15 Truly Free AI Tools Evaluated in 2026 Across Multiple Categories

·1 views

A DEV Community evaluation identified 15 AI tools with genuinely free tiers that do not expire as of October 2026. The assessment reviewed 50 tools across seven categories, applying strict criteria including no required credit cards and usable limits. ChatGPT's free version was noted for offering unlimited text chat using GPT-5.6 Luna, while Claude's free tier excels at long-context writing and analysis. Other category leaders include Gemini for research with Google Search, Perplexity for real-time Q&A with citations, and tools like Cursor and DeepSeek for coding assistance.

Developer Details Three Practical MCP Servers for Daily Use with Claude

A developer outlines three Model Context Protocol (MCP) servers they use daily within Claude Desktop. These servers allow Claude to interact directly with a local filesystem, GitHub repositories, and a PostgreSQL database. Each server can be installed via the official `mcp-hub` CLI and configured in a JSON file, with setup taking a few minutes. The author notes that the filesystem server requires careful path configuration due to its ability to read entire drives. All listed servers are verified packages available on npm.

Common IAM Permission Mistakes and Security Best Practices

An AWS developer outlines frequent IAM permission errors and lessons learned. Using overly broad permissions, such as allowing all actions on all resources, solves immediate access issues but creates significant security risks. The recommended approach is to grant only the specific permissions required for a task, like allowing s3:PutObject only on a designated bucket. Developers should also prefer IAM roles over embedded credentials for applications and systematically debug policies by checking both actions and resource ARNs.

Ad-blocking technique reduces domain list size by 75% using hashing

An open-source DNS sinkhole project for ESP32-C3 microcontrollers has gained attention for its efficient ad-blocking method. It converts domain names from large text blocklists into compact 40-bit hashes, requiring only five bytes of storage per domain. This process shrinks a typical 2.2 MB text file to approximately 550 KB, allowing it to run on hardware with limited memory. The project's repository trended on GitHub this week, receiving coverage from tech publications. The developer verified the technique's claimed efficiency, confirming zero hash collisions in a test of over 110,000 domains.
