I'm working on a self-hosted search service called Hister with the goal to reduce my dependence on online search engines.

Hister is basically a full text indexer which saves all the visited pages rendered by your browser. It provides a flexible web (and terminal) search interface & query language to explore previously visited content with ease or quickly fall back to traditional search engines.

Here's a little summary of the background/motivation/beginnings: https://hister.org/posts/how-i-cut-my-google-search-dependen...

Crew Chief (https://crewchief.cc) — a Vehicle diagnostic and management tool. Plug in your OBD2 codes (or just describe symptoms) and get a structured diagnosis in under 30 seconds: ranked probable causes, DIY vs. shop cost estimates, severity rating, and matched parts/repair videos.

I have too many project cars and bikes, I wanted one place to store vin numbers for searching parts, and then just kept adding useful features.

Supports 16 vehicle types (cars, trucks, motorcycles, boats, tractors, ATVs, RVs, etc.), not just cars. Also includes maintenance tracking, a browser extension that auto-fills your vehicle info on parts sites like RockAuto and AutoZone, a community-vouched trusted shops map, and a vehicle selling wizard with state-specific bill of sale generation.

Free tier gives you 1 vehicle with a full diagnostic.

I’m building Sift, a drop-in gateway that makes LLM tool use far more reliable when tools return large JSON payloads. The usual pattern is that agents paste raw tool outputs directly into the prompt, which quickly blows up context, causes truncation/compaction, and leads to incorrect answers once earlier results disappear. Sift sits between the model and its tools (MCP, APIs, CLIs), stores the full payload locally as an artifact (indexed in SQLite), and returns only a compact schema plus an artifact_id. When the model needs something from the data, it runs a tiny Python query against the stored artifact instead of reasoning over thousands of tokens of JSON. In benchmarks across 103 questions on real datasets, this approach cut input tokens by ~95% and improved answer accuracy from ~33% to ~99%. Repo: https://github.com/lourencomaciel/sift-gateway.

Right now we are "OpenRouter for Images", with video following this week.

Our north star is creating a broader developer platform for AI media generation that includes observability, with fine-tuned vision models as a judge to monitor production traffic.

We also have a model arena and showdown page that ranks models by task, so you can find the best model for e.g. photorealism: https://lumenfall.ai/leaderboard

Our stack is Rails for the dashboard and Cloudflare Workers (Typescript / Hono) for the engine.

https://i.imgur.com/mTyjQXs.png I am still building the "make money app" for some difficult users. :) Last update was calendar integration, everything besides the invoice is a sandbox, kind of like the Unix philosophy of pipes, lots of standalone apps. You are welcome to have a look at https://peterretief.org/ demo demo123 (Not accepting any new users atm, still too raw)
