The post notes that GitHub Copilot Free grants 2,000 code completions and 50 chat requests per month, which is only partly convertible, while Cursor publishes no numeric quota and FreeBuff's session-hours do not divide into tokens.", "body_md": "# Free AI coding agents with no API key: what each one actually gives you\n\n\"Free AI coding agent\" is used for two different things. Most of the tools on the published\nlists — Cline, Aider, OpenCode, Continue — are free to *install* and then\nask you for an API key, which means the model bill arrives from a provider instead of from\nthem. That is a fine arrangement and it is not free.\n\nThe tools that actually include model access with no key and no card are a much shorter list:\n**GitHub Copilot Free, Cursor on the Hobby plan, FreeBuff, and Clixad**, with Amp\nFree and the Gemini CLI free tier alongside them in reduced form. This post is what each of\nthose grants, and which of those grants can be turned into finished work. Four of six cannot,\nand one vendor no longer publishes a number at all.\n\n## Two different things called free\n\nSearch for a free AI coding agent and you get a list with Cline, Aider, OpenCode and Continue near the top. All four are genuinely free software, all four are good, and none of them answers the question that was asked. They are clients. You point them at an API key you obtained and paid for, and the model bill arrives from OpenAI or Anthropic or Google. The tool is free; the coding is not.\n\nThere is a second category, much smaller, where inference is included: the vendor is paying the model bill, or an advertiser is. Only that category can answer \"I want to use an AI coding agent and I do not want to pay for tokens.\"\n\nThe filter worth applying to any list: **after installing this, do I need to obtain\nmodel access from somebody else?** If yes, the tool is free and the work is not. Almost\nevery \"$0 forever\" listicle mixes the two categories, which is why they all look longer than\nthe real set of options.\n\n## The shortlist that includes inference\n\nThese are the tools in wide use in August 2026 that give you model access without a key of your\nown. Figures are from each vendor's own pages, linked in [Sources](#sources-title).\n\n| Tool | Who pays for the model | What the free tier grants |\n|---|---|---|\n| GitHub Copilot Free | GitHub | 2,000 code completions and 50 chat requests per month; no credit card required |\n| Cursor (Hobby) | Cursor | \"Limited\" agent requests and tab completions; no numeric quota published |\n| FreeBuff | Advertisers, via text ads between agent turns | Six one-hour sessions per day in limited mode, DeepSeek V4 Flash; a wider picker in supported regions |\n| Amp Free | Sourcegraph | A free daily allowance, reported in May 2026 as being paused or reduced for more users |\n| Gemini CLI free tier | Flash models only since March 2026; Pro moved behind a paid subscription | |\n| Clixad | Advertisers, via a rewarded offerwall in a browser tab | 5,000 credits on signup, and up to 500,000 credits a day earned on completion |\n\n## Which grants convert into work\n\nNow the part the lists skip. A grant is only useful if you can work out what it finishes, and\nthese six are denominated in five incompatible units. The obstacle is that\n[a request is not a unit of work](/blog/free-ai-coding-tier-limits/): one ordinary\nagent task is about a dozen model calls, because the agent resends the whole conversation every\nround.\n\n| Tool | Unit granted | Converts? |\n|---|---|---|\n| GitHub Copilot Free | Completions + chat requests / month | Partly — the 50 chat requests are about four agent tasks; the completions do no agent work |\n| Cursor (Hobby) | Unpublished | No — there is no number to convert |\n| FreeBuff | Session-hours per day | No — time does not divide into tokens |\n| Amp Free | A daily allowance, being reduced | No — the figure is not stable enough to price |\n| Gemini CLI free tier | Requests per day, Flash only | No — the published quota has moved during 2026 |\n| Clixad | Credits, metered on real tokens | Yes — directly, on any model |\n\nI would rather that table had more \"yes\" in it, including for reasons of self-interest: a post where the only convertible unit is the author's own looks like a rigged demonstration. It is not rigged, it is the reason this blog keeps returning to the subject. A vendor that meters tokens can tell you what your allowance buys. A vendor that grants requests, sessions or an unnamed \"limited\" amount cannot, even if it wants to.\n\n## One vendor stopped publishing its number\n\nCursor deserves singling out, because its Hobby plan used to carry a stated quota and no longer does. The current pricing page describes limited agent requests and limited tab completions without a figure, and the limit is account-specific and visible only in the dashboard after you sign up.\n\nArticles still quote \"2,000 completions and 50 requests\" for Cursor. That number is not on the\npage any more, and repeating it here to fill a table cell would be exactly the drift this site\ntests against. So the row says \"unpublished\", which is both the accurate answer and a finding in\nits own right: [a free tier is a set of defaults\nsomebody else controls](/blog/free-ai-coding-tier-privacy/), and a default nobody publishes is one that can move without anyone\nnoticing.\n\n## What the convertible ones are worth\n\nTwo of the six can be priced. Copilot Free publishes both of its numbers, so its allowance can be\nconverted into inference at list rates through our own metering engine. The assumption for a code\ncompletion is stated rather than hidden: 1,200 input tokens of surrounding code and 40 tokens\nback, the same shape [an earlier post](/blog/free-ai-coding-tier-privacy/) declared in\nits markup, read back here rather than retyped.\n\n| Grant | On the cheapest model | On a mid coding model |\n|---|---|---|\n| Copilot Free: 2,000 completions / month | 24,000 credits | 312,000 credits |\n| Copilot Free: 50 chat requests / month | about four agent tasks, on any model | |\n| Clixad: 5,000 credits on signup | 1 task | 0 tasks |\n| Clixad: 500,000 credits a day, earned | 163 tasks | 11 tasks |\n\nTwo things in that table are worth not glossing. Copilot Free's headline allowance, the\n2,000 completions, is **24,000 credits** of inference on the cheapest model in our\ncatalogue — about a quarter of a dollar at list rates. Inline completions are cheap to\nserve, which is exactly why they are the generous part of a free tier and the chat requests are\nnot.\n\nAnd Clixad's signup bonus is **one task** on the cheapest model and none on a mid\none. It exists so the first thing you meet is the tool rather than the offerwall, and it is\ndeliberately not enough to lean on. The daily figure is what the product actually runs on, and it\narrives **on completion**: most survey attempts end in a screenout that credits\nnothing, which is normal across the offerwall industry rather than a fault in our integration.\nAnyone comparing that 500,000 against Copilot's monthly grant should weigh it against the\nattempts that pay nothing, not just the ones that pay.\n\n## How to pick\n\n**If you write mostly inline, in an editor:** Copilot Free. Its generous half is\nexactly the half you would use, and completions are the cheapest thing any of these vendors\nserves.\n\n**If you want an agent and want to start this minute:** FreeBuff. No account, no\ncard, no earning step. Its ads sit between agent turns, and its launch post states that prompts\nand messages may be analyzed to personalise them —\n[the comparison post](/blog/freebuff-vs-clixad/) covers that trade in detail.\n\n**If you want frontier models on a free tier, or an allowance you can actually count:**\nClixad. Credits meter against real usage, every model is on the same funding with no locked\ntier, and an unused hour costs nothing. The price is the offerwall: a browser tab, and attempts\nthat often pay nothing.\n\n**If you already hold an API key:** Cline or Aider, and none of this applies to you.\nYour marginal cost is the token bill you were already paying, and no included-inference tier will\nbeat holding the key yourself for predictability.\n\n## FAQ\n\n### What is the best free AI coding agent that does not need an API key?\n\nThere are four in wide use that include model access rather than asking you to supply a key: GitHub Copilot Free, Cursor on the Hobby plan, FreeBuff, and Clixad. Amp Free and the Gemini CLI free tier also include inference but have both been reduced during 2026. Which is best depends on the shape of your work rather than on a ranking, because the four grant incompatible units: Copilot Free grants completions and chat requests per month, Cursor publishes no numeric quota at all, FreeBuff grants six one-hour sessions per day in limited mode, and Clixad grants credits metered against real token usage.\n\n### Are Cline, Aider and OpenCode free?\n\nThey are free to install and they are not free to run. Each is an open-source client that you point at your own API key, so the model bill arrives from OpenAI, Anthropic or Google instead of from the tool's author. That is a good arrangement if you already hold a key and want no subscription on top, and it is not an answer to the question 'how do I use an AI coding agent without paying'. Most published lists of free coding agents mix these in with tools that include inference, which is the single most common way those lists mislead.\n\n### How much work does a free AI coding tier actually finish?\n\nUsually less than the headline number suggests, and often the question cannot be answered from the published figure at all. One ordinary agent task is around a dozen model calls, because the agent resends the whole conversation each round. So Copilot Free's 50 chat requests a month is about four such tasks, and its 2,000 monthly code completions do no agent work at all: priced on our engine at an assumed 1,200 input and 40 output tokens each, a month of them is 24,000 credits of inference on the cheapest catalogued model. Cursor's Hobby plan cannot be converted at all, because it no longer publishes a number.\n\n### Is there a free AI coding agent with no credit card required?\n\nYes, several. GitHub Copilot Free states no credit card is required, FreeBuff's launch post says \"No account. No credit card. No config file.\", and Clixad asks for a GitHub sign-in and nothing else. The credit card question and the API key question are different, though: a tool can be free of a card and still expect you to bring model access. Check whether inference is included before you check whether payment details are requested.\n\n### Why do free coding tiers keep shrinking?\n\nBecause inference costs the vendor real money per user, unlike a traditional software free tier which costs almost nothing per additional account. That makes a free allowance a marketing line item rather than a product feature, and line items get cut. Three moved during 2026 alone: Google restricted the Gemini CLI free tier to Flash models in March, Amp reported pausing or reducing its free daily allowance for more users in May, and Cursor stopped publishing a Hobby quota. None of those required your agreement, because a default is not a contract term you negotiated.\n\n## Sources\n\n- GitHub,\n[Copilot plans and pricing](https://github.com/features/copilot/plans), for the Free plan's 2,000 completions and 50 chat requests per month and its statement that no credit card is required.
