Ask HN: Intercom , Uservoice and the likes under one roof for saas

We are SAAS Startup , To develop the tool we need the following features Support Team Chat Feedback Survey Product announcements Discussion room / forums Onboarding Is there a tool which provides frameworks for all these services . I Believe these frameworks are required for SAAS startup . Pricing is a concern thats why i am not considering intercom , uservoice and the likes .

Thanks in advance for your suggestions and a wish you all a very happy new year :
