Plaid Cymru would hold an independence referendum within five years if it came to power in May's Senedd election.
Launching its manifesto, the party said it offered the "most radical programme" in "any Welsh election since 1945".
Its plans include creating 60,000 green jobs, extending free school meals and social care free at the point of need.
Economists cost checking the promises called them "achievable" but could not say if "the spending is adequate to achieve the desired results".
Plaid leader Adam Price said the "practical, deliverable and fully costed policies" would lead to a "fairer, greener, and more prosperous future for Wales".
