Agentic harness comparison
Bolt vs Lovable
Compared on where each one runs, which editors it supports, how autonomous it is, and how it bills — the four things that actually decide Bolt vs Lovable. Rankings reflect fit and trade-offs, not a single universal winner; partner links, when present, do not replace that methodology.

Bolt
StackBlitz's browser app builder generates and edits web/mobile project code, runs the development preview in browser WebContainers, and offers Bolt Cloud plus GitHub and external hosting integrations. Plan mode discusses the project without code changes; building and published hosting have separate operational boundaries.
Best for
- Browser-based app prototypes
- GitHub code hand-off
- Piloting managed hosting and data
Watch out
October 2 pricing: Free includes public and private projects, 300K tokens/day and 1M/month. Pro starts at $25/month for 10M tokens without a daily limit; Teams starts at $30/member/month with individual, unshared token allotments. Paid unused tokens last one additional month while the subscription remains active. Hosting/request, database and file limits still apply. Bolt processes prompts/code through AI services even though the development runtime is browser-local. The September 22 privacy policy schedules eligible model-development/dataset licensing from October 7 or the later account-terms date, with opt-out and EEA/UK/Swiss and organization exclusions. Forge has separate affirmative-consent rules dating from September 14; stopping Forge alone does not withdraw consent. These are provider policies, not independent security or quality validation.
Lovable
A full-stack app builder with a browser workflow and desktop/mobile access. Generated code can sync to GitHub, GitLab or Bitbucket; workspace members share one credit balance.
Best for
- Fast web prototypes
- Internal tools
- Teams that want generated code with browser previews
Watch out
October 2 docs: shared workspace credits and unlimited members; Pro starts at $25/month for 100 monthly credits ($250/year), Business at $50 ($500/year), Enterprise by contract. Free has five daily build credits capped at 30/calendar month; Pro/Business have uncapped daily grants. Free/Pro/Business temporarily include 20 Cloud and four app-AI credits/month, with a separate chat allowance; Enterprise grants are contractual. At zero available credits, app AI fails and Cloud-dependent apps can pause while published pages stay live. /goal runs up to ten hours, subject to credit check-ins; ten account-wide free fixes each restore after 24 hours. Free/Pro content and usage may train models unless opted out; Business/Enterprise and app-user data are excluded under the September 15 policy. Publishing snapshots code but is not a guarantee of isolated backend data; findings do not block publication by default. Git sync handles one active branch and creates a repository; it is distinct from importing an existing application.

Which one fits
Autonomy and editor constraints decide this far more reliably than a benchmark score.
If most of your week is small, frequent edits, an assistive workflow beats delegation and an agentic harness sits idle while billing. If you regularly hand over work spanning many files, the reverse is true.
Where one tool requires changing editor and the other does not, that difference usually outweighs any capability gap across a team — rollouts fail on adoption, not capability.
