Sandbox Price Parity Is Real, but It Isn't the Whole Bill: What E2B, Daytona, and Modal Charge per Agent Run

E2B and Daytona charge identical per-second sandbox rates while Modal meters idle time at zero. A worked per-run and monthly cost comparison, the billing-rule and isolation fine print, and the breakeven math for running agent sandboxes on a fleet you already own.

Dragonfly Without the Database: Stop Shipping the Same Gigabytes to Every Node

A 10-node fleet pulling a 1.2 GB image downloads 12 GB per deploy; P2P distribution serves it once. We price the duplicate-byte tax across fleet sizes, unpack Dragonfly's no-database lightweight mode, and compare it with Spegel, Kraken, and a plain registry mirror.

Dokploy Moved Its Enterprise Features Behind a New License — Here's Exactly What Changed

Dokploy's January 2026 restructure kept its core Apache 2.0 but put SSO, RBAC, audit logs, and white-labeling behind a source-available license. We map exactly what moved, who it affects, and the five checks to run against any self-hosted PaaS license.

Daytona's $3.95/hr H100 vs Owning the Card: The Breakeven Math for GPU Agent Sandboxes

Daytona's $3.95/hr H100 vs Owning the Card: The Breakeven Math for GPU Agent Sandboxes

Daytona rents H100 sandbox hours for $3.95 while an RTX 5090 costs $4,700 on the street. A worked rent-vs-own comparison across three usage levels pinpoints the ~50-hour monthly breakeven — plus the Docker-default isolation catch.

Daytona Went Closed-Source: What 'Self-Hostable' Means Now That the Control Plane Is Private

Daytona Went Closed-Source: What 'Self-Hostable' Means Now That the Control Plane Is Private

Daytona moved its core to a private codebase in June 2026, freezing the public repo at v0.190.0. A before/after accounting of what self-hosting still covers, a five-question checklist for any vendor's claim, and how E2B, Modal, Beam, Microsandbox, and the Nightona fork score.

Your Controller Makes 11 API Calls, Then Goes Quiet: What the controller-runtime Cache Costs a Cluster API Fleet at Scale

Your Controller Makes 11 API Calls, Then Goes Quiet: What the controller-runtime Cache Costs a Cluster API Fleet at Scale

A controller-runtime controller's API reads cost almost nothing after startup — one snapshot plus one watch per type. The bill comes due in memory and restart bursts instead: how the Reflector/Indexer pipeline works, the three cache mistakes everyone makes, and a 50/200/500-Machine sizing table for Cluster API fleets.

Freeze the Crash: How CRIU Container Checkpoints Turn a Crash-Looping Pod Into a Debuggable Core Dump

Freeze the Crash: How CRIU Container Checkpoints Turn a Crash-Looping Pod Into a Debuggable Core Dump

One kubelet API call freezes a failing container into a tarball of memory, file descriptors, and process state. What the January 2026 Checkpoint/Restore Working Group means, the exact checkpoint-debug-restore loop, and the four boundaries — TCP sockets, GPUs, sandboxed runtimes, pod-level restore — that still say no.

Your APM Says the Deploy Was Green. The Agent Retried the Migration Three Times

Your APM Says the Deploy Was Green. The Agent Retried the Migration Three Times

An agent can return HTTP 200 with zero errors while looping, misusing tools, or producing confident nonsense. This is what an OpenTelemetry run trace of an agent-operated deploy actually looks like — and the five telemetry emissions a platform has to produce natively before its first agent-run rollout.

Cloudflare Sandboxes Are GA: Active-CPU Billing vs E2B/Daytona, Repriced Line by Line

Cloudflare Sandboxes Are GA: Active-CPU Billing vs E2B/Daytona, Repriced Line by Line

Cloudflare's GA Sandbox pricing bills CPU only while it burns and memory while the container stays awake. We run 30,000 bursty agent sessions through the rate card against E2B, Daytona, and Modal, find the break-even near 62% CPU-active, and name what the math can't change: it only runs on Cloudflare.
