I paid for GitHub Copilot for two years. Last month I cancelled, replaced it with a fully free, mostly-local AI coding setup, and tracked my acceptance rate and latency for 3 weeks. Conclusion up front: the free stack covers ~90% of what I used Copilot for, and it's not the 90% you'd expect.
The 4 Tools (All Free, All Tested Daily)
| Tool | What it replaces | Runs where | Cost |
|---|---|---|---|
| Continue | Copilot Chat + inline edits | Your editor, any model | $0 |
| Tabby | Copilot autocomplete | Self-hosted server | $0 |
| MonkeyCode | Agentic multi-file tasks | Web | Free tier |
| Dify | Custom AI workflows/RAG over your codebase | Self-hosted | $0 |
Tabby: The Copilot Autocomplete Clone Nobody Talks About
Self-hosted code completion, one Docker command:
docker run -it --gpus all -p 8080:8080 \
-v $HOME/.tabby:/data \
tabbyml/tabby serve --model Qwen2.5-Coder-1.5B --device cuda
Then point the VS Code extension at localhost:8080. With the 1.5B model on my GPU:
- Suggestion latency: ~180ms (Copilot averaged ~300ms for me through their API)
- Acceptance rate over 3 weeks: 31% (my Copilot historical: ~34%)
A 3-point acceptance gap, at 3x lower latency, at $0. The 1.5B model is noticeably weaker on rare APIs, but for boilerplate, tests, and repetitive patterns — which is 80% of what autocomplete actually completes — it's a wash.
Continue: Chat That Doesn't Hold Your Code Hostage
Continue is an open-source VS Code/JetBrains extension that wires any model (local Ollama, free API, whatever) into chat, inline edit, and @-mention context:
# ~/.continue/config.yaml
models:
- name: Local Qwen
provider: ollama
model: qwen2.5-coder:7b
- name: Autocomplete
provider: ollama
model: qwen2.5-coder:1.5b
roles: [autocomplete]
Highlight a function, Ctrl+I, "add error handling and write tests" — runs against the local 7B model. Zero tokens sent anywhere. For my day-job codebase, that's not a nicety, it's compliance.
MonkeyCode: Where the Free Stack Gets Agentic
Autocomplete and single-file edits are solved. The gap vs paid tools is agentic, multi-file work ("add this feature across these 6 files"). MonkeyCode is the free tool I found that actually does this reasonably — it's what I reach for when a task is too big for an inline edit but too small to justify a frontier-model subscription.

Dify: The Unglamorous One
Dify isn't a coding assistant — it's an open-source LLM app builder. I use it for one thing: RAG over our internal docs + codebase, wired to the local Ollama model. "How does our auth refresh flow work?" → answers with file references. Took an afternoon to set up with Docker Compose. Replaces the "ask a senior dev" tax for new hires.
The Honest 10% Gap
What the free stack still loses at:
- Hard architectural refactors — local 7B models lose the plot over 10+ files. Paid frontier models still win here, decisively.
- Zero-setup convenience — I spent a weekend on this. Copilot is 5 minutes. Your call what a weekend is worth vs $240/year forever.
- Rare/niche framework knowledge — small local models hallucinate obscure APIs more.
The controversial take: Copilot's moat in 2026 isn't quality — it's that devs won't spend one weekend to save $240/year, every year. The free tools crossed "good enough" a year ago and most people haven't noticed.

Have you actually tried replacing Copilot with a local setup? What broke for you — or what's the excuse holding you back?
