Inkeep is an agent platform with an open-source core, from about $150/mo hosted. Command+K is the assembled alternative at $29/mo: templates that ship configured, your API as a hosted MCP server, and the assistant acting as the signed-in user. kapa.ai is the enterprise documentation option; Chatbase and SiteGPT cover the low end.

We build one of the tools on this list, so read it with that in mind. We have tried to earn your trust the only way that works in a list like this: every price is sourced, every trade-off is stated including ours, and where Inkeep is the better choice we say so.
Agents, tools and workflows are things you design in the builder or the SDK. That is the point of the platform, and it is also why the first working assistant is a project rather than an afternoon.
Templates ship configured. You paste a script tag, point it at your documentation, and the assistant infers its own playbook — changing it later is a dashboard edit, not a rebuild.
The open-source path is genuinely free of licence cost, and genuinely yours to run: infrastructure, upgrades, model keys, and the on-call that comes with a customer-facing surface.
Hosted on Cloudflare with the gateway, credits, approvals and OAuth handled. If self-hosting is a hard requirement, Inkeep is the better answer and we will say so.
These are recurring themes in publicly published reviews and comparisons of Inkeep, not our own testing. Every claim links to where we read it. If something here is out of date, tell us and we will correct it.
Ordered by how often they are the right answer for a product team, not by how much we like them. Pricing verified September 2026 from public sources.
$29–$99/mo, prepaid credits, 14-day trial
Product teams who want the assistant to finish the task — resend an invoice, rotate a key — as the signed-in user, with prepaid billing and no metered overage.
Younger product with a shorter reference list than the incumbents, and no self-hosted edition.
Sales-led; median contract around $25,000/year
Developer-tool companies with deep technical documentation, high answer volume and budget for an annual contract.
No self-serve signup, limited control over how guidance is delivered.
$40–$500/mo on message credits
A solo founder who needs a documentation chatbot on a marketing site this afternoon.
Reviews concentrate on billing, refunds and slow support; the agent stops replying when credits run out.
Included with the documentation platform
Teams who want their documentation platform and their docs assistant from one vendor.
You have to move your documentation there first, and it stops at answers.
$59 / $129 / $429 per month
Marketing sites that want a trained chatbot without touching the product.
Answers only; real cost moves with model usage and message volume.
From about $20/mo
Small teams wanting a low-cost documentation bot with minimal setup.
No end-user identity model, limited control in larger deployments.
$0.99 per resolved conversation, on top of seats
Support organisations with a real ticket queue, a team of agents, and volume that justifies outcome pricing.
Bills are hard to forecast, and a resolution is inferred rather than confirmed.
If you want to engineer the agent, Inkeep is the right kind of tool and open source makes it a safe bet. If you want an assistant live this week without designing one, the trade is worth making in the other direction.
Every workspace starts with a 14-day free trial — widget, knowledge base and MCP included. No credit card. Upgrade only when you need scale.
