The serverless experience, without the lock-in.
Celerity gives you clean, portable building blocks for backends; APIs, WebSockets, workflows, queues and more so you ship at serverless speed today and stay free to run anywhere tomorrow.
Build with freedom
Everything you need, end to end
- Develop locally, with confidence
Run your whole backend on your own machine, event sources and all, with feedback loops that stay fast as the system grows. The local environment uses open source software to stand in for cloud infrastructure, so what you test behaves like what you ship.
- Deploy without committing your future
You build against Celerity's building blocks, not a provider's APIs, so the same application can deploy as serverless or containerised workloads.
Bluelink takes care of the networking, permissions and glue, which make moving between targets a change of configuration rather than a rewrite.
Current cloud provider support will be limited, see the versions page for more information.- Production ready from the first line
Every building block arrives with the parts you would otherwise wire up by hand: authentication and CORS, built-in observability and telemetry, along with resilient WebSocket connections with their own client SDK.
You connect the pieces, Celerity applies the networking and cloud security best practices underneath.
