Yes. GoFr is open source and licensed under Apache 2.0. There is no paid tier, no commercial license, and no usage limits.

Yes. The full source is at github.com/gofr-dev/gofr under the Apache 2.0 license.

GoFr is developed in the open by the GoFr team and a community of contributors. See the team page for the current maintainers, and github.com/gofr-dev/gofr for ways to get involved.

Does GoFr support gRPC?

Yes. Built-in gRPC server with unary and stream interceptors, custom server options, panic recovery, and integrated observability. See Writing gRPC Servers and Clients.

Does GoFr support GraphQL?

Yes. GoFr supports schema-first GraphQL with queries, mutations, and an interactive playground. See GraphQL in Go with GoFr.

Does GoFr support WebSockets?

Yes — both server and client. Auto-reconnect, custom upgrader, and integrated observability. See WebSockets in Go with GoFr.

Does GoFr support Pub/Sub?

Yes. Built-in support for Apache Kafka, NATS JetStream, Google Pub/Sub, MQTT, AWS SQS, and Azure Event Hub through one unified Subscribe / Publish API.

Does GoFr include cron jobs?

Yes. Schedule recurring tasks with 5- or 6-part cron expressions. Each job execution gets an automatic OpenTelemetry span and metrics.

Which databases does GoFr support?

SQL: MySQL, PostgreSQL, Oracle, SQLite, SQL Server. NoSQL: MongoDB, Redis, Cassandra, ScyllaDB, Couchbase, DGraph, SurrealDB, ArangoDB. Search/Analytics: Elasticsearch, Solr, ClickHouse, OpenTSDB, InfluxDB. All ship with built-in observability.

Does GoFr have an ORM?

GoFr's SQL client provides connection pooling, observability, and parameter binding, not an ORM. Many GoFr users pair it with sqlc for type-safe queries; some use gorm. Both work fine inside GoFr handlers.

Can I plug in a custom database driver?

Yes. Implement the GoFr datasource interface to inject your own backend with full observability.

Does GoFr support OpenTelemetry?

Yes. OpenTelemetry tracing is built in with OTLP and Jaeger exporters, configurable sampling, trace-context propagation, and automatic span correlation across HTTP, gRPC, datasource calls, cron jobs, and Pub/Sub.

Does GoFr support Prometheus metrics?

Yes. Built-in Prometheus metrics for HTTP requests, gRPC, cron jobs, GraphQL operations, and your own custom counters/histograms/gauges. The /metrics endpoint is auto-exposed.

Can I change log levels in production without restart?

Yes. Point REMOTE_LOG_URL at an HTTP endpoint that returns the desired log level; GoFr's logger polls that URL and adjusts the in-process level on the fly (poll interval via REMOTE_LOG_FETCH_INTERVAL). The admin endpoint is one you operate — GoFr does not serve it on the service itself. See Remote Log Level Change.

How is GoFr different from net/http?

net/http is the standard library — it gives you HTTP and nothing else. GoFr is built on net/http and adds opinionated production layers: routing helpers, observability, datasource clients, gRPC, GraphQL, WebSockets, Pub/Sub, migrations, RBAC, and a resilient service-to-service HTTP client.

How does GoFr compare to Gin, Fiber, Echo, and Chi?

Gin, Fiber, Echo, and Chi are excellent minimal HTTP routers. GoFr has a wider scope — alongside HTTP it also includes observability, datasources, gRPC, GraphQL, Pub/Sub, migrations, and resilience patterns. See GoFr vs Gin / Fiber / Echo / Chi for a side-by-side; both approaches have their place.

Can I migrate from Gin / Fiber / Express / Flask / Spring Boot to GoFr?

Yes. Migration guides with concrete code translations are at /migrate.

Does GoFr work on Kubernetes?

Yes. GoFr is designed for Kubernetes deployment. Health endpoints (/.well-known/health, /.well-known/alive) are auto-exposed for liveness and readiness probes. Logs go to stdout in JSON; metrics expose at /metrics for Prometheus scraping.

Does GoFr support graceful shutdown?

Yes. app.Shutdown(ctx) closes the HTTP server, gRPC server, datasource connections, and loggers cleanly when the process receives a termination signal.

Can I run setup logic before the server starts?

Yes. Register a function with app.OnStart to seed databases, warm caches, or perform initialization synchronously before traffic begins.

How do I test GoFr applications?

GoFr provides built-in mocks for handlers, datasources (SQL, Redis, Mongo), HTTP services, and Pub/Sub. See Testing GoFr Applications in Go.
