kestrel-app 0.5.1

AI-powered job search platform. Self-hosted, open-source, privacy-first.

Kestrel

A job search system that runs on your computer.
Finds jobs. Scores them. Tracks your pipeline. Your data stays yours.

---

Install

Pick whichever feels right. They all give you the same app.

Quick install (one command)

curl -fsSL https://raw.githubusercontent.com/pleasedodisturb/kestrel/main/install.sh | bash

Detects your OS, checks for Python 3.11+, installs Kestrel, and opens it in your browser.

Or if you have Node.js:

npx kestrel-app

Or with Homebrew (macOS):

brew install pleasedodisturb/kestrel/kestrel
kestrel start

Option 1: pip install (simplest)

pip install kestrel-app
kestrel start

Opens your browser automatically. Data stored in ~/.kestrel/.

Requires Python 3.11+. Don't have Python? Install it from python.org/downloads (Mac/Windows installer, takes 2 minutes). Or use Option 2 or 3 below instead.

Option 2: Docker (isolated, nothing touches your system)

git clone https://github.com/pleasedodisturb/kestrel.git && cd kestrel
bash setup.sh

Requires OrbStack (recommended for Mac) or Docker Desktop (Mac/Windows). Both are free. Don't know what Docker is? The step-by-step guide explains everything.

Option 3: Try in your browser (zero install)

Free with a GitHub account. Your own instance in 2 minutes. Nothing installed on your computer.

Preview

Pipeline — drag applications across stages

Discovery — AI-scored job matches

Settings — connect your integrations

What it does

• Discovers jobs from multiple boards automatically (Indeed, LinkedIn, Glassdoor, Arbeitsagentur)
• Scores them against your profile with AI - stop guessing which jobs are worth applying to
• Tracks your pipeline on a Kanban board - drag applications between stages
• Prepares you for interviews - company research, mock questions, STAR story library
• Runs daily scans via GitHub Actions - wake up to a scored digest of new matches
• Works offline - Demo Mode included, zero cost to start. Add real AI when ready.

Everything runs on your machine. No account needed. No data leaves your computer (unless you connect an AI provider).

Add real AI (optional)

Kestrel works out of the box in Demo Mode — free, offline, no account needed. When you're ready for real AI-powered scoring, you have options. Think of AI providers like electricity companies: the light switch works the same no matter who supplies the power.

Option	Cost	Privacy	Speed	Best for
Demo Mode	Free	Perfect	Instant	Exploring before committing
OpenRouter	~$3-10/mo	Good	Varies	Most users — one key, 300+ models
Anthropic (Claude)	~$3-10/mo	Excellent	~200ms	Best quality + prompt caching savings
Together AI	~$1-5/mo	Good (ZDR available)	~213ms	Budget-friendly bulk scoring
Ollama	Free	Perfect	Depends on hardware	Nothing leaves your machine, ever

Quickest path: Go to Settings → click "Connect to OpenRouter" → log in → done. No API keys to copy.

How Kestrel keeps costs low

AI APIs charge per token (roughly per word). Scoring 50 jobs a day could get expensive — unless you're smart about it. Kestrel stacks several tricks that compound:

What Kestrel does	How it helps	Savings
Prompt caching	Your profile is sent once, then "remembered" by the API. Scoring 50 jobs doesn't resend your CV 50 times.	90% off input tokens
Response caching	Asked the same question twice? Kestrel serves it from local cache. Zero API calls, encrypted at rest.	100% (free)
Token-efficient tool use	When Kestrel calls AI tools, it uses a compact format that cuts output size.	70% off output tokens
Smart model selection	Not every task needs the biggest brain. Simple yes/no classification uses a smaller, cheaper model. Complex analysis uses the full thing.	60-95% on simple tasks
Batch scoring	Scoring a big backlog overnight? Batch APIs give a flat 50% discount for non-urgent work.	50% off everything

The math: Naive approach = $15-30/month. With all optimizations = $1-5/month for the same results. Deep dive on token economics →

Choosing a provider

Don't want to think about it? Use OpenRouter. It's the universal adapter — one account gives you Claude, GPT, Gemini, and open-source models. You can always switch later.

Care about privacy? Anthropic has 7-day data retention (shortest in industry). Together AI has a one-click ZDR toggle (SOC 2 Type 2 certified). Ollama keeps everything on your machine.

On a tight budget? Together AI runs open-source models (Llama 3.3, Mixtral) on their own GPUs — no middleman markup. If you're in Europe, their Frankfurt data center means lower latency too. Great for bulk scoring where you don't need Claude-level intelligence.

Want the best of everything? Kestrel can use multiple providers at once — route simple scoring to Together (cheap), complex analysis to Anthropic (quality), and never worry about which is which.

How we build

Human-first, data-driven. Every infrastructure decision — testing, CI/CD, scoring — is backed by deep research. We investigate thoroughly, then choose the sanest path: not the most sophisticated, but the most sustainable.

Our proof is in the research artifacts. Before building anything, we run parallel research agents, synthesize findings, and publish the decision rationale so anyone can understand why things work the way they do.
