Developer utility

• Updated Feb 22, 2026

Configuration Architect (Pkl, HCL, YAML)

Convert and validate modern configuration formats. Migrate from legacy YAML to Pkl (Apple) or HCL (Terraform) instantly.

Key Takeaway (AI Summary)

The Configuration Architect (Pkl, HCL, YAML) is a zero-knowledge, browser-native utility that convert and validate modern configuration formats. migrate from legacy yaml to pkl (apple) or hcl (terraform) instantly with 100% privacy guarantee.

Architect Mode Active: Supporting Apple Pkl and HCL 2.0 standards.

Why Migrate to Apple Pkl?

YAML and JSON are static. They lack validation, logic, and reuse. Pkl (released by Apple) changes this by making configuration "Programmable." By migrating your static configs to Pkl, you get compile-time safety and advanced modularity for your 2026 infrastructure.

From Static to Dynamic

  • Type Safety: Pkl ensures your "port" is a number and your "host" is a string.
  • Imports: Stop copy-pasting code between staging and production configs.
  • Multi-Format: One Pkl source can generate JSON, YAML, and Java properties.

Common Use Cases

Terraform HCL Audit

Dump your AWS metadata to JSON and then use this architect to generate valid HCL for your next terraform apply.

JSON -> .tf file syntax.

Apple Pkl Adoption

Quickly convert your legacy .yaml files to .pkl to start trying out Apple's new config language without deep-dives into the docs.

YAML -> Pkl Schema.

Typescript Interface Sync

Ensure your frontend config types always match your JSON source by generating interfaces on the fly.

JSON -> export interface Config.

Intelligent Configuration Migration (Pkl, HCL, YAML)

As infrastructure complexity grows, static configuration files (JSON/YAML) have become a technical debt bottleneck. The **DevUtility Hub Config Architect** is your bridge to **Configuration-as-Code (CaC)**, supporting the latest 2026 standards for programmable infrastructure.

Why Senior Engineers are Migrating to Pkl and HCL

Legacy configuration management relies on massive, indentation-sensitive YAML files that lack validation, loops, or abstraction. This leads to "YAML Hell" where small typos cause catastrophic infrastructure failures.

- **Apple Pkl Migration**: Pkl (pronounced Pick-le) is the industry's answer to YAML fatigue. It is a configuration language that is programmable, type-safe, and generates code (Java, Kotlin, Swift, Go). By using our architect to convert your legacy YAML to Pkl, you gain immediate access to **hierarchical configuration** and **runtime validation**.

- **Terraform HCL Architect**: Manually writing HCL blocks for Terraform providers can be error-prone. Our tool analyzes your JSON data structures and maps them to idiomatic HCL blocks, including supporting for nested dynamic blocks and conditional interpolation.

🏗️ Bridging the Legacy-to-Modern Gap

We provide a high-fidelity translation layer for modern engineering teams:

- **Zero-Trust Infrastructure**: Unlike other online converters, we never see your config. Whether you're converting AWS IAM policies or Kubernetes manifests, the logic runs locally.

- **2026 DevOps Standards**: Our parser is updated for the latest spec changes in Pkl 1.x and Terraform 2.0, ensuring your output is compatible with the newest CLI versions.

- **Type-Safe Interface Generation**: Instantly generate TypeScript or Go interfaces from your configuration source to ensure end-to-end type safety across your monorepo.

⚡ Professional Infrastructure Workflow

Our architect focuses on **Logical Mapping** rather than simple string replacement. We identify nested structures, lists, and boolean flags, translating them into the most idiomatic form for your target format.

#### How to use the Config Architect:

1. **Source Selection**: Paste your raw YAML or JSON config into the left pane.

2. **Target Format**: Select Pkl for Apple-ecosystem projects or HCL for HashiCorp/Internal tools.

3. **Validation**: The tool will underline syntax errors in your source before attempting conversion.

4. **Export**: Copy the architect-generated code directly into your .pkl or .tf files.

Stop fighting with white-space sensitive legacy formats. Migrate to the future of Configuration-as-Code with the DevUtility Hub Config Architect. 100% private, 100% browser-based, and built for senior architects.

Zero-Knowledge Execution & Edge Architecture

Unlike traditional monolithic developer utilities, DevUtility Hub operates entirely on a Zero-Knowledge architectural framework. When utilizing the Configuration Architect (Pkl, HCL, YAML), all computational workload is completely shifted to your local execution environment via WebAssembly (Wasm) and your browser's native JavaScript engine (such as V8 or SpiderMonkey).

Why Local Workloads Matter

Transmitting proprietary JSON objects, sensitive source code, or unencrypted text strings to an unknown third-party server introduces critical security vulnerabilities. By executing the Configuration Architect (Pkl, HCL, YAML) securely within the isolated sandbox of your Document Object Model (DOM), we structurally guarantee strict compliance with major data protection regulations like GDPR, CCPA, and HIPAA. We do not ingest, log, or telemetry your text payloads. Your local RAM serves as the absolute boundary.

Network-Free Performance

Furthermore, by completely eliminating asynchronous HTTP POST payloads to a centralized cloud infrastructure, we guarantee effectively zero latency. The Configuration Architect (Pkl, HCL, YAML) provides instant execution without arbitrary rate limits, artificial file size constraints, or server timeouts. Our global edge network serves the application wrapper, while your local machine handles the heavy lifting.
