What is the best free LLM for coding in 2026?

DeepSeek Coder V2 and Qwen 2.5 Coder via Ollama match GPT-4o on many benchmarks. For production code review, pair with a cloud fallback for edge cases.

Should indie hackers fine-tune or use RAG?

RAG first — 90% of use cases. Fine-tune only when you need consistent JSON output format at scale (1000+ daily requests) and have 500+ labeled examples.

Is vLLM worth the setup for solo founders?

Only above ~10k daily inference requests. Below that, Ollama + LiteLLM or managed APIs are simpler and cheaper when you factor in your time.

Best open-source LLM tools for indie hackers (2026)

Ollama, vLLM, LiteLLM, and more — what to self-host when you're bootstrapping AI features.

TL;DR

For most indie hackers in 2026, the optimal stack is Ollama for local dev, LiteLLM as a unified API gateway, and a hosted fallback (OpenRouter or Groq) for production. Self-hosting vLLM only makes sense above ~10k daily inference requests.

Best open-source LLM tools for indie hackers (2026)

Open-source LLM tooling matured dramatically between 2024 and 2026. Indie hackers no longer need a $500/mo OpenAI bill to ship AI features — but picking the wrong stack costs weeks of integration pain.

What is the best open-source LLM stack for indie hackers?

LLM tools compared for indie SaaS (2026)

Tool	Role	Cost	Best for
Ollama	Local inference	Free (+ GPU optional)	Dev, prototyping, privacy
LiteLLM	API gateway	Free (self-host)	Multi-provider routing
vLLM	Production inference	GPU hourly	High-throughput API
Open WebUI	Chat interface	Free	Internal tools, demos
LangChain	Orchestration	Free	RAG pipelines, agents

Ollama vs cloud APIs: when to self-host?

Ollama runs Llama 3.2, Mistral, and Qwen locally with a single CLI command. For indie hackers, it's the default dev environment — zero API keys, zero rate limits, full privacy for customer data during prototyping.

LiteLLM: the unified API layer every indie stack needs

LiteLLM exposes an OpenAI-compatible endpoint that routes to 100+ providers. Set budget limits per API key, configure fallbacks (Ollama → Groq → OpenAI), and swap models without changing client code. This is the single highest-ROI tool in the stack.

Recommended production architecture

Ollama on dev machine for iteration
LiteLLM on Coolify VPS as gateway
Groq or OpenRouter as fast fallback
pgvector + embeddings for RAG
Prompt caching for repeated system prompts
