The short version

  • ProofHub is an all-in-one project management and team collaboration software.
  • Spacelift is free; ProofHub starts at $45/mo.
  • Only ProofHub lists time tracking; only Spacelift lists multi-tool orchestration.
  • Where ProofHub falls short: the Ultimate Control plan advertises $89 a month for the first 3 months and then charges $135, so the headline is an introductory rate.
  • Where Spacelift falls short: three of the five tiers are quote-only, so a shortlist cannot be costed without entering a sales process with each vendor on it.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ProofHub

  • The Ultimate Control plan advertises $89 a month for the first 3 months and then charges $135, so the headline is an introductory rate
  • The Essential plan caps projects at 40 and storage at 15 GB
  • Storage is 100 GB even on the higher plan, which is low for a tool holding project files
  • There is no free tier, and the entry price is a flat $45 a month billed annually

Spacelift

  • Users are unlimited and private workers are metered, so deployment concurrency rather than headcount drives the bill, which inverts how most engineering budgets are built and is easy to under-forecast
  • There is no affordable paid entry point. The free tier stops at two users and the next tier is a five-figure commitment with nothing in between
  • Three of the five tiers are quote-only, so a shortlist cannot be costed without entering a sales process with each vendor on it
  • The self-hosted build lags the hosted one, has no public worker pool and lacks the Azure and Google Cloud integrations available in the SaaS product, with OIDC federation offered as the workaround
  • Stacks, Rego policies, Blueprints, Spaces and Spacelift-managed state are proprietary constructs, so leaving means rebuilding the orchestration layer rather than pointing it at a different runner

Answered from the vendors’ own pages

ProofHub: How much does ProofHub cost?

ProofHub offers two plans: Essential at $45/month (annual) or $50/month (monthly), and Ultimate Control at $89/month (first 3 months) or $135/month thereafter (annual billing).

Source
Spacelift: How is Spacelift priced?

By tier and by private worker count rather than per user. Users are unlimited on every paid plan. The published figure on the pricing page carries no period label, and the FAQ describes the tier as an annual subscription, so confirm the period in writing.

ProofHub: Are per-user fees required with ProofHub?

No. ProofHub includes unlimited users in both Essential and Ultimate Control plans. There are no per-user fees regardless of team size.

Source
Spacelift: Does it support OpenTofu?

Yes, and Spacelift sponsors the OpenTofu project, which is a substantive hedge for anyone avoiding Terraform under the Business Source Licence.

ProofHub: Does ProofHub offer a free trial?

Yes, ProofHub provides a 14-day free trial with no credit card required. You can explore all features before committing.

Source
Spacelift: Is there a self-hosted version?

Yes, described as carrying Enterprise functionality, but it is priced on request and lags the hosted product on cloud integrations.

ProofHub: Can I cancel ProofHub anytime?

Yes. ProofHub has no long-term contracts. You can cancel anytime and switch billing between annual and monthly plans.

Source
Spacelift: Why not just use the CI system we already have?

That is the real comparison. General purpose CI handles state, drift, approval gates and concurrency control for infrastructure poorly, and whether that is worth a five-figure floor depends on how much infrastructure change your organisation actually ships.

Spacelift: What happens to our pipelines if we leave?

They do not port. Rego policies, Blueprints, Spaces and managed state are Spacelift constructs and the orchestration has to be rebuilt elsewhere.
