Self-hosted developer tools
Every listing tagged self-hosted, A to Z: 8 tools across 4 categories. Listed in alphabetical order, not ranked.
Argus
Open-source (MIT), self-hosted security operations platform: AI agents triage and investigate alerts with read-only tools, while response playbooks start in shadow mode, use reversible actions and can be approved from Slack.
Aruma
Open-source (Apache-2.0) self-hosted backend for apps built on the official Firebase SDKs: one Go binary plus PostgreSQL 18 with an embedded dashboard, serving Auth, Realtime Database, Cloud Storage, Security Rules and a Firestore-compatible document database, so on supported setups you change the config file, not your app code. No Cloud Functions; Cloud Messaging, App Check and Remote Config are planned. Pre-1.0 (v0.4.0); run it with Docker Compose or a release binary.
Costura
Open-source (Apache-2.0), self-hosted AI spend attribution: imports read-only billing from OpenAI, Anthropic, Claude.ai, Codex, OpenRouter, Cursor and GitHub Copilot, attributes each dollar to a key, workspace and person, and ties totals out to each provider's report; in beta.
Death Plan Switch
Free, MIT-licensed, self-hosted dead man's switch for solo developers: it emails you weekly and, if you stop checking in, asks your next of kin and then notifies the contacts who need to take over; PHP 8.1+, no database.
Greptile
AI code reviewer that indexes your repo as a graph of files, functions and dependencies, then runs a swarm of agents over each pull request to catch bugs beyond the diff, and learns your standards from teammates' review comments. Works with GitHub, GitLab and Bitbucket; Enterprise adds self-hosting, Gitea and Perforce.
OneDeploy
Deploys open-source apps (WordPress, Gitea, Grafana, Dify and dozens more) on a dedicated server with TLS and nightly backups, billed hourly with a monthly cap.
Pando
Open-source, self-hosted platform for running internal apps, including AI-built ones: point it at a git repo or image and it builds the app, scans it for vulnerabilities, runs it on an isolated network and puts it behind your SSO. Alpha, needs Docker; AGPL-3.0.
Stackdome
Open-source, self-hostable alternative to Railway, Render and Heroku on Kubernetes: deploy from GitHub or an image, wire services on a visual canvas, managed Postgres with backups and PITR, per-branch preview environments and whole-stack rollbacks. Drive it from a coding agent skill, the canvas or a CLI; MIT licensed.
