24 alternatives to Kreya

Hi HN! For over a year we've been working on Kreya. At first, it only supported gRPC, because the alternative tools (eg. BloomRPC) were very limited in their functionality. Since then, we have added many features, trying hard to keep the UI clean while still supporting advanced use cases. Yesterday, we released Kreya v1.8, which added support for REST! In our opinion, Kreya is a good alternative to the existing tools out there. Sure, it may not support all the features that Postman has. But we think that Kreya has some innovative approaches (eg. authentication or API importers) that users…

Kreya is a development tool for testing and interacting with APIs, supporting both gRPC and REST protocols. It is designed for developers who need an alternative to Postman with a clean interface that handles advanced… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Quick list of features: - Workspaces - Tabs - Nested Folders - Lots of context menus - Response history - Plugins - Runs fully in the browser and runs offline if necessary - Chrome and Firefox extension to bypass CORS restrictions - Desktop builds for all platforms - GraphQL support - Import collections exported from Postman and Insomnia - Simple user friendly interface I built this because I love Insomnia but wanted a portable version that I could run in the…

    Hey everyone, Just wanted to share a quick update we just launched at Kodus. For those who don’t know it yet, Kodus is a code review agent that runs directly in your team’s Git workflow (GitHub, GitLab, Bitbucket… and now Azure DevOps as well). It helps maintain code quality and consistency by analyzing each PR based on your team’s own rules and repository standards. Support for Azure had been a common request — so if your team uses it, you can now plug Kodus right into your workflow and give it a try. Docs: https://docs.kodus.io/how_to_use/en/overview Repo:…

    Hi HN, I want to share with you an IntelliJ plugin I have developed and launched. Based on my own needs, I wanted a plugin that monitors my coding practices and gives me stats about them in order for me to improve on them. So, here is Kasama: An IDE plugin that works like a sport fitness tracker, gathering data on: - your coding sessions, i.e. how long are you active in the IDE and for which project - your activity in different modules, and how the activity is split between test code and prod code - your version control (git) interactions: how often you commit, the lifespan your branches,…

    Hi HN! I'm Greg and I've been working on Yaak for just over a year. I usually describe it as a Postman alternative since most developers are familiar with that, but it's targeted more toward users that just want an API client (no mocking, testing, spec design, etc). Having also created Insomnia for a similar purpose, I never thought I'd build another API client again. But, after selling Insomnia in 2019 and watching it expand into the broader feature set of Postman, I was left wanting a simpler tool again. Yaak was my answer to that. It's hard to describe how it's better than the 100 other…

    In this release I have concentrated on user experience: - Full support of shortcuts - Reworked collections management - Notifications - Improved UX gRPC clients I’ve worked with had drawbacks and didn’t fit my use-case in a way I was expecting, since I’ve started working with gRPC 3+ years ago. Since then, I wanted a tool that fits any need in gRPC world. This is why I created ezy. Compared to Insomnia and Postman, ezy offers better streams support, allows you to use Server-Side and Mutual TLS with custom TLS certificates, works with gRPC-Web and has a more slick UI/UX.

    Kapeta is an end-to-end software development platform - which will allow you to design your system using a visual "living" systems diagram that'll generate boilerplate code as you design your system. Once you're happy with the architecture - you dive into the code and fill in the blanks - where the real value is. Once you're done with your system - simply publish and deploy it to take it online. Kapeta does all the heavy lifting of creating a Kubernetes cluster (Powered by GCP atm) and adding your software to it. This is just the beginning - and we're eager to add more features and providers…

    Hey folks. I'm the author of kr8s. I’ve been working on kr8s for a while now and one of my core goals is to build a Python library for Kubernetes that is the most simple, readable and produces the most maintainable code. It should enable folks to write clean code when working with the Kubernetes API. If you're interested in how it compares with other libraries then check out [this post](https://jacobtomlinson.dev/posts/2023/comparison-of-kr8s-vs-...). Happy to answer any questions you might have in the comments here .

    hey guys. the other day i was migrating hosting providers and i just needed something not too heavy and convenient to spin up my backups for awhile and realised there is almost nothing out there. kimchi hasn't been updated for years and cockpit is heavy. so here's something i came up with in a couple hours because of a sudden urge, nothing fancy just basic creation with cloud init, lifecycle management and image/storage, but it's modern-ish and it compiles to a 8.4mb binary inclusive of the embedded web UI, CLI and API, and only dep is libvirt.

    This has been my pet project and playground for a long time and has gone throught several framework changes, overhauls, etc.. Sometime last winter I realized that there has been a lot of progress since I started using plain javascript and lit-html and that it is time for a release. And then the hard work began... But anyone who has used the browser's own developer tools for working with IndexedDB databases will probably agree that there must be more convenient methods. And even though Kahuna can't do everything I want it to yet, it's certainly a good start. Since yesterday, the webextension…

    Hi folks, Quickwit cofounder here. We started Quickwit 3 years ago with a POC, "Searching the web for under $1000/month" (see HN discussions [0]), with the goal of making a robust OSS alternative to Elasticsearch / Splunk / Datadog. We have reached a significant milestone with our latest release (0.7) [1], as we have witnessed users of the nightly version of Quickwit deploy clusters with hundreds of nodes, ingest hundreds of terabytes of data daily, and enjoy considerable cost savings. To give you a concrete example, one company is ingesting hundreds of terabytes of logs daily…

    I've built this to make it easy to host your own infra for lightweight VMs at large scale. Intended for exec of AI-generated code, for CICD runners, or for off-chain AI DApps. Mainly to avoid Docker-in-Docker dangers and mess. Super easy to use with CLI / Python SDK, friendly to AI engs who usually don't like to mess with VM orchestration and networking too much. Defense-in-depth philosophy. Would love to get feedback (and contributors: clear & exciting roadmap!), thx
