开发人员免费

Developers and Open Source authors now have many services offering free tiers, but finding them all takes time to make informed decisions. 现在,开发人员和开源软件作者有许多提供免费层级的服务,但要找到所有这些服务,需要花时间做出明智的决定。

This is a list of software (SaaS, PaaS, IaaS, etc.) and other offerings with free developer tiers. 这是一个软件列表(SaaS,PaaS,IaaS 等)和其他提供免费开发者级别的产品。

The scope of this particular list is limited to things that infrastructure developers (System Administrator, DevOps Practitioners, etc.) are likely to find useful. We love all the free services out there, but it would be good to keep it on topic. It's a grey line sometimes, so this is opinionated; please don't feel offended if I don't accept your contribution. 本列表的范围仅限于基础架构开发人员(系统管理员、DevOps 实践者等)可能会发现有用的东西。我们喜欢所有的免费服务,但最好能保持主题明确。有时这是一条灰色的线,所以这是有主见的;如果我不接受您的贡献,请不要感到被冒犯。

This list results from Pull Requests, reviews, ideas, and work done by 1100+ people. You can also help by sending Pull Requestsopen in new window to add more services or remove ones whose offerings have changed or been retired. 该列表来自 1100 多人的拉动请求、评论、想法和工作。您也可以通过发送 Pull Request 来添加更多服务,或删除那些服务内容已更改或已退役的服务。

Track Awesome List

NOTE: This list is only for as-a-Service offerings, not for self-hosted software. To be eligible, a service must offer a free tier, not just a free trial. The free tier must be for at least a year if it is time-bucketed. We also consider the free tier from a security perspective, so SSO is fine, but I will not accept services that restrict TLS to paid-only tiers. 注意:此列表仅适用于作为服务提供的服务,而不是自托软件。 为了符合条件,服务必须提供免费级别,而不仅仅是免费试用。 免费级别必须持续至少一年,如果时间有限。
