Temporal

Temporal is a durable execution platform simplifying the construction of fault-tolerant applications by automatically managing failures, retries, and state persistence at each workflow step. Its unique 'durable execution' approach eliminates the need to manually code complex error recovery logic and state machines: workflows hosted in Temporal resume at the exact state where they failed on outage, without progress loss, even after weeks of execution. The platform offers native SDKs for Go, Java, Python, TypeScript, .NET, and other languages, letting developers write in natural code without learning a proprietary DSL. Temporal Cloud provides three tiers: Essentials ($100/month, 1M actions, 99.9% SLA), Business ($500/month, 2.5M actions, 2h support), Enterprise (custom, 10M+ actions, 24/7 30min support). Deployed by OpenAI, Salesforce, NVIDIA, and Uber with 99.9999% uptime over 9 years.

Temporal does not provide a French-language interface and remains exclusively English-language. The MIT-licensed open-source can be self-hosted on Kubernetes/Docker at no cost, while Temporal Cloud offers a managed version with automatic scaling and operational support. Usage-based billing ($50 per million ingress actions, decreasing to $25 at high volumes, plus active storage $0.042/GBh and history $0.00105/GBh) lets small projects start with $1,000 free credits. The learning curve exists but remains accessible to fullstack developers comfortable with distributed workflow concepts; the absence of visual UI or no-code makes it less accessible to non-technical users.
