Hangfire vs River

Hangfire runs background jobs in.NET and.NET Core applications without requiring a Windows Service or a separate process. It supports fire-and-forget, delayed and recurring jobs, as well as continuations, and stores jobs persistently. SQL Server and Redis are officially supported storage options, with other community-driven implementations also available. A built-in web dashboard shows processing activity and each job's state. Hangfire describes its processing as at-least-once, with automatic retries after unhandled exceptions or application termination. It can run across multiple machines and coordinates their work automatically. Listed integrations include ASP.NET, ASP.NET Core, console applications, Windows Services, WCF, Nancy and ServiceStack. Hangfire Core is open source under LGPLv3 and free for commercial use. The Open plan is free. Startup costs $500 a year, Business $1,500 a year, and Enterprise $4,500 a year, all billed per organization annually. Pro adds batches and batch continuations; Ace adds throttling features for concurrency and rate limits. Dashboard access is local by default, so remote access needs authorization configuration.

River is a background job queue for Go applications, using PostgreSQL or SQLite to store jobs. Its transactional enqueueing keeps a job from running until the database transaction that inserted it has completed. The core set includes isolated queues, unique jobs, prioritization, recurring cron jobs, snoozing, transactional completion, and test helpers. A web interface, pause and resume controls, automatic retries, error reporting, and telemetry integrations support operations. River UI is optional and self-hosted, with no external service dependencies. PostgreSQL is the primary database target; SQLite support is experimental. River Pro adds workflows that split complex work into individually retryable tasks, plus batching, concurrency limits, and ordered job sequences. The free Open Source plan includes the web UI but excludes workflows, concurrency limits, and support. Pro costs $125 a month and includes email support for up to 20 developers. Enterprise pricing is custom and includes email and Slack support, unlimited developers, and access to a SOC 2 report.
