Ask HN: Do you run a SAAS app?

We've built LeaseMatrix (http://lease.io/) over the last 18 months. The stack is Linux/Apache/MySQL/Rails along with Bootstrap and Javascript. The app is a web-based alternative to a spreadsheet for commercial lease analysis and comparison. We (obviously) use Bootstrap 2.3 with very little customization, as most of our development focus has been on the backend thus far because it is heavily finance focused with many complexed calculations. We use AWS and Rackspace for hosting. Other apps we use include Stripe (love it), Intercom (love it), Optimizely (love it), Google Maps API, Google Charts API, Feedjit and Wordpress (for blog only). We've played around with integrating KISSMetrics and considered Mixpanel, but our traffic volume is such that Google Analytics + Intercom + Feedjit works well enough for now.

I work on a YouTube music player for Chrome as a side-project: http://streamus.com/. It has done reasonably well for itself - 14k users and a 4.8/5 in the store.

I think my front-end is pretty standard: jQuery, jQuery UI, jQuery Transit, qTip2, Backbone, Backbone Marionette, Lo-Dash, Jasmine.

Back-end is all Microsoft-land because I was more comfortable building it in C#. NHibernate (ORM), AutoFac (Dependency Injection), AutoMapper (DTO<->Domain object mapper), NUnit (Test). Database is MSSQL. It's hosted by AppHarbor: https://appharbor.com/

I just started to work a bit more on my side project Template2pdf (http://template2pdf.com/). It is an API to enable developers to produce nice PDFs out of templates that their customers can modify on their own.

It runs on Debian with ruby/rails, java, postgresql and some system tools.

I also do some work on a SAAS to build wireless hotspot systems. I don't own anything of it, but is an interesting field once you hit scalability problems. We use all kinds of technology but the core components would be linux/freebsd, freeradius, postgresql and ruby.

I'm just finishing up work on a foreign exchange data platform:

http://fxdata.net

The client is JavaScript and SVG.

Backend is Nginx, Java, and C++.

My primary focus is running these two SAAS apps

http://rotaville.com/ - employee scheduling, rosters, rota management

http://Big.first.name/ - print awesome name badges for your event

These apps are built on a mixture of technologies including Rails, postgresql and backbone.js

About to launch Nota (http://nota.io/), a feedback/bug tracking tool for web apps. Code base is mostly front end (Backbone) but some PHP (laravel) on the backend as well as some nodeJS.

I run an online appointment scheduling software (http://www.appointmind.com/). The software stack is PHP and MySQL on Ubuntu. I do this alongside my my freelancer job.

I run a Saas app called ReportGarden(http://reportgarden.com). It is currently my primary focus.

Our stack includes Rails+Postgresql+Delayed jobs+Pusher

http://www.SupportFu.com is my primary focus.

Backbone, Ruby, MongoDB, ElasticSearch, Redis. Everything lives in EC2

I am working hard to launch www.biz-eye.com, a tool that monitors external factors(Blacklists, PR, MozRank, etc) of a website.
