Stripe has bought OpenRouter. The deal was announced on 19 August 2026 and closed on 10 November 2026, and OpenRouter says its name, product and existing integrations stay as they are. For a writer using an OpenRouter key in SillyTavern, Novelcrafter or anything else, nothing has changed yet: the same key works, the same 5.5% fee applies to credit purchases, and no new price or data policy has been announced.
What the OpenRouter acquisition is, in dates
| Date | What happened | Source |
|---|---|---|
| May 2026 | OpenRouter raises a $113M Series B at a reported $1.3B valuation | TechCrunch, 16 Aug 2026 |
| July 2026 | The Wall Street Journal reports the two are in talks | same |
| 16 Aug 2026 | Bloomberg reports the deal is signed, at more than $7 billion | same |
| 19 Aug 2026 | Stripe announces it "has agreed to acquire OpenRouter"; OpenRouter posts "OpenRouter is joining Stripe" | Stripe newsroom, OpenRouter blog |
| 10 Nov 2026 | Stripe says the acquisition has closed | DEV Community summary, 11 Nov 2026 |
Neither company has published a price. The figures in the press differ: more than $7 billion (Bloomberg), about $7.5 billion (the New York Times), more than $8 billion in cash and stock (Axios). Treat any single number as reported, not confirmed.
Stripe was already OpenRouter's payment processor before the deal, so the card you topped up with was going through Stripe anyway.
What changed for writers on OpenRouter (and what didn't)
OpenRouter's own announcement makes three promises, in these words: "same mission, same name, same product, same roadmap"; "If you build on OpenRouter today, nothing about your integration changes"; and "Routing decisions will remain driven by one thing: what's best for you, the user."
The post says nothing about fees, nothing about the free models, nothing about logging or zero data retention. Stripe's release talks about "Token Billing" and helping businesses cut token costs. Nothing in it is aimed at someone writing a novel. Neither post mentions content rules either: nothing on adult fiction, uncensored models or what a payments company will allow through, which is the question SillyTavern users ask first. Until one of them says otherwise, the rules are the ones OpenRouter and each model's host already had.
OpenRouter's terms on 12 November 2026: the baseline to compare against
If the terms move under Stripe, this is what they moved from. Each line is from OpenRouter's own pricing page or FAQ, read on 12 November 2026.
| Term | Today |
|---|---|
| Fee on buying credits | 5.5% (8% on Business accounts) |
| Model prices | The provider's list price, passed through |
| Free models | 25+ models, 20 requests a minute, 50 a day; 1,000 a day after buying at least $10 of credits |
| Your own provider key (BYOK) | No fee on the first $25,000 a month at list price, 5% after |
| Do credits expire? | OpenRouter "reserve[s] the right to expire unused credits after one year of purchase" |
| Logging | Metadata (time, model, token counts) logged; prompts and completions not logged unless you opt in, for a 1% discount |
| Zero data retention | A privacy setting: "ZDR only" routes only to hosts that keep nothing; if none fits, the request fails |
Checked 12 November 2026: on a $10 top-up, the 5.5% fee is about 55 cents. On a $25 top-up, about $1.38. That's the number to watch for writers: the DEV Community write-up of the close names the take rate and routing neutrality as the two things a payments owner could change, and neither company has said either will.
For a novelist the other two lines matter more than the fee. The free-model cap is what decides whether a free model can carry a whole draft (it can't at 50 requests a day; the free models guide has the per-model detail). And the one-year expiry clause means credits bought for a book you pause can, under today's terms, lapse.
What people are searching about it
The search demand around the deal, from Google Keyword Planner (US, monthly, pulled 12 November 2026):
| Query | Last month | Monthly average, past year | Trend (last 3 months vs the 3 before) |
|---|---|---|---|
| openrouter acquisition | 1,600 | 590 | ×6.6 |
| openrouter stripe | 880 | 480 | ×6.0 |
| openrouter inc | 880 | 720 | ×3.5 |
| openrouter alternatives | 1,600 | 880 | ×1.6 |
| openrouter pricing | 1,300 | 1,600 | ×1.0 |
| how to delete openrouter account | 110 | 90 | ×1.2 |
Searches about the company itself rose three- to six-fold, and "alternatives" is up by half. "Pricing" and "delete account" are flat: so far people are curious, not leaving.
OpenRouter alternatives that writing apps actually accept
This table puts each one's price, from its own page, next to whether Novelcrafter's tested list (updated 19 Aug 2026) and SillyTavern's API list name it. All read 12 November 2026.
| Option | How you pay (checked Nov 2026) | Novelcrafter | SillyTavern |
|---|---|---|---|
| KudoWrite (KudoAI built in) | One free credit, then one-off packs: $3.50 for 100 credits, $7.50 for 500, $12.50 for 1,000; no subscription, no key | n/a: it's the writing app | n/a |
| DeepSeek API direct | Per token: Flash $0.15 in / $0.60 out per million off-peak, double at peak hours | Not on its tested list | Listed |
| NanoGPT | PRO $12/month (open models, 60M input tokens a week), or pay-as-you-go at list price, 5% extra to pin a provider | Tested (Chrome only) | Not named |
| Featherless | Chat plan $25/month, unlimited tokens, up to 32K context, people chatting only (no app traffic) | Native connection since Oct 2024 | Not named |
| Mancer | Not checked | Tested | Listed |
| Anthropic (Claude) direct | Per token, Anthropic's prices | Unsupported from the browser | Listed |
Where the alternatives fall short
Going direct to DeepSeek means one lab's models only, and its peak-hour price is twice the off-peak one. NanoGPT's subscription leaves out Claude, GPT, Gemini and Grok, and some uncensored models. Featherless's flat Chat plan stops at 32K of context, which is roughly 24,000 words of story plus instructions, and it's for chatting, not for a writing app's calls. Every one of them is still a key you keep in an app and a balance you top up.
Is OpenRouter shutting down?
No. OpenRouter says it keeps operating under its own name with the same product. Its post cites over 10 million developers and companies and 10+ trillion tokens a day.
Do I need a new OpenRouter API key?
No. Existing keys and integrations keep working, per OpenRouter's announcement, and neither post mentions balances; no change to how credits work has been announced. If you want a safety margin anyway, set a credit limit on the key from your OpenRouter settings so a change you miss can't cost more than that.
Does Stripe see my prompts now?
Nothing published says the data handling changed. OpenRouter's FAQ says it logs request metadata but not prompts or completions unless you opt in, and its ZDR setting limits your requests to hosts that keep nothing. The acquisition posts don't mention data at all, so check the privacy page again if a policy update email arrives.
Will OpenRouter prices go up?
No change has been announced. Model prices are the providers' own, passed through; what OpenRouter controls is the 5.5% purchase fee, the free-model caps and the BYOK allowance in the table above.
The route with no router to watch
Every option above still leaves you a key, a balance and a model to pick, and the book's memory is whatever you set up yourself. KudoWrite's built-in AI, KudoAI, also runs through OpenRouter, but from KudoWrite's server, routed only to zero-data-retention hosts that don't train on prompts, on a current DeepSeek "flash" model picked weekly for price. You never make an OpenRouter account or see its fee, and if a route changes, KudoWrite deals with it.
What you do see is the book. Each paragraph you type can be Expanded into prose from your own words, at Stick, Balanced or Novel, and the story bible of characters, places and events keeps up as you write, so the model drafting chapter twelve knows who Mara is. Credits come in one-off packs and nothing expires them, which answers the one-year clause in OpenRouter's terms. It's a browser app with an English interface; you can start a book on the free credit and see how the first chapter reads.
