Among the big news that the wind surf is being obtained by cognition (after that Founder went to Google), Developers interested in AI -powered coding may be looking for new alternatives.

In a little time of time, even seen today Release of Amazon’s CaroA new agent integrated development environment (IDE) made to help developers move the developers to production from prototype, using AI workflows involved in structures, planning and engineering hardness.

The Kero default model uses Claude Swant 3.7 and 4.0 as a back end. Customers can switch between them, and future support can be added to other models.

Now in the public preview, Kero Macos (Intel and Apple Silicon) is running to start free on Windows and Linux (limited to 50 interactions per user per month), starts with $ 19 for more features with additional prices.

Why should the developers check Kero?

Kero’s purpose is to eliminate the difference between “vibing coding”-from which AI is usually allowed to produce full-fired proto-typing and repetition directions for the code or completely software process and full blocks of applications.

The device is linked to AI agents with project specifications, technical architecture and automatic task management to help a complete software development life cycle within the same interface.

Kero vs. Ki Developer?

But did Amazon not already had its own AI code completion tool, Q Developer? Yes, and it’s still available.

So why launch a full new product and brand name that offers something the same functionality? Amazon sources told Venture Bat that “Kero developers have a general intended agent to work with any platform of their choice,” contrary to the Qi developer, which is more limited in support of it. Ides of the third partyVScode, Jet Brines, Lunar Eclipse and Visual Studio.

In addition, sources pointed out that KIRO’s agent was radically different from the specific development -developed development Q Developer’s code proposes on discrete pieces. He said that some developers may also prefer to use both in tandems, which is supported by it. Q Developer Pro Subscript Which starts at $ 19 per user per month.

Promptly to produce especially with running growth

Kero’s key distinction is its specific driven development model, which guides the process from theory to implementation. “Add a review system” such as a simple up prompt AI-Assisted output stimulates a series that includes:

  • User stories with the standard of acceptance In the ears (the simplest point for the syntax of requirements) format;
  • Design documents With data flu diagram, type script interface and API schemes.
  • Task lists and sub -works Test, loading states and automatic configuration by built -in, dependent.

Developers can perform these lines at a time through the built -in agent interface of the Caro, which can have access to the logs of inline defense, progress and the implementation of the historical agent. As the development moves forward, the Caru Code maintains the springs in harmony with the base, helping teams avoid the general flow between documents and implementation.

Agent hooks automatically make usual quality tasks

Cargo Agent hooks Allow developers to create automation triggers for everyday tasks such as re -creating tests, updating documents or running a security scan.

Hooks can be linked to measures such as saving files, editing components or emphasizing comments. Once you check the setup and repo, they provide a wide range of consistency in the implementation of code quality and standards.

For example, developers can explain a hook to ensure that the new reaction components can follow the ‘only responsibility principle’ or to mobilize a secret scan before the deal. This approach increases automatic quality control without slowing down individual developers.

The Open Source Foundation Code of the Visual Studio Code Maintaining Caro Microsoft is made on OSS. It provides a basic editor’s experience without proprietary services, which allows third -party like Kero to produce its IDes with full compatibility with VS code extensions and settings.

Similarly, the KIRO VS code is compatible with extensions, settings and UI conventions. It also supports:

  • Model Context Protocol (MCP) To connect the outer tolls;
  • Agentk Multi Moodle ChatUse files, URLs or documents as context.
  • Steering rolls To customize and limit the agent’s behavior in the code base;
  • Through the social log Got hub Or GoogleNo AWS account is needed.

Pricing and availability

Kero is currently free for all users during his preview period, including Amazon Que Developer and Q. Developer Pro Subscribers.

Accessing to the preview includes the limits of “free” use, which aims to allow developers to find the carao without obstacles.

After the preview period expires, consumers will have a choice Three membership levels:

PlanMonthly priceAdded agentic interactionsNote
Kero Free$ 050 every monthIncludes spears, hooks, steering and MCP support
Kero Pro$ 191,000 every monthAll features from free, nasal use quota
KIro Pro+$ 393,000 every monthDesigned for heavy users or teams

The agent interaction includes a direct application of Kiro agents – such as starting a speculation, triggering hooks or sending a chat. The subsequent processing work (such as the implementation of the multi -phase task) does not come to the quota.

On paid projects, consumers will also be able to buy additional interactions at 4 0.04, but the overseas billing has to be clearly enabled.

AISSSted Development Environmental System is rapidly crowded, with many prominent IDs and agents competing for the developer’s attention. This is how Caru Sticks is:

TollAbstractPriced.
Amazon Qi DeveloperMulti -environment AI Assistant AWS, Ides, CLI and Chat integrated. Agent workflow through terminal or IDE. Cloud ops, great for migration and automation. Free and supportive levels are available.Free; Pro AT 19/user/month

Exhibition of Kero in Action: ‘The Spirit of Crew’

To demonstrate Kero’s abilities in a real -world context, Amazon issued a full demo project named “The soul of Kero“, An open source crafting game. The project has an example of how Kero can be used in the entire development life cycle.

More than 95 % of the game’s code was made by pointing to the base. The game features unique, procedure -made items, including custom features such as loss, quirky and magic. Players provide a complex system, which can provide a complex system that highlights the strength of the caru in the management of integrated components and develops feature sets.

The repo includes:

  • Architecture documents;
  • App security review;
  • Deliberately incomplete sample branch (for specific workflow testing) with insects;
  • A roadmap with feature ideas for future partnerships.

The purpose of this project is also aimed at learning. Challenge Dot MD, Architecture Dot MD and Files like Guide Rules.

Developers can clone, run or deploy the project locally or on AWS infrastructure, and open source contributions are welcomed Got hub.

The developer’s response and early impression

Kero’s launch created active debate on the famous developer forum of Startup Excellen Hacker newsWhere Nathan Pack, Senior Developer Advocate, AWS (Username Nathnip), Generative AI’s lawyer offered technical context and answered questions.

He emphasized that Kero reflects Amazon’s internal engineering methods and is designed to help developers stronger than small ideas, to a scale from a scale to production system.

The initial community’s reaction was mixed, but the developers were made interesting, which praised the emphasis on the sunglasses, the hooks and the structure.

Some people compared it to tools such as cloud codes and cursors, which cited the characteristics of the features and better hardness in the documents. Others expressed concern over the toll monkey and switching cost, while some preferred command line interface (CLI) based tools or easy interface.

Feedback verification also came to light around the insect, platform compatibility and the desire for giant container support. These preliminary reactions reflect both curiosity and high expectations that developers now have for AI coding tools.

Kero enters a crowded field, but it seems that its structural, especially the first philosophy and the developer have been developed in collaboration with the loopwork flose.

It is not trying to change the developers or close the entire code base. Instead, it is offering another discipline method to cooperate with the AI, from planning to delivery.

Its preview now identifies open and pricing models, Kero can mostly appeal to teams and individuals to build not only faster, but more thoughtfully-with a long-term retention, explanation and quality.
