Project mention: I built a token-free alternative to github-readme-stats (with mini badges & sparklines) | dev.to | 2026-07-13
github-readme-stats is a brilliant project — 65k+ stars for good reason, and if you've already got it set up and happy, there's no reason to switch. This isn't a "X is dead" post. I built mine to scratch a specific itch: zero token setup, plus mini badges and sparklines in one place. If that combination is what you're after, give it a try.

Previous Serverless Version 0.5.x
⚡ Serverless Framework – Effortlessly build apps that auto-scale, incur zero costs when idle, and require minimal maintenance using AWS Lambda and other managed cloud services.
-
Self-hosted, your infrastructure. Your keys, your network, no per-token middleman fee — you pay only for the box it runs on. LiteLLM is the broad default (Python, 100+ providers, virtual keys and budgets). If the gateway must never be your bottleneck, Bifrost (Go) and TensorZero (Rust) are built for throughput. If you already run Kubernetes, the AI plugins on Kong, Higress or Apache APISIX mean one less new service to operate.

tidb
TiDB is built for agentic workloads that grow unpredictably, with ACID guarantees and native support for transactions, analytics, and vector search. No data silos. No noisy neighbors. No infrastructure ceiling.
A similar issue was also found in Tidb:

Project mention: Show HN: BlitzGraph – Supabase for graphs, built for LLM agents | news.ycombinator.com | 2026-06-23
Hello! I would say about 50% of them were bugs, 25% were features/mechanisms I loved from the the other ones, and 25% trying to push a better way to model things, which is what I never got in none of them. Typedb would be close if entities could evolve and belong to multiple types, as well as if they focused on making it adapted for app creation, but it wasn't their priority. In surrealdb I opened several issues around enhancing the graph db part, add some topological ordering to mutations the way typedb does it and several other topics. The most recent ones are in surrealdb's repo: https://github.com/surrealdb/surrealdb/issues?q=is%3Aissue%2.... Half of them have been achieved but the other half remains. With blitzgraph I tried to take the best ideas and pracrices from each, keep the tradeoffs loww, and lean as hard as possible into being AI-agent-first

Project mention: Why Vercel is still my default for shipping frontend projects | dev.to | 2026-07-13
Now, for Railway, it's a bit different, and I use it when I need a persistent backend, like maybe a WebSocket server, a background job, or something that can't be serverless. In Scholarian, I have a long-running task where the background worker has to produce a long report using Gemini, and that process generally takes three to four minutes, so I switched the backend of my app to Railway. For Vercel, that's where it genuinely breaks down. If you need a long-running process, you're either doing something hacky with edge functions or you're reaching for a different platform. And there are a couple of good options besides Railway, and for that, Encore would be my personal recommendation.
