*codeplain
Spec-as-source platform: agents help write specs in the ***plain language and the hosted renderer generates tested code; specs, not code, are maintained.

In Spec-driven development
Where it stands apart
- How is the main thing licensed? proprietary or closed source (11% of 19 others)
- Can it run entirely on your own device or infrastructure, without the maker's servers? partly (some features need the maker's servers) (16% of 19 others)
- Do you need an account to use it? account required (11% of 19 others)
- Once code exists, what is the spec? the source: changes start in the spec and code follows (5% of 19 others)
- After implementation, what built-in step keeps specs and code aligned? (if several, the first that applies) code is regenerated from the spec (0% of 18 others)
- What format are specs written in? a structured schema or dedicated spec language (6% of 18 others)
- What form does it mainly ship in? a standalone app, IDE, or hosted platform (21% of 19 others)
What it shares with most of the community
- Is it actively maintained? active (74% of 19 others)
- How is it mainly sustained? company with a paid product, tier, or ads (50% of 18 others)
- Who is it for? developers (100% of 19 others)
- Where do specs live? plain files in the project repository (89% of 19 others)

| Question | Answer | Source |
|---|---|---|
| Is it actively maintained? | active | source 2026-10-25 |
| How is the main thing licensed? | stands apart proprietary or closed source Renderer client is Apache-2.0, but rendering runs through the proprietary *codeplain API. | source 2026-10-25 |
| How is it mainly sustained? | company with a paid product, tier, or ads Free trial (50 credits); Pro $500/seat/month. | source 2026-10-25 |
| Can it run entirely on your own device or infrastructure, without the maker's servers? | stands apart partly (some features need the maker's servers) CLI local; requires CODEPLAIN_API_KEY for rendering. | source 2026-10-25 |
| Do you need an account to use it? | stands apart account required Rendering needs CODEPLAIN_API_KEY from a platform.codeplain.ai sign-up. | source 2026-10-26 |
| Who is it for? | developers | source 2026-10-25 |
| Which shared standard or format does it mainly build on? | none of these (its own format or interface) Its own ***plain spec language. | source 2026-10-26 |
| Once code exists, what is the spec? | stands apart the source: changes start in the spec and code follows 'your specifications become the source of truth'; specs are 'the new source code'. | source 2026-10-25 |
| After implementation, what built-in step keeps specs and code aligned? (if several, the first that applies) | stands apart code is regenerated from the spec | source 2026-10-25 |
| What format are specs written in? | stands apart a structured schema or dedicated spec language ***plain: structured English with definitions, implementation, test and functional requirement sections. | source 2026-10-25 |
| Where do specs live? | plain files in the project repository | source 2026-10-25 |
| Which coding agents does it work with? | Not documented plain-forge installs skills for coding agents; list not checked. | source 2026-10-25 |
| What form does it mainly ship in? | stands apart a standalone app, IDE, or hosted platform Hosted rendering platform with CLI and editor. | source 2026-10-25 |
| How is the path from idea to code structured? | no fixed phases | source 2026-10-25 |
| Does a human approve the spec or plan before code is written? | Not documented | source 2026-10-25 |
| By default, once a plan is approved, how is implementation run? | agents run the whole plan with automated review or verification loops Renderer generates and validates code against generated tests. | source 2026-10-25 |
| What does it offer teams beyond sharing files in git? (if both, pick the paid product) | team features in a paid hosted product Pro includes team management. | source 2026-10-25 |
