Free tier	a free trial project with no expiry, described only as 'just enough resources to explore the platform and do basic work', with no internet access and a small idle timeout unit none; metered on none; No RAM, CPU or hour number is published anywhere reachable today. The zero is the network, not the clock.
Price	none stated
Per-object cap	not applicable: the unit is a session, not an object
Retention	trial projects do not expire at the moment; a free project can be stopped at any time
Egress	no outbound internet at all from a free project free_allowance: 0 bytes
Identity	email an account; the free trial project needs no card
Limits	write-gated no internet access from a free project; a licence is required source volume-quota unpublished and small: 'Your hardware resources are quite limited' source
Binding	write-gated no outbound network means no pip, no git clone and no API call, which ends most work before any quota is reached
Interface	rest, ssh, cli a browser IDE with a Linux terminal, Jupyter, RStudio and LaTeX
Tooling	the web IDE and its terminal; pip and git clone both fail without network
Composes with	a free LaTeX and R workbench with no internet, which rules out installing anything or fetching data
Reliability	a free project can be stopped at any time and the docs say it happens at least daily, so long computations need checkpointing
Notes	CoCalc moved its pricing to cocalc.ai; cocalc.com/pricing now 404s through the broker. The free tier publishes no number at all, which is why this record has dashes where a shape should be.
Evidence rung	documented the no-internet rule and the idle/session language are quoted from the manual today. RAM and CPU are unverified because neither the pricing page nor the manual publishes a number for the free tier.
Checked	2026-10-25 (live); stale on 2026-11-24
Parsed numbers	`$.extras.m10h_usd` price USD0.0 / month `$.extras.m24h_usd` price USD0.0 / month

date	source	what it proved
2026-10-24	doc.cocalc.com/upgrades.html	quoted: 'Processes running inside a free project are not allowed to directly access the internet.'
2026-10-24	doc.cocalc.com/trial.html	quoted, with a link and code spans in the original: 'You do not have direct Internet access. You can upload files to CoCalc from your computer, but not from other sites. You cannot `git clone` repositories from GitHub and you cannot [install packages](https://doc.cocalc.com/howto/install-python-lib.html) even as a regular user via `pip`.'
2026-10-24	doc.cocalc.com/trial.html	quoted: 'Idle timeout is small and overall session duration is limited.'
2026-10-24	doc.cocalc.com/trial.html	quoted: 'Yes, you can - trial projects do not expire at the moment.'
2026-10-24	cocalc.ai/pricing	quoted: 'Start using CoCalc with just enough resources to explore the platform and do basic work.' - the Free tier carries no number
2026-10-24	cocalc.ai/pricing	quoted: 'Network access' appears as a benefit of the Basic and Standard tiers, not of Free
