I think that the list will quickly get out of hand. How about splitting each section into a separate file and leaving only the table of contents in the main readme?

The main question is will it be okay to add this service to every matching category?

Hello, Since the urls are getting more and more everyday, it'd be keep them under control and know if they are still reachable or not. https://github.com/dkhamsing/awesome_bot is the best way to do this it seems. So, I created the .travis.yml file to trigger Travis-CI to run a build and check the urls' availability.

I hope you'll accept this PR, thanks in advance.

http://uptimeroot.com Free tier: Uptime Monitoring. 50 websites/servers can be monitored every 5 minutes. Pros: So easy to use, supports e-mail, Twitter, Slack, HipChat, push, SMS, web-hook notifications and more. Limitations: Monitoring location can't be customized. Exceeding the free tier: It is needed to pay for more monitors or 1-minute monitoring intervals.

Free DB is limited to 10 MB only. Is that too restricting?

There is also $5 option with 1GB storage for MySQL and MS SQL. Or do only free tiers qualify to this list?

Hi, I'm the creator of Checkbot. I couldn't see a category it would fit under (maybe "App testing" is close) so I created a "website testing" one. Hope you find this useful and I followed the guidelines correctly.

Thanks for the great resource!

Incapsula also offers a free plan for a service in the likes of Cloudflare. Focus on the application firewall, but includes cdn and optimization stuff. https://www.incapsula.com/pricing-and-plans.html

The documentation is unclear:

As part of AWS’s Free Tier, AWS customers can get started with Amazon DynamoDB for free. DynamoDB customers get 25 GB of free storage, as well as up to 25 write capacity units and 25 read capacity units of ongoing throughput capacity (enough throughput to handle up to 200 million requests per month) and 2.5 million read requests from DynamoDB Streams for free.

I can't tell if the phrase "AWS's Free Tier" refers to the "some things free for the first year" only, or not.

Later, in the pricing example, they write:

If you haven’t used up your free tier allotment (25 write capacity units, 25 read capacity units, 2.5 million Streams read requests, 25 GB of storage), you can run this application for free on DynamoDB.

This seems to indicate an ongoing free amount. I'm (well) outside my "free tier" first year, but I'm not currently using DynamoDB for anything.

Anyone who has used DynamoDB extensively care to comment on their actual costs? I'll have something going in a few weeks, so I can comment by then.

How about including things for customer engagements, maybe full CRMs but otherwise just "Chat" tools.

For Customer Chat tools, here are the most interesting ones IMHO (analysis done 1-2 years ago):

• Drift (https://www.drift.com) - Free for 100 active contacts, 1 seat Integrates with Slack etc.
• Crisp (https://crisp.chat/en/pricing/) - 30 day history, no integrations
• Zoho SalesIQ (https://www.zoho.com/salesiq/pricing.html) - only 100 chats a month, 5K visits
• Interakt (http://interakt.co/pricing) - No scale limits, just some functional ones.

... if you like it I can post a few more that I researched. Just don't have time to do a proper pull request with the right format etc.

Well done and thanks for a great service!
