Show HN: Infracost (YC W21): Be proactive with your cloud costs
Hi, we are Ali, Hassan, and Alistair, co-founders of Infracost (<a href="https://www.infracost.io/">https://www.infracost.io/</a>). Infracost helps engineers see the cost of each Terraform change before launching resources. When changes are made, it posts a comment with the cloud cost impact. For example, “you’ve added 2 instances and volumes, and change an instance type from medium to large, your bill will increase by 25% next month, from $1000 to $1250 per month”.<p>We launched in February 2021 (<a href="https://news.ycombinator.com/item?id=26064588">https://news.ycombinator.com/item?id=26064588</a>), and Infracost is now being actively used by over 3,000 companies. However, there is a shift happening in the cloud cost management space. New teams, called FinOps teams (a combination of "Finance" and "DevOps"), are being formed within companies to manage cloud costs.<p>One of the first tasks assigned to these teams is to determine "who is using what" - that is, which teams, business units, products, etc. are spending the most on cloud. To accomplish this, they use tags. Tags are labels that all cloud resources should have and are key-value pairs. For example, a server could be tagged with: product=HackerNews; environment=production; team=blueTeam. So if resources are not tagged properly, then you can’t tell who is using what.<p>However, FinOps teams face challenges because their tools are reactive. These tools begin by analyzing cloud bills and providing visibility of tags from there. This means that they are looking at resources that are already running in production and costing money. A customer recently shared, “I want all resources to be properly tagged. But if they are not, I would rather a resource not be tagged at all than be tagged incorrectly.”<p>My "aha" moment! FinOps teams can define a tagging policy that can be validated in CI/CD before resources are launched. This is important because if code is shipped with the wrong tags, FinOps teams will have to fight for sprint time to fix them. Even if you shut down an untagged resource directly in the cloud, the next time Terraform runs, the resource will launch again with no tag. You need to fix the issue at its root.<p>I’d love your feedback on our solution to the tagging problem. You define your tag key-value policy in our SaaS product, and Infracost checks all Terraform resources per change. If anything fails the policy, it posts a comment with the details of which resources need tags, and what the allowed values are. Once fixed, it will let the code be shipped to production.<p>Try it out by going to <a href="https://dashboard.infracost.io/">https://dashboard.infracost.io/</a>, setting up with the GitHub app or GitLab app, and defining your tagging policy. It will then scan your repository and inform you of any missing tags and their file and line number. You can use the free trial, but if you need more time, please message me and I’ll extend it for you.<p>I would also love to hear how others ensure that the correct tag keys and values are applied to all resources, and whether this is done proactively or reactively. Additionally, I would be interested in hearing about any lessons learned in the process.<p>Cheers

Show HN: Get notified when sites update their terms of service
After reading about what happened with NightOwl yesterday [0], I thought about what it would take to be aware of things like that in the future. I created ToSNotify to automatically notify you when a website's terms change.<p>A harder problem I've been thinking through is how to know which terms to track, since it'd be a pain to add every site I have an account with. One idea I had is to automatically get terms for apps you have installed from the app store. Any other ideas/feedback are appreciated!<p>[0]: <a href="https://news.ycombinator.com/item?id=37052508">https://news.ycombinator.com/item?id=37052508</a>

Show HN: Agentflow – Run Complex LLM Workflows from Simple JSON
So, it feels like this should exist. But I couldn't find it. So I tried to build it.<p>Agentflow lets you run complex LLM workflows from a simple JSON file. This can be as little as a list of tasks. Tasks can include variables, so you can reuse workflows for different outputs by providing different variable values. They can also include custom functions, so you can go beyond text generation to do anything you want to write a function for.<p>Someone might say: "Why not just use ChatGPT?" Among other reasons, I'd say that you can't template a workflow with ChatGPT, trigger it with different variable values, easily add in custom functions, or force the use of custom functions for steps in the workflow.<p>Someone might also say: "Then why not use Auto-GPT or BabyAGI?" Among other reasons, I'd say you can't if you want consistency because these tools operate autonomously, creating and executing their own tasks. Agentflow, on the other and, lets you define a step-by-step workflow to give you more control.<p>I'd like to do more with this, including adding more custom functions, and more examples, and more ways to trigger workflows (such as in response to events). But first, I want to make sure I'm not wasting my time! For starters, if something like this already exists, please tell me.

Show HN: Easyful – A Free Gumroad Alternative
Hi HN,<p>If you’re selling templates or digital assets online, platforms like Gumroad have a ton of amazing features . . . but they’re also expensive. It’s not uncommon to be paying 10%, 20% or even 30% of your revenue just to host and deliver some digital content to customers.<p>Instead, we think most creators should own their own Stripe account and use a lightweight fulfillment layer to send customers their orders.<p>So we built Easyful, a platform built on Stripe to email your content to customers when they buy it. And it’s free!<p>We’ve been using Easyful ourselves for a few months now. Try it out and let us know what you think!

Show HN: Chat with your data using LangChain, Pinecone, and Airbyte
Hi HN,<p>A few of our team members at Airbyte (and Joe, who killed it!) recently played with building our own internal support chat bot, using Airbyte, Langchain, Pinecone and OpenAI, that would answer any questions we ask when developing a new connector on Airbyte.<p>As we prototyped it, we realized that it could be applied for many other use cases and sources of data, so... we created a tutorial that other community members can leverage [<a href="http://airbyte.com/tutorials/chat-with-your-data-using-openai-pinecone-airbyte-and-langchain">http://airbyte.com/tutorials/chat-with-your-data-using-opena...</a>] and the Github repo to run it [<a href="https://github.com/airbytehq/tutorial-connector-dev-bot">https://github.com/airbytehq/tutorial-connector-dev-bot</a>]<p>The tutorial shows:
- How to extract unstructured data from a variety of sources using Airbyte Open Source
- How to load data into a vector database (here Pinecone), preparing the data for LLM usage along the way
- How to integrate a vector database into ChatGPT to ask questions about your proprietary data<p>I hope some of it is useful, and would love your feedback!
