As answered by people managing Foam and PlanVortex.
PlanVortex's answer:
PlanVortex writes the posts as well as publishing them, and it can run inside another company's product. The AI planner drafts a week of posts with copy for each network and generated images, from a topic, your photos, an article or a store catalog. The REST API, webhooks and MCP server are on every plan, the free one included, and your users connect their accounts through PlanVortex's approved apps, so you skip each network's app review.
PlanVortex's answer:
We don't publish our customers' names.
PlanVortex's answer:
Pricing is per connected account, so users and posts are unlimited, and you can start on a free plan. The dashboard and the API come with the same account, so you don't pay for one tool to manage your own brands and another to build publishing into your product. Data is hosted in Spain, prices are in euros and the GDPR data processing agreement can be downloaded from the website. Support is handled by the people who build the product.
PlanVortex's answer:
Software companies and agencies that publish to social media on behalf of their own customers, either from the PlanVortex dashboard or from inside their own product through the API. Also marketing teams that look after several brands or clients at once and want each one kept in its own organization.
PlanVortex's answer:
PlanVortex was born inside a team that was already running social media for its own clients, so it was built around what breaks in practice: expired tokens, failed posts and API changes on each network. It is built and run by Talia Softworks, S.L., a software company in Spain, and the same people who write the code answer support.
PlanVortex's answer:
TypeScript and Node.js (Express) for the API and background jobs, MongoDB and Redis for data, Keycloak for authentication, Next.js and React for the dashboard and the website, Stripe for billing, Cloudflare R2 for file storage and Docker on dedicated servers in Spain. AI generation runs through OpenRouter.

I've been using foam instead of obsidian for my personal knowledge base. It works rather well. And it's completely free and ultimately just markdown. While I might wish it was djot, I don't wish hard enough to make that so myself... - Source: Hacker News / about 2 years ago
I gave up on Obsidian and just use Foam (https://foambubble.github.io/foam/) and/or vimwiki. I just can’t get into overwrought, arbitrarily designed organization schemes or proprietary apps (Foam-managed content is just plain Markdown,... - Source: Hacker News / over 2 years ago
