Twitter 宣佈要廢掉免費的 API 權限

昨天下午的時候看到這則官方在 Twitter 上提到的消息,要廢掉 free tier 的 API access:

但這邊提到的 paid basic tier 的價錢還沒看到公告。以「API Pricing - It’s very dark out here」這邊看到的價格,目前的 premium plan 超級貴:

這下看起來是真的得搬了,目前有好幾隻程式在上面跑 :o

Kagi 公佈了收費三個月後的進展

Kagi 公佈了收費三個月後的進展 (可以參考「Kagi 開始收費了」這篇):「Kagi status update: First three months」。

搜尋的部份 (Kagi 這個產品線),目前有 2600 個付費使用者,以 US$10/mo 的費用來算大概是 US$26K/mo 的收入:

Kagi search is currently serving ~2,600 paid customers. We have seen steady growth since the launch 3 months ago. Note, this is with zero marketing and fully relying on word of mouth. We prefer to keep things this way for now, as we are still developing the product towards our vision of a user-centric web search experience.

後面在講財務狀況也是類似的數字 (幾乎都是 Kagi 的付費收入):

Between Kagi and Orion, we are currently generating around $26,500 USD in monthly recurring revenue, which incidentally about exactly covers our current API and infrastructure costs.

這個收入差不多 cover 目前的 infrastructure 部份,但還有薪資與其他的 operating cost 大約在 US$100K/mo 這個數量級,看起來還有很大的距離:

Between Kagi and Orion, we are currently generating around $26,500 USD in monthly recurring revenue, which incidentally about exactly covers our current API and infrastructure costs.

That means that salaries and all other operating costs (order of magnitude of $100K USD/month) remain a challenge and are still paid out of the founders’ pocket (Kagi remains completely bootstrapped).

然後要大概是目前十倍的付費數量才會打平 (25K 個使用者):

We are planning to reach sustainability at around 25,000 users mark, by further improving the product, introducing new offerings and pricing changes. With the product metrics being as good as they are, we should be able to reach this as our visibility increases.

比較好一點的消息是 churn rate 很低:

Product stickiness is also very high, with churn being lower than 3%.

然後提到每個使用者大約 27 次查詢 (包括 free tier),有些 user 大約在 100 次,peak 是 400 次:

We are currently serving around 70,000 queries a day or around ~27 queries/day/user (this includes free users which are about 10% of total users). There is a lot of variance in use though, with some users regularly searching >100 times a day. Every time we see a search count go >400 times in day we are happy to be an important part of someone’s search experience.

我看了一下自己的用量,看起來偏高一些,但沒到他說的每天平均 100 次:

然後提到了推出新方案的計畫,包括 Teams Plan & Family Plan,而目前在跑的方案會被分類到 Individual Plans。

另外比較重要的是 Individual Plans 有漲價的計畫。新的方案預定分成三個層級,主要是增加了一個 Kagi Starter 的版本:

  • Kagi Unlimited - $19/mo or $180/year ($15/mo) or $288/biennial ($12/mo) - Original Kagi experience, with unlimited searches
  • Kagi Starter ($5/mo; 200 searches) - For casual users who make less than 200 searches per month
  • Free basic - 50 free searches that reset every month


If such change to Individual plans is to occur, we plan to grandfather-in all early adopters (meaning all current and future paid customers, up until this change) allowing them to keep their existing subscription price as long as they don’t cancel it.


Amazon RDS 的 Free Tier 方案包含了 db.t3.micro 與 db.t4g.micro

AWSdb.t3.microdb.t4g.micro 都放進 free tier 了:「Amazon RDS Free Tier now includes db.t3.micro, AWS Graviton2-based db.t4g.micro instances in all commercial regions」。

Customers new to AWS in the past 12 months and who were in regions where db.t2.micro was not available can now create free tier db.t3.micro or db.t4g.micro instances for the remainder of their first 12 months.

看說明是註冊的 12 個月內有這個方案可以用,可以拿來跑一些小東西...

把 Blog 丟到 CloudFront 上

先前在「AWS 流量相關的 Free Tier 增加不少...」這邊有提到一般性的流量從 1GB/month per region 升到 100GB/month,另外 CloudFront 則是大幅增加,從 50GB/month (只有註冊完的前 12 個月) 提升到 1TB/month (不限制 12 個月),另外 CloudFront 到 EC2 中間的流量是不計費的。

剛剛花了點功夫把 blog 從 Cloudflare 搬到 CloudFront 上,另外先對預設的 /* 調整成 no cache,然後針對 /wp-content/* 另外加上 cache 處理,跑一陣子看看有沒有問題再說...

目前比較明顯的改善就是 latency,從 HiNet 連到免費版的 Cloudflare 會導去美國,用 CloudFront 的話就會是台灣了:

另外一方面,這樣國際頻寬的部份就會走進 AWS 的骨幹,比起透過 HiNet 自己連到美國的 PoP 上,理論上應該是會快一些...

AWS 流量相關的 Free Tier 增加不少...

Jeff Barr 出來公告增加 AWS 流量相關的 free tier:「AWS Free Tier Data Transfer Expansion – 100 GB From Regions and 1 TB From Amazon CloudFront Per Month」。

一般性的 data transfer 從 1GB/month/region 變成 100GB/mo,現在是 21 regions 所以不會有反例,另外大多數的人或是團隊也就固定用一兩個 region,這個 free tier 大概可以省個 $10 到 $20 左右?

Data Transfer from AWS Regions to the Internet is now free for up to 100 GB of data per month (up from 1 GB per region). This includes Amazon EC2, Amazon S3, Elastic Load Balancing, and so forth. The expansion does not apply to the AWS GovCloud or AWS China Regions.

另外是 CloudFront 的部份,本來只有前 12 個月有 free tier,現在是開放到所有帳號都有,另外從 50GB/month 升到 1TB/month,這個部份的 free tier 就不少了,大概是 $100 到 $200?

Data Transfer from Amazon CloudFront is now free for up to 1 TB of data per month (up from 50 GB), and is no longer limited to the first 12 months after signup. We are also raising the number of free HTTP and HTTPS requests from 2,000,000 to 10,000,000, and removing the 12 month limit on the 2,000,000 free CloudFront Function invocations per month. The expansion does not apply to data transfer from CloudFront PoPs in China.


This change is effective December 1, 2021 and takes effect with no effort on your part.

這樣好像可以考慮把 blog 與 wiki 都放上去玩玩看,目前這兩個服務都是用 Cloudflare 的 free tier,HiNet 用戶基本上都是連去 Cloudflare 的美西 PoP,偶而離峰時間會用亞洲的點,但都不會是台灣的 PoP...

不過記得之前 WordPress + CloudFront 有些狀況,再研究看看要怎麼弄好了...

Figma 限縮免費帳號的功能

Plurk 上的這篇看到的,Figma 的 Free Starter Plan 縮減功能:「Starter plan updates」。

這步算是要使用者掏錢出來,進入養套殺裡「殺」的階段了。不過每個編輯者 USD$15/month 以價錢來說還好 (年繳的話還有一些折扣),團隊大多數的 viewer 是不額外收費的。

LastPass 開始進入「殺」的階段,免費使用者只能在一個平台上使用

LastPass 進入了「套養殺」最後一個階段「殺」,宣佈縮減 LastPass Free 的可用範圍。在 2021/03/16 開始 (一個月後),LastPass Free 的使用者只能選擇一個平台使用,像是「桌機平台」,或是「行動平台」:「LastPass’ free tier will become a lot less useful next month」,官方的新聞稿則是在「Changes to LastPass Free」這邊。

官方有提供第一年的限時優惠 (換算起來應該是一年 USD$27),但不給既有用戶,現有的用戶如果要的話得自己換帳號 export & import,不然就是用原價殺 (一年 USD$36):

If you’d like unlimited device type access and email support, you can upgrade from Free to LastPass Premium for a limited time, for $2.25 per month (billed annually). *

*Additional Terms and Conditions: Advertised price valid for new users on their first year of LastPass Premium. Price not valid for renewals or existing customers and cannot be used for other LastPass plans, products or services.


話說回來,這種東西我自己還是偏好用 open source 方案,然後自己搭同步機制,不過目前看到的方案在跨桌機平台與行動平台的確是痛點... 有需求的人應該還是會選 LastPass 或是 1Password 這樣的方案。

Travis CI 停止提供服務給 Open Source 專案

Hacker News Daily 上看到這個,在講 Travis CI 終止對 open source 專案的服務:「Travis CI is no longer providing CI minutes for open source projects」。

有不少專案已經改用其他 CI 服務的 free tier 做,像是 GitHub ActionsCircleCI 都有提供。

看了一下 Hacker News 上的討論,不少人是可以理解不會有永遠免費的午餐,只是這次 Travis CI 的處理讓大家覺得比較討厭的是,一方面官方一直跟 open source community 說我們很願意支援 open source community (前幾個禮拜官方 blog 還有發文重申這件事情),另外一方面是一直在朝著關閉服務走:從限制 10K credits 開始,到現在不會再提供 credit 給 open source 專案。


? 2018: Travis CI announces they are starting the process of merging, which provided free builds for OSS projects, into, which until then was only for paying customers. They promise OSS builds will continue to be free.

? 2020: Travis CI announces they are shutting down at the end of the year and all projects have to move to They promise OSS builds will continue to be free.

Early November 2020: switches from providing unlimited builds for OSS to only providing 10k one-time credits by default. Projects that meet certain guidelines (e.g. no one paid to work on them) can apply for recurring credits.

Later in November 2020: CI for many OSS projects that had migrated to starts to fail, as they've exhausted their 10K credits.

Dec 2020: If what is reported here is accurate, Travis CI stop providing any recurring OSS credits. CI breaks for the remaining OSS projects on

Jan 2021: shuts down. CI will be broken for all projects using it. They'll have the option of migrating to, but will soon break again as they exhaust their 10k credits.

這種服務非常吃 CPU resource,大型專案如果每個 push 或是每個 pull request 都跑一輪完整的測試,成本應該不低,大概可以理解為什麼 Travis CI 會這樣決定,不過態度就...

其他家有提供 free tier 的 CI 最近應該會湧入不少人,這幾個月可以看看其他家會不會也跟進,另外一方面應該也會有人開始自架?

Elasticsearch 提供免費版本的安全功能

Elasticsearch 決定將基本的安全功能從付費功能轉為免費釋出,很明顯的是受到 Open Distro for Elasticsearch 的壓力而做出的改變:「Security for Elasticsearch is now free」。

要注意的是這不是 open source 版本,只是將這些功能放到 basic tier 裡讓使用者免費使用:

Previously, these core security features required a paid Gold subscription. Now they are free as a part of the Basic tier. Note that our advanced security features — from single sign-on and Active Directory/LDAP authentication to field- and document-level security — remain paid features.

這代表 Open Distro for Elasticsearch 提供的還是比較多:

With Open Distro for Elasticsearch, you can leverage your existing authentication infrastructure such as LDAP/Active Directory, SAML, Kerberos, JSON web tokens, TLS certificates, and Proxy authentication/SSO for user authentication. An internal user repository with support for basic HTTP authentication is also avaliable for easy setup and evaluation.

Granular, role-based access control enables you to control the actions a user can perform on your Elasticsearch cluster. Roles control cluster operations, access to indices, and even the fields and documents users can access. Open Distro for Elasticsearch also supports multi-tenant environments, allowing multiple teams to share the same cluster while only being able to access their team's data and dashboards.

目前看起來還是可以朝 Open Distro for Elasticsearch 靠過去...
