Ask HN: Alternatives to TFS

We're in need of the standard tool set for our software development. The team is small (6) and very senior and has been getting by for years basically with each engineer working in isolation. The company has new goals for growth and this approach clearly will not scale. So before we try to bring additional engineers in, I need to establish a respectable process and tool set. Ideally, I'd like to introduce a unified system that covers all life-cycle activities from Requirements to Release (we're not a web server company, so dev-ops is not needed). Unified simply because I'd like to minimize the amount of inter-product integration and version management we have to suffer. We're lean. Well. Chubby, mostly, but not much time for a lot of tool set administration. Team Foundation Server appears to have the features we'd need, but we're not a Microsoft house, mostly 'C', with a sprinkling of Python and TCL. The interesting bits are: - source code management - reporting (I assume that means bugs/feature requests) - requirements management - project management (for both agile software development and waterfall teams) - automated builds - lab management - testing and release management capabilities Thanks for any suggestions, recommendations or insights you can offer.
