This table lists software replacements for Service as a Software Substitute (or SaaSS, for short).
Service as a Software Substitute means a network service that offers to do a job that ought in principle to be doable locally on your own computers(s). These jobs don't inherently depend on any network usage; indeed, involving the network in them at all is a gratuitous problem.
The right way to do such a job, the way that doesn't spy on you or take away your control of the job, is to do it in your own computer, with exclusively free software of course.
Thus, the free replacement for a SaaSS service is a free program that you can run locally to do basically the same job.
While solving the problem of SaaSS may seem sufficient, this doesn't solve other issues related to centralization and lack of standardization or of security. This page preferably lists software that helps people self-host their activities in the Internet while also providing some level of federation with other hosts; secondly, it lists replacements for some SaaSS variants in case there is no federated or no distributed self-hosted equivalent.

Static Source Code Analyzers
|Adlint||It can point out insecure or nonportable code fragments, and can measure various quality metrics of the source code. It (currently) can analyze source code compliant with ANSI C89 / ISO C90 and partly ISO C99.
When used in conjunction with other free software, this could serve as the beginnings of a replacement for Coverity Scan

- This is a selection of the more common free software applications, and is nothing like a comprehensive list.
- Software which is run locally by the user, without the need to have any server running.
- Software which can be installed and controlled by an organization, on the organization's servers to do the organization's jobs. For instance, if the organization would like its members, staff or contributors to work together to edit something, it could tell them to use Google Docs, but that would be SaaSS: Google would have control of the organization's computing. What it should do instead is run Etherpad or some other free tool on a machine the organization controls.
