About RuntimeBench Labs

Why RuntimeBench Exists

The developer web is saturated with superficial "Hello World" tutorials that never touch production constraints. When an agentic IDE loop burns \$80 in tokens overnight due to eager MCP tool schema injection, or an AI scraper crashes on AWS with an unhandled OOMKilled (Exit Code 137), standard documentation offers no answers.

RuntimeBench was built by systems and AI engineers to publish exact, reproducible terminal diagnostics, error string crash-fixes, and verified paste-and-fix utilities.

Reproducible Testbed Infrastructure

Every benchmark, config fix, and memory limit published on RuntimeBench is verified against dedicated physical and cloud testbeds:

• Local AI Workstation: Apple M3 Max (16-Core CPU, 40-Core GPU, 36GB Unified Memory) & Ubuntu 24.04 LTS rig running an NVIDIA RTX 4090 (24GB GDDR6X VRAM).
• Windows 11 & WSL2 Test Machine: Intel Core i9-14900K, 64GB DDR5, running native Windows 11 Pro alongside WSL2 (Ubuntu 22.04 LTS kernel) to catch cross-platform backslash escape bugs and spawn npx ENOENT path mismatches.
• Low-RAM Cloud Instances: AWS EC2 t3.micro (1 vCPU, 1GB RAM) and AWS Graviton t4g.nano (0.5GB RAM) instances used specifically to simulate memory starvation, swapfile thrashing, and process eviction in Playwright/Crawl4AI workers.
• Database & Webhook Harness: Supabase PostgreSQL with pgvector, Supavisor connection poolers, and Cloudflare Worker webhooks for latency and connection pool saturation testing.
• Agentic Environments: Google Antigravity IDE, Claude Desktop, Cursor, and VS Code Roo-Code running local and stdio MCP server bridges.

Our 4 Core Operating Principles

1. Zero Sponsored Benchmarks: No cloud vendor, API provider, or tool creator can pay for rankings, soft-pedaled failure reports, or altered benchmark metrics.
2. Cross-Platform Verification: Every configuration fix includes verified syntax for Windows 11 (cmd /c npx), WSL2, and macOS/Linux.
3. Paste-and-Fix First: Where others offer vague advice, we build browser-based utilities to repair configs, calculate token overhead, and generate production bash scripts instantly.
4. Radical Transparency on Failure: If a model hallucinates, an MCP server drops connection after 60 seconds, or an API call rate limits unexpectedly, we publish the unedited stack trace and prompt diff.

Corrections & Community Testing

Runtime specifications and package dependencies shift quickly. If you discover a regression in a CLI command or an updated upstream MCP server release, please submit an issue or PR to our GitHub repository:
