Self-Host Imagor: Resize Images Straight from the URL

You upload a 4 MB photo from a decent camera. Someone opens the page on a phone over patchy 4G, and you send them all 4 MB of it so their browser can scale it down to 400 pixels wide. The usual fix is to generate thumbnails at upload time.

HAProxy Rate Limiting for AI Crawlers and Runaway Agents

Rate-limit AI crawlers, runaway agents and API keys with HAProxy stick tables. A tested config with tarpits, 429s and Retry-After headers.

Apache Answer + MCP: Give AI Agents Your Team's Answers

Your coding agent is confident. It will tell you exactly how your team deploys to staging, which Postgres flags you use, and why the billing service retries three times. It will be wrong about all three, because the real answers live in your team's heads and in a

Self-Hosted Weekly: Week 39, 2026. WordPress Exploited, Portainer CE Frozen, Ubuntu Escape

WordPress shipped two security releases in five days, and attackers were probing the second fix within hours. Ubuntu has a container escape with a public exploit and no kernel patch. Portainer confirmed that its free edition stops at 2.x. Here's what mattered this week. 1. WordPress patches

Self-Host Solidtime: An Open-Source Toggl Alternative

An open-source time tracker for agencies that bill by the hour. What's free, what costs extra, and the billable-rate setting that can rewrite last month.

Self-Host Termix: SSH, RDP and SFTP in One Browser Tab

An open source Termius alternative that puts SSH, RDP, SFTP and tunnels in one browser tab. Here is the compose file that actually works, plus the sidecar everyone forgets.

Bytebase + MCP: Gate the Migrations Your AI Agent Writes

The agent writes the migration and it looks fine. Column name is sensible, the type is right, it even remembered the index. You skim it, approve it, and it ships. Then at 2pm the ALTER TABLE takes a full lock on a forty-million-row table and the app is

Self-Host Continuwuity: A Lightweight Matrix Homeserver

Matrix has a reputation problem. Ask around about self-hosting your own chat server and someone will tell you about the Postgres tuning, the worker processes, the box that quietly ate 4 GB of RAM to serve nine people. That reputation is mostly about Synapse, the reference implementation, and it

OpenClaw and Hermes: AI Agents Without Self-Hosting an LLM

You deploy OpenClaw, open it up, and it asks which model you want to use. So you go looking for the model. You spin up Ollama next to it, pull a 7B, ask your shiny new agent a question, and wait. And wait. Then you resize the VM, and it

Self-Host Neo4j: Knowledge Graph Memory for Your AI Agent

Ask your agent "what breaks if we upgrade the auth service" and watch a pure vector store handle it. It embeds the question and returns the five most similar chunks: the auth README, a paragraph about upgrades, a runbook using the same vocabulary. What you asked for was

Paperless-ngx + Tika: Index Office Docs and Emails

You scan a contract, drop it into Paperless-ngx, and thirty seconds later you can search the text inside it. It feels like magic the first time. Then you drop in the .docx version of that same contract and it lands in your archive as a file with a name

Self-Host Microcks: Mock the APIs Your AI Agent Calls

There is a failure mode that shows up over and over once you put an agent in a retry loop, and it goes like this. The loop says "check the order status, and if it fails, retry with backoff." The upstream API returns a 502 once. The agent

DevOps

Self-Host Nexus Repository to Beat Docker Hub Rate Limits

Your pipeline goes red at three in the afternoon. Nothing changed in the code. The logs say toomanyrequests: You have reached your pull rate limit, and by the time you've finished reading the error it works again, so you re-run the job and move on. Then it

Self-Host OpenRAG: A Complete RAG Stack in One Deploy

Your RAG pipeline returns garbage answers, so you go looking for the culprit. Maybe the embedding model is too small. Maybe the vector database needs different index parameters. Maybe the chunk size is wrong. Meanwhile the actual problem happened twenty minutes earlier: your PDF parser flattened a financial table into

Self-Host n8n AI: Sandboxed Code Execution and Private Search

An AI assistant that writes code for you raises an awkward follow-up question: where does that code run? For a long time the honest answer in most automation tools was "in the same process as everything else, and we hope for the best." That answer aged badly.

PowerDNS: Self-Host Authoritative DNS with an API and DNSSEC

Nobody thinks about DNS until they need to automate it. Then you open your registrar's control panel, look for an API, and find either nothing, a rate limit that makes your certificate renewals flaky, or a "premium" tier that costs more than the domain. That'

WG-Easy: Set Up a WireGuard VPN with a Web UI in 10 Minutes

There's a moment every self-hoster hits. You've got Grafana, a Postgres admin panel, maybe an internal dashboard or two, and none of them should ever face the public internet. So you start down the rabbit hole: reverse proxy, basic auth, IP allowlists, a Cloudflare tunnel,

Geta.Team Masterclass: Build AI Employees That Work Alone

Most AI tools wait. You open a tab, you type, you copy the answer somewhere useful. Nothing happens between your prompts, and the tool forgets you the moment you close it. Geta.Team takes a different position. You hire an employee, give it a mailbox and a phone number, tell

AFFiNE 0.27: New Importers, Calendar View, and a Sync Warning

If you have ever tried to move years of notes out of Notion or Obsidian, you know the feeling. Your knowledge is right there, but it is locked inside someone else's app, and getting it out cleanly feels like defusing a bomb. AFFiNE has always pitched itself as

Self-Host Centrifugo: Real-Time Updates Without Pusher

A few years ago I lost the better part of a month to a "simple" live notifications feature. Just a little bell icon that lights up when something happens. How hard could it be? I wrote a WebSocket server, then spent the next two weeks fighting reconnections, dropped

OpenHands: A Sandbox for Your Coding Agent, Not Your Laptop

Here's a question I kept dodging until it bit me: when your coding agent runs rm -rf, whose machine is it running on? For most of last year, the honest answer for me was "my laptop." I'd point Claude Code or the OpenHands agent

Self-Host NATS: Lightweight Messaging for Your Apps and AI Agents

Every distributed system I've ever built started the same way: two services talking over HTTP. Then it's five services, each one hardcoding the others' URLs, and one restarts during a deploy while three callers time out. Suddenly you're bolting retry loops and circuit

Self-Host Infisical: A Secrets Manager for Your Apps and Agents

Here's a confession: for years my idea of "secrets management" was a .env file that lived in three places, drifted out of sync in all of them, and occasionally got pasted into a Slack thread so a teammate could unblock themselves. Then someone rotates a database

Self-Host Gotenberg: A PDF Rendering API for Your Apps and Agents

Sooner or later every app needs to spit out a PDF. An invoice, a monthly report, a signed contract, a receipt an AI agent just generated. And every time, you reach for the same cursed toolbox: bundle a headless Chrome into your container, or wrestle wkhtmltopdf, or npm-install Puppeteer

Self-Hosted Weekly: Week 28, 2026. Ollama's $65M, Chatto Goes Open Source, Camel CVEs

Another week, another pile of releases, funding rounds, and CVEs to sort through. This week the money kept flowing into open-source AI, a genuinely nice self-hosted chat app dropped its source, and Apache Camel handed everyone a reason to patch on a Monday. Here are the eight stories
