AppWrite
FlashAlphaAppWrite is recommended for developers building applications who require a scalable backend solution without the overhead of managing infrastructure. It is particularly suited for developers who prefer open-source platforms and those who want to avoid vendor lock-in. AppWrite's features make it a good fit for startups, hobby projects, and even educational purposes where full control over the backend is desirable.
I've use it instead of Firebase on a 15$ DigitalOcean droplet and saved around ~$150 a month. Managing my own infra does take some extra time, but definitely worth it. The APIs and SDK are also surprisingly much easier to consume than Firebase. Waiting for the cloud version.

Initially, I was using the Supabase free tier, but I was hitting the limits, and my app was becoming stale. Then I switched to Appwrite. Both are totally different; one is SQL, while the latter one is NoSQL. Although use node-appwrite package to skip the manual schema add-ons. - Source: dev.to / 6 months ago

I built FlashAlpha for this. GET https://lab.flashalpha.com/v1/vrp/{symbol} returns ATM IV, four matched RV windows (5d, 10d, 20d, 30d) using Yang-Zhang, the VRP for each, rolling z-score and percentile, put-call directional decomposition, GEX regime, and strategy suitability scores. The historical endpoint at historical.flashalpha.com/v1/vrp/{symbol}?at= returns the same shape with point-in-time z-scores for... - Source: dev.to / 3 months ago
FlashAlpha's Historical API changes that. The contract is simple: every live analytics endpoint, replayable at any minute since 2018-04-16, returned in the same response shape. One query parameter โ at โ and you get what GEX, DEX, VEX, CHEX, VRP, max pain, dealer regime, or the full stock summary looked like at that exact minute in history. - Source: dev.to / 4 months ago
