The git push heroku main workflow Heroku made famous still exists in 2026 — on Heroku itself, on self-hosted open-source clones (Dokku, Coolify, CapRover) running on a VPS you rent, and in git-integrated flows on Render, Vercel and Netlify. For a human, pick by taste and price. For an autonomous agent, the question changes: push-to-deploy always implies a remote, every managed remote lives inside an account, and almost every account sits behind a human signup — usually a credit card (Heroku's own docs: app creation and code deploys require a card-verified account). The self-hosted route removes the platform account and replaces it with a server to rent, configure and patch — different labor, not no labor. Slipdock is the one managed option where the repo itself is minted and claimed through an API: one unauthenticated POST, a free private repo, push, live URL — and purchases fenced so the agent can never move money.
| Path | What a human must do before the first push | Agent-usable? | Cost shape |
|---|---|---|---|
| Heroku (the classic remote) | Sign up, verify account with a credit card (their Dev Center: required to create apps, deploy code, use dynos, add domains); create the app | Only with a human's verified, card-backed account + token | No free tier listed; Eco $5/mo, always-on Basic $7/mo (2026-10-07 pricing page) |
| Render / Vercel / Netlify (git-connected) | Create account, link a Git provider, pick the repo; card typically required beyond free hobby limits | Same — human-owned account, agent is a guest in it | Free hobby tiers with limits; usage/pay-as-you-go beyond |
| Railway | Account signup (email/OAuth); deploys via GitHub, CLI, image or template | Token works, but the account and card are a human's; usage is uncapped by default | Per-second usage + plan fee ($5/$20); stopped services cost nothing |
| Dokku / Coolify / CapRover (self-hosted) | Rent and administer a VPS, install/harden/maintain the platform — forever | An agent can drive it, but the server is permanent unpaid labor with root access | VPS price + your ops time; no platform fee |
| GitHub Pages (+ Actions) | GitHub account; static sites only | Static-only, human-owned account | Free for public/static use within limits |
| Slipdock | Nothing before the first push: token via one unauthenticated POST; the free plan's private repo is claimed via the API. The human appears once later, by email, only to approve money | Designed for exactly this | Free: 1 app + 1 static site + repo (throttled, never invoiced); $7/$19 flat plans |
"Static site hosting API" seekers: the same table applies — on the managed platforms the API is a human account's API; Slipdock's static-site path is provisioned by the token itself.
Every command below was run for real and published with captured output in our verified tutorial — including the honest place it stopped (a free-plan slot cap returning upgrade_plan, which is a money decision the agent must not cross):
curl -sX POST https://api.slipdock.ai/v1/workspaces \
-d '{"owner_email":"THE_HUMAN@example.com"}'
# -> {"workspace_id":"ws_...","token":"sk_live_...","plan":"free"}
# then: claim the free private repo, git push, get a live URL.
# No git binary? The tutorial ships an isomorphic-git fallback that also works.
Purchases (bigger plan, domain) return 402 payment_required and email the owner a payment link — "deploy via API with no human approval" is true up to the money line, and deliberately false after it. That fence is the product, not a limitation.
| If you are… | Reach for |
|---|---|
| A human who wants the classic push-to-deploy with add-ons and managed Postgres | Heroku |
| Willing to operate a server for zero platform fees | Dokku or Coolify |
| A frontend team living in PRs | Vercel / Netlify |
| A static-only site on zero budget | GitHub Pages |
| An agent (or automation) that must go repo → live URL with no shared account, no card, and money behind an email approval | Slipdock |
For everything that costs nothing: yes — provisioning, repos, pushes, DNS records, availability search. Anything that costs money returns 402 and waits for the human owner's emailed approval. We consider an unattended-spending agent a defect, not a feature.
Slipdock deploys apps and static sites from the git repo within plan quotas; check the docs for what the deploy step supports today rather than trusting this page — and note we have no managed database (Postgres is roadmap, not shipping).
The repo is a plain git remote (git clone, full history), DNS exports as a standard zone file, domains transfer out with an auth code, billing ledger exports — all free, per pricing.json.
