lets an AI agent drive the canvas directly.

  • Scoped developer tokens: read, write, export, ai
  • Original MCP server, no third-party dependency
NEW

D2 round-trip and code export

Turn any diagram into Mermaid or D2 source, and bring D2 back in. All export generators are original and dependency-free.

Apr 2026
v1.5
NEW

Generate from Code

Drop in real config and get a diagram. LetDraw understands Docker Compose, Kubernetes, Terraform, Helm, DOT, SQL DDL, OpenAPI, git logs and Mermaid, with its own clustered layout.

  • Auto-detects the format you paste
  • Clustered layout tuned for infrastructure and schemas
IMPROVED

Product icons for infra boxes

The "Add icon" action stamps real product icons onto your Kubernetes and Terraform boxes, so generated diagrams look the part.

Mar 2026
v1.4
NEW

Comment anywhere

Pin a comment to any point on the canvas, not just to a shape. Great for design reviews where the note is about the empty space between things.

NEW

Multi-point arrows and cardinality

Click to add bend points to arrows and lines, and add native arrowheads including UML hollow triangles and ER crow's-foot cardinality. Every generator emits them, no hand-drawn markers needed.

Feb 2026
v1.3
NEW

Bring your own AI keys

Use your own provider keys per model. Guests and free users keep keys locally; Pro, Enterprise and self-hosted can store them encrypted with AES-GCM on the server.

Jan 2026
v1.2
NEW

Enterprise identity

Single sign-on, SCIM provisioning for users and groups, domain auto-join and self-hosted licensing are all live for teams that need them.

  • SSO with automatic domain-based joining
  • SCIM sync for users and groups
IMPROVED

Flexible billing

Payments are provider-agnostic under the hood, so the operator can switch processors without customers ever having to choose.
