Most run entirely in your browser, so nothing you paste — a token, a password, production data — is ever sent to us.
A working reverse proxy config is the easy part. Lost client addresses, buffered streaming, silent WebSocket failures and security headers that vanish on error pages are what actually cost you an afternoon.
Record your cleanup once and replay it with a click. The transformations that matter, combining a whole folder of files, query folding and why refreshes get slow, and the automatic step you should always delete.
One machine or many — everything else follows from that. The honest operational cost of Kubernetes, the middle options most comparisons skip, and the symptoms that mean you have genuinely outgrown Compose.
The 2026 edition landed on 3 August. Excessive Agency jumped from sixth to third, System Prompt Leakage was retired for the broader Hidden Context Exposure, and the ranking is now grounded in real incident data. Every category, with the tests that matter.
A VPS runs the OpenClaw gateway well and a local model badly, and the reason is memory bandwidth rather than CPU. The arithmetic that predicts tokens per second, and the three configurations worth considering.
GitFlow, GitHub Flow, trunk-based and release trains compared by what they cost, not what they promise — including the note GitFlow's own author added advising web teams to use something simpler.
Buckets have been private by default since 2023 and S3 still leaks. What exposes data now is policies written under deadline, cross-account grants with no conditions, and presigned URLs with week-long expiries.
Access to the Docker socket is functionally root on the host. Rootless mode removes that escalation path using user namespaces — with real limitations around privileged ports, client IP addresses and device access.
A threaded and an asyncio TCP connect scanner, built from sockets — plus the limits that explain why nmap exists, and why a version banner is never proof of a vulnerability. Authorised targets only.
The Options API is not deprecated, script setup is the real default, Vuex is finished and Vue 2 has had no patches since the end of 2023. A catch-up on what moved, and the reactivity trap that still catches everyone.
