BROMANDERLABS
Free, no-signup tools we build for the AI engineering community. Honest math, sharp UI, zero dark patterns.
Each tool ships with our reasoning open and our assumptions documented. If we say your rig runs Llama 3 at 42 tok/sec, you can see exactly why.
Local AI Scanner
Can your rig run that model?
Math-based VRAM, KV cache, and tokens/sec estimates for 140+ GPUs and 50+ open-weight LLMs — Llama 4, Gemma 4, Qwen3, DeepSeek R1 included. The honest answer to "Can I Run It?".
Prompt Cost Estimator
Stop guessing your API bill.
Per-call, daily, monthly, and yearly cost across 25+ models from Anthropic, OpenAI, Google, DeepSeek, Mistral, xAI, Cohere, and hosted Llama. Cache + batch math included.
Context Window Visualizer
See what fits in 128K.
Paste your codebase, docs, or chat history. Live token count + a fit-or-truncate verdict across 21 models from 32K all the way to Llama 4 Scout's 10M.
Inference Latency Map
Who's actually fast?
TTFT + throughput leaderboard across 27 provider+model combos — from Cerebras' 2,600 tok/s wafer-scale to OpenAI's reasoning-mode marathons. Sources cited, reasoning models flagged.
Math, not marketing
Every number on these tools traces back to a published formula or a benchmark we can defend. No hand-waving.
Your data, your machine
Calculators run client-side. We don't log your specs, your prompts, or your usage. Privacy is the default.
Always free
Labs tools stay free, forever. We make money building software for clients not from your attention.
