Ohm is a low resistance, Go web framework for building server-rendered web apps with clear defaults and ordinary Go code.

It gives you the shape of a complete web app without hiding Go:

• A framework CLI for creating apps and generating code.
• An app-owned CLI for serving, routing, migrating, seeding, and replaying.
• Routing behind a small Ohm handler layer.
• html/template views for pages, partials, layouts, components, forms, and errors.
• Go-native form validations with structured field errors.
• A blessed htmx adapter for target-aware server-rendered fragments.
• Typed config backed by deterministic .env loading.
• sqlc queries and goose migrations instead of an ORM.
• Structured slog logging with sensitive-value scrubbing and trace correlation.
• Low-pollution OpenTelemetry tracing at framework seams, with observed spans for slow or failing helper work.
• Replayable request snapshots that can become regression tests.

Ohm is for people who want the productive parts of a full-stack framework while keeping ownership of ordinary Go code.

Install

Install the latest released CLI:

go install github.com/mgomes/ohm/cmd/ohm@latest

From this checkout, install the local CLI:

go install ./cmd/ohm

Check the installed version:

ohm version

Start an app

Use SQLite for a local app that doesn't need Postgres:

ohm new journal --db sqlite --module example.com/journal
cd journal
cp .env.development.example .env.development
cp .env.test.example .env.test
just check
just server

Postgres is the default production path:

ohm new journal --db postgres --module example.com/journal

Set DATABASE_URL in .env.development and .env.test, then run the same checks.

Generate code

ohm generate handler Posts
ohm generate migration create_posts
ohm generate resource Posts title:string body:text

The app owns generated code. Keep it readable, testable, and changeable.

Operate the app

Each generated app has its own binary. The framework CLI is not required at runtime.

go run ./cmd/journal server
go run ./cmd/journal routes
go run ./cmd/journal migrate up
go run ./cmd/journal migrate status
go run ./cmd/journal db seed
go run ./cmd/journal replay ./tmp/replays/request.json
