The $0 Vibe Coding Stack: Free Tools That Actually Ship Real Apps
Everyone pays $20–$25/mo for Cursor, Bolt, or Lovable. I spent the last month vibe coding exclusively with free tools to see if they hold up. Four apps shipped, zero dollars spent. Here's the stack.
Last month I stared at my credit card statement and counted five different AI tool subscriptions. Cursor, Bolt, Lovable, Copilot, Claude Pro. Over $90/mo, and I wasn't even using most of them consistently.
So I ran an experiment. Cancel everything. Vibe code only with free tools for 30 days. See what actually ships.
The results surprised me. Four projects shipped — LinkSift, MiniCron, QuietTab, RSSlight. Zero dollars spent on tools. Real limitations, but also real output. Here's the stack I ended up with, who it's for, and where it breaks.
The Problem with Paid Stacks
Here's the subscription math most people don't do: Cursor Pro is $20/mo, Bolt.new Pro is $25/mo, Lovable Starter is $25/mo. That's $70/mo before you write a line of code. $840 a year. Before API overages, before you add Claude Pro, before you spring for a third-party deploy tool.
And here's the thing nobody admits: you don't need all three for most projects. Cursor and Bolt solve overlapping problems in different shells. Lovable is a specific answer to CRUD + Supabase apps. If you're a weekend hacker or a student, $70/mo is real money for tools you'll open twice a week.
If you want to see the cost damage of a single project before you start, run the build cost calculator — it factors in tools, hosting, and API spend.
Tool 1 — Trae
Trae is an AI IDE from ByteDance. VS Code fork, free, no credit card. The download is about 220MB. I had it running in four minutes, signed in with a Google account, and was shipping code the same hour.
What surprised me: it's better than Cursor at generic coding tasks. Autocomplete is fast. The chat panel understands repo context. File-level edits are tight. For writing a fresh React component, a Tailwind layout, or a quick script, it's honestly indistinguishable from paid tools.
Where it struggles: complex refactoring across 10+ files, agentic multi-step planning, and any task that benefits from Cursor's Composer mode. The agent feature exists but feels one generation behind. About 60% of my daily work now happens in Trae — single-file edits, quick fixes, boilerplate. My new daily driver for most of it.
Verdict: Trae is the free Cursor replacement for everything short of multi-file agent work. For big refactors or Composer-style tasks, I reach for Cline. See the full tools directory for side-by-side specs.
Tool 2 — Cline
Cline is an open-source VS Code extension that turns your editor into an agent. Think Cursor's Composer, but free, transparent, and pointed at whatever model you want. The install is one click from the VS Code marketplace. You paste in an API key — OpenRouter, Anthropic, OpenAI, or a local Ollama endpoint. Done.
Here's the trick: OpenRouter has free models that work surprisingly well for coding. Llama 3.3 70B Instruct (free) and Qwen 2.5 Coder 32B (free) both handle multi-file refactors, terminal commands, and planning. Slower than Claude, occasionally less polished, but they ship.
I ran Cline + Llama 3.3 70B for three weeks as my agent. It wrote a full Next.js marketing page, migrated a small Express backend to Hono, and fixed a handful of gnarly TypeScript errors. Response time averaged 2.3s per step — slower than Claude's 0.8s, but still usable.
Verdict: Use Cline for longer agentic tasks where waiting 5–10 seconds per step doesn't kill your flow. Perfect when you want to kick off a task and check back in 10 minutes.

Tool 3 — Aider
Aider is a terminal-based pair programmer. pip install aider-chat, point it at an API, and type aider in your repo. That's the whole setup.
It reads your repo, holds the files in context, and makes edits as git commits. You tell it what you want in plain English. It writes the diff, shows you, and commits with a real message. The git-awareness is the killer feature — every edit is a rollback-able commit.
The learning curve is steeper than the GUI tools. You're in a terminal, there's no inline autocomplete, and adding files to context is a manual step. I hated it for the first two hours. By the third day, I was insane for it. There's a speed thing that happens when you stop mousing around and just type commands. Pointed at Qwen 2.5 Coder via OpenRouter free tier, it handled three of my four shipped projects' core refactors.
Verdict: Aider crushes multi-file edits once you get past the terminal learning curve. The tool is free, the free OpenRouter models cost $0, total spend is $0. Skip it if you can't commit to a week of getting comfortable with CLI-first workflows.
Tool 4 — OpenRouter Free Tier
This is the piece that makes the whole stack free. OpenRouter is a unified API gateway — one key, hundreds of models. They host a bunch of open-weight models with no per-request cost, just a daily request cap.
The free models actually worth using in April 2026:
- Llama 3.3 70B Instruct (free) — best general agent model, strong at planning
- Qwen 2.5 Coder 32B (free) — top free coder, faster on code-specific tasks
- DeepSeek V3 (free) — excellent reasoning, slower but thorough
- Gemini 2.0 Flash (free) — fastest, decent at short tasks
- Llama 4 Scout (free) — 10M context, new, good for repo-scale tasks
Daily rate limits are real. You're looking at roughly 200 requests/day on free models. For hobby projects that's plenty. For a full workday of agent use, you'll cap out by 3pm.
Verdict: The magic combo is Cline + OpenRouter + Llama 3.3 70B. Install Cline, paste your OpenRouter key, select the free Llama model, and you have a multi-file agent inside VS Code for $0.
What I Shipped
Four projects over 30 days. Roughly 30 hours total of build time. Here's the rundown.
LinkSift was a Chrome extension that batches open tabs into shareable markdown. Built entirely in Trae. Four hours. About 340 lines. It's currently sitting across the Chrome and Firefox stores at 47MB total download.
MiniCron is a personal cron dashboard for my home server. Cline + Llama 3.3 70B wrote the whole backend. Eight hours. Running 24/7 on a $5 VPS. Would've taken me a full weekend by hand; the free agent stack did it across two quiet weeknights.
QuietTab hides distracting tabs by time-of-day rules. Aider + Qwen 2.5 Coder. Six hours. Published as a free Chrome extension. The multi-file edits Aider handled here would've been painful in a GUI tool.
RSSlight is a minimalist RSS reader I actually use every morning. Trae for the UI, Aider for the Next.js + SQLite backend. Twelve hours across two weekends.
Four shipped apps. 30 hours. Total stack cost: $0. The equivalent paid stack (Cursor + Bolt + Lovable) would've been $70 in month-one subscriptions. I kept the $70.
Where the Free Stack Falls Short
I'm not going to pretend the free stack is a drop-in replacement for paid tools. It's not.
It's 2–3x slower, honestly. Claude 4.5 responds in under a second. Llama 3.3 70B on free tier averages 2.3s per step. Over a full agent task that adds up — a Cline run that takes Claude three minutes takes Llama eight.
Occasional bad output you have to re-prompt. Free models sometimes hallucinate APIs or ignore part of your instruction. Maybe 1 in 10 responses. Annoying but not fatal — re-prompt and move on.
Missing quality-of-life features. Cursor has Composer, tab-completion, and @-mentions that are genuinely better. Bolt's preview-while-you-type is addictive. The free stack doesn't match those.
Rate limits bite on heavy days. 200 free requests a day sounds like a lot until you're debugging something tricky at 2pm and hit the wall.
The upgrade signal is simple. Client work with deadlines, production SaaS where reliability matters, or any time your hourly rate blows past $70/mo divided by hours saved — pay for Cursor. For most freelancers that math closes fast.
Who This Stack Is Actually For
The free stack isn't for everyone. It's for a specific person at a specific moment.
Use it if you're a student learning to ship, a weekend hacker with two to four hours a week of build time, or testing an idea where sunk cost in tooling would kill your momentum. Use it if you care about controlling your stack instead of outsourcing to SaaS.
Skip it if you're a full-time freelancer whose time cost blows past $70/mo in a week, if you're running a production SaaS with customers depending on updates, or if you have deadlines where 2–3x slower is a dealbreaker.
For my next project I'll probably hybrid it — free stack for exploration, pay for Cursor when I hit a real deadline. But for the month I tested, $0 actually shipped four apps. That's the data.
