StackRender is a visual database schema editor that helps developers design, evolve, and deploy databases faster.
Instead of manually writing migration scripts or managing schema changes through ORMs, StackRender lets you modify your database visually using ER diagrams and automatically generates the required SQL migrations. This makes schema evolution safer, faster, and easier to review.
Supporting PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, and Oracle, StackRender streamlines the entire database development workflow—from initial schema design to ongoing migrations as your application grows.
Sqemo is an ERD tool built around one idea: physical names should be generated from your team's naming standard, not typed by hand.
You register a word list (customer → cust, number → no) and naming rules (case style, delimiter, how to handle unknown words) first. Then you model at the logical level — "Customer Number" — and the physical column comes out cust_no, the same way for everyone, every time. Overrides are allowed but explicitly flagged, so they never spread silently. Because the correct name is computable, drift is detectable: an in-app linter flags deviations, and a CLI fails CI on violations (npx sqemo-mcp lint).
Key capabilities: • Logical/physical model separation with stable links between the two • SQL DDL import/export in seven dialects: MySQL, PostgreSQL, Oracle, SQL Server, SQLite, H2, CUBRID • DBML import/export — one round trip to move from dbdiagram • Runs free in the browser with no sign-up; projects autosave locally and live in a plain .erd.json file you can commit • MCP server (sqemo-mcp) with 36 tools — AI agents read and edit your ERD while following your naming standard • Team workspaces: shared standard, propose→approve queue for new words, and a compliance view showing which ERDs drift from the standard
StackRender SqemoStackRender's answer
StackRender combines visual database design, AI-assisted schema creation, and automatic SQL migration generation in a single platform.
Unlike traditional database modeling tools that stop at documentation, StackRender treats the database schema as the source of truth. Every change made in the ER diagram is tracked and can be converted into production-ready SQL migrations, helping teams move seamlessly from design to deployment.
StackRender's answer
Most database design tools focus on modeling, while migration tools focus on deployment. StackRender bridges both worlds.
Instead of designing a schema in one tool and manually implementing changes elsewhere, developers can design visually, track schema evolution, and generate SQL migrations from the same workspace.
StackRender helps teams:
StackRender's answer
StackRender is built for software developers, startups, engineering teams, and mid-sized companies that build database-driven applications.
Typical users include:
It is especially useful for teams that frequently evolve their database schema and want a more visual and automated workflow.
StackRender's answer
StackRender was born from a common frustration experienced by many developers: database design and database implementation are often disconnected.
Designing a schema is usually easy, but maintaining migrations, tracking schema changes, and keeping databases synchronized becomes increasingly complex as projects grow. We wanted a workflow where database design could directly drive implementation.
That idea led to StackRender—a platform where developers can design databases visually, track schema evolution automatically, and generate production-ready migrations from their changes.
StackRender's answer
StackRender is built using modern web technologies with a strong focus on performance and developer experience.
Core technologies include:
The platform is designed to support scalable cloud deployments while also offering self-hosted flexibility.
StackRender's answer
StackRender is currently used by independent developers, startups, and early-stage engineering teams building database-driven applications.
As a growing product, we are focused on working closely with our users, gathering feedback, and continuously improving the platform. We do not publicly disclose customer information at this time.
