And only GitLab gives teams complete visibility across the lifecycle with a single, trusted source of data to simplify troubleshooting and drive accountability. All activity is governed by consistent controls, making security and compliance first-class citizens instead of an afterthought. Built on Open Source, GitLab leverages the community contributions of thousands of developers and millions of users to continuously deliver new DevOps innovations. More than 100,000 organizations from startups to global enterprise organizations, including Ticketmaster, Jaguar Land Rover, NASDAQ, Dish Network and Comcast trust GitLab to deliver great software at new speeds.

  • Vue Storefront
    Vue Storefront (w2021)Active • 100 employees • Warsaw, Poland
    Vue Storefront is a Frontend Platform (Head) for Headless commerce. Available as Open Source & Enterprise. By implementing Vue Storefront, you will improve your overall User Experience and lift up your revenues by at least 20%. 1. Lightning Fast We are on a mission to improve loading times for eCommerce users, especially on mobile devices. We want to make sure, that every site using Vue Storefront will load in under 2 seconds for all users across the globe. Currently, it is their weak spot: a) It takes, on average, 15.3 seconds to fully load a mobile page. b) 75% of mobile sites take longer than 10 seconds to load. c) 53% of mobile site visits are abandoned if it takes longer than 3 seconds to load. Loading times mean better User Experience and this leads to eCommerce users buying more, giving better conversion rates: a) Walmart found that for every 1-second improvement in page load time, conversions increased by 2% b) Increase of conversion % at each stage of the Customer Buying Journey at eCommerce based on 0.1s improvement based on Google Research (https://www.thinkwithgoogle.com/future-of marketing/creativity/mobile-page-speed-data/) 2. Fast Time To Value Vue Storefront is the glue for headless commerce, giving merchants the ability to connect with any eCommerce backend, any CMS, or any other 3rd party service, as we provide those APIs by default in our cloud platform. This is saving our clients thousands of development hours. Also, because of the Progressive Web App features that we provide, there is no need to build native iOS or Android apps - everything is available through the web. In combination with frontend components provided out of the box, it is possible to build a new eCommerce frontend within weeks, not months. 3. Fast content adjustments with any Headless CMS Headless CMS is the only way to embrace omnichannel sales, and we know it. That is why the Enterprise version of Vue Storefront delivers the API-first setup of integrations with the best Headless CMSes out-of-the-box. It allows business users to edit the content & publish with a no-code approach 4. Fast learning curve for developers We use the modern tech stack that is easily adaptable by the developer community, and what is better market proof than the popularity of our Open Source Project? We are currently the 5th most popular eCommerce framework globally and the 1st Frontend eCommerce Framework globally! https://docs.vuestorefront.io/v2/ https://www.vuestorefront.io/

    Infracost shifts cloud costs left and makes FinOps proactive. It sits in the engineering workflow (CI/CD), and shows the cost impact of code changes (IaC) before the code is shipped to production. This catches costly mistakes before any money has been spent. It also checks to make sure all resources are tagged with your set tagging policy, and runs checks on the code against our FinOps policy packs, ensuring best practices are followed (e.g. GP2 volumes should be GP3). This creates a cost-aware engineering culture.

This means - product analytics, session replays, feedback tools, feature flags, experimentation, and a datawarehouse (with SQL) with one click data imports from the places you use. PostHog can be deployed to the cloud, or self-hosted on existing infrastructure, removing the need to send data externally. PostHog was created as an open source project during Y Combinator's W20 cohort and had the most successful B2B software launch on HackerNews since 2012 - with a product that was just 4 weeks old. Since then, more than 40,000 companies have installed the platform, we're doing $MMs in revenue, and have a community of 120K developers - 97% driven by word of mouth. Despite the tech market, we're default alive and doing better than ever! We've been averaging ~10% monthly revenue growth, we are [default alive](http://www.paulgraham.com/aord.html), and we didn't raised a huge / now-overpriced round in 2021. While others are focused on layoffs and struggling to grow into huge valuations, we're focusing on an awesome product for end users, hiring (a handful of) exceptional team members and seeing fantastic increases in revenue as a result.

Check it out here! https://github.com/gauge-sh/tach Caelean and Evan first met as roommates in college, and in the decade since they've both worked exclusively at startups, including multiple founding engineering roles. They both ran into this problem time and time again as their startups began to scale. In the short term, Gauge is building tools to help you scale a modular monolith. Long term, Gauge is building a way to deploy a single codebase as a set of independent services, giving you the scalability of microservices with the simplicity of a monolith.

Deep Lake powers foundational model training by acting as a vector database with significant benefits, such as (1) the ability to use multi-modal datasets to fine-tune your own LLM models, (2) storing both the embeddings and the original data with automatic version control, so no embedding re-computation is needed (3) truly serverless service with no vendor lock-in. How cool is that? GitHub loves us - we're one of the fastest-growing libraries there, and we're used by little-known companies like Google, Waymo, and Intel. No big deal.

In the future, we plan to develop an entirely new packaging and bundling format for all cloud-native packages, providing a straightforward way to install and configure packages, offering simple upgrade paths, and enabling feedback, crash reports, and analytics, similar to how Android supports Play Store developers. ‎ With Glasskube, we are transforming the cloud-native ecosystem by developing a new standard that simplifies package management, similar to systems like macOS's Homebrew or npm. Our big-picture goal with Glasskube is to build enterprise-ready infrastructure software running mission-critical workloads in every one of the more than 3 million Kubernetes clusters globally.

  • Wasp
    Wasp (w2021)Active • 2 employees • Zagreb, Croatia
    Wasp is a simple configuration language for building enterprise web apps with less code and best practices. If a developer wants to build an app like Instacart, they need to know a dozen different technologies and how to make them work together - Wasp solves this problem while still letting developers use React, Node.js and their other favourite tools. We will enable enterprises to build modern apps quickly at scale, like Databricks did for data management.
