I'm looking for a good solution for a cloud-based project management software for startups.
I really like 37 Signals "Basecamp", but cannot justify the monthly fee at this moment with all the open-source alternatives.
I need this core functionality:
Anyone have suggestions? I have used Zoho in the past, but my business partners do not like that.
Any opensource alternatives would be great :)
Teambox is open source, does exactly what you need (project management, time tracking, document uploads) and it looks much better than Collabtive. Their beta 4 looks even sleeker, faster, and with better UX, comparable to Wrike, but it's not open sourced yet.
You may find that you can justify the fee pretty quickly if nothing else does what you want :)
I currently use Redmine a bit; it's not quite as simple a basecamp but it does help for tracking more complex information.
Have you considered using Google Apps? I know it is not hype but it is probably all you need.
You can create spreadsheets the way you want to manage time tracking and tasks. You can upload any type of documents and you get live chat and online collaboration on documents.
