## Heroku Open Source

- `compute/heroku-open-source` | qualifies-with-caveat | evidence documented | binding write-gated | category platform host
- needs card yes, phone no, ID no, institution no | verified 2026-11-04T02:24:32.966Z (live) | stale on 2026-12-05
- url https://www.heroku.com/open-source-credit-program/
- free tier: 'one year of platform credits to qualifying Open Source Software projects hosted on Heroku', paid as 'a set credit allocation every month for 12 months', usable on 'Heroku Dynos, Heroku Postgres, and Heroku Key-Value Store'. Salesforce 'will determine the credit allocation amount based on project need and use', so no figure is published. | unit: none | metered on: wall-clock | read on: 2026-10-22 | source: [1] | note: recurring-credit
- per-object cap: not applicable | source: [1]
- retention: not applicable | source: [1]
- egress: network bandwidth is soft limited at 2TB per app per month; no per-GB overage price is published on the limits page read | metered: yes | free allowance: 2TB per app per month (soft limit) | source: [1]
- identity: card | detail: a card is required before applying: the programme page states the account must be verified with a credit or debit card before applying and any monthly overage bills that card, so a debit card is accepted alongside credit. No hold or authorisation amount is stated, whether prepaid cards are accepted is not stated, and the programme adds a second gate — "you must be a maintainer on the open source software project and its supporting infra must run or intend to run on Heroku"
- interface: cli, rest
- limits:
  - write-gated (binding): The account must be verified with a credit or debit card before applying and any monthly overage bills the card; the allocation is set by Salesforce and unused credit is forfeited monthly. [1]
- limits note: The account must be verified with a credit or debit card before applying and any monthly overage bills the card; the allocation is set by Salesforce and unused credit is forfeited monthly.
- binding note: the same as limits note
- interface detail: the Heroku CLI and the Heroku Platform API
- tooling: the Heroku CLI (macOS, Windows, Linux) and the Platform API reachable with curl and a token
- composes with: Dynos plus Postgres plus Key-Value store on one monthly allocation covers a small always-on service with state, which is the piece most free student and OSS tiers leave out: a database that survives the free tier ending.
- reliability: no reliability event recorded
- notes: The gate that matters is directional: the project must run or intend to run on Heroku, so this does not pay for a workload hosted elsewhere. Heroku still sells dynos, so this is a live programme rather than a legacy one. Amount is null by design, not by omission: the terms hand the allocation to Salesforce.
- extras:
  - facets.class: vendor-oss-credits
  - facets.free_tier_kind: recurring-credit
- evidence:
  - [1] 2026-10-22: quoted the 12-month monthly allocation, the covered products, 'Any unused portion of the monthly credit allocation is forfeited', the card-verification requirement, the monthly review cadence, and 'The program is open people globally'

  - [3] 2026-11-03: a CLI manages apps | capture: sha256:a13e767a26d226e7a487a360813b2ae8300c1061f15839044b3764ba68acb191 | quote: The Heroku Command Line Interface (CLI) is an essential part of using Heroku.

- free tier: no free dyno: the pricing page prices dynos as containers with no USD 0 row | unit: none | metered on: none | read on: 2026-10-24 | source: [1]
- per-object cap: not applicable: nothing free
- retention: not applicable

- limits note: not stated
- binding note: there is no free tier to exhaust.
- tooling: the same as limits note

- notes: The accurate verdict for the free-tier question is paid-only: there is no free dyno at any identity level, and the student pack is a credit programme, not a tier. This is a verdict change the parent should carry into history.

- extras:
  - keep_rate: 1.0
  - billing_model: monthly

  - session_cap.note: a dyno runs until stopped or scaled to zero

  - [2] 2026-10-22: 'If you are registered with the GitHub Student Developer Pack, you are eligible to receive platform credits worth $13 per month for 24 months (for a total value of $312)', quoted; the Gate is the Student Developer Pack, whose own requirements state the applicant must be 'enrolled in a degree- or diploma-granting program' and 'provide documents that prove your current student status'
  - [1] 2026-10-24: quoted: 'Dynos are the heart of every Heroku app—lightweight, isolated containers that handle your code, dependencies, and scaling', with no free plan or free dyno row on the page
